PHP-CRUD-API

Single file PHP 7 script that adds a REST API to a MySQL/MariaDB, PostgreSQL, SQL Server or SQLite database.

NB: This is the TreeQL reference implementation in PHP.

There are also proof-of-concept ports of this script that only support basic REST CRUD functionality in: PHP, Java, Go, C# .net core, Node.js and Python.

Requirements

PHP 7.0 or higher with PDO drivers enabled for one of these database systems:
- MySQL 5.6 / MariaDB 10.0 or higher for spatial features in MySQL
- PostgreSQL 9.1 or higher with PostGIS 2.0 or higher for spatial features
- SQL Server 2012 or higher (2017 for Linux support)
- SQLite 3.16 or higher (spatial features NOT supported)

Installation

This is a single file application! Upload “api.php” somewhere and enjoy!

For local development you may run PHP’s built-in web server:

php -S localhost:8080

Test the script by opening the following URL:

http://localhost:8080/api.php/records/posts/1

Don’t forget to modify the configuration at the bottom of the file.

Alternatively you can integrate this project into the web framework of your choice, see:

In these integrations Composer is used to load this project as a dependency.

Configuration

Edit the following lines in the bottom of the file “api.php”:

$config = new Config([
    'username' => 'xxx',
    'password' => 'xxx',
    'database' => 'xxx',
]);

These are all the configuration options and their default value between brackets:

“driver”: mysql, pgsql, sqlsrv or sqlite (mysql)
“address”: Hostname (or filename) of the database server (localhost)
“port”: TCP port of the database server (defaults to driver default)
“username”: Username of the user connecting to the database (no default)
“password”: Password of the user connecting to the database (no default)
“database”: Database the connecting is made to (no default)
“tables”: Comma separated list of tables to publish (defaults to ‘all’)
“middlewares”: List of middlewares to load (cors)
“controllers”: List of controllers to load (records,geojson,openapi)
“openApiBase”: OpenAPI info ({"info":{"title":"PHP-CRUD-API","version":"1.0.0"}})
“cacheType”: TempFile, Redis, Memcache, Memcached or NoCache (TempFile)
“cachePath”: Path/address of the cache (defaults to system’s temp directory)
“cacheTime”: Number of seconds the cache is valid (10)
“debug”: Show errors in the “X-Exception” headers (false)
“basePath”: URI base path of the API (determined using PATH_INFO by default)

All configuration options are also available as environment variables. Write the config option with capitals, a “PHP_CRUDAPI” prefix and underscores for word breakes, so for instance:

PHP_CRUD_API_DRIVER=mysql
PHP_CRUD_API_ADDRESS=localhost
PHP_CRUD_API_PORT=3306
PHP_CRUD_API_DATABASE=php-crud-api
PHP_CRUD_API_USERNAME=php-crud-api
PHP_CRUD_API_PASSWORD=php-crud-api
PHP_CRUD_API_DEBUG=1

The environment variables take precedence over the PHP configuration.

Compilation

You can install all dependencies of this project using the following command:

php install.php

You can compile all files into a single “api.php” file using:

php build.php

NB: The install script will patch the dependencies in the vendor directory for PHP 7.0 compatibility.

Development

You can access the non-compiled code at the URL:

http://localhost:8080/src/records/posts/1

The non-compiled code resides in the “src” and “vendor” directories. The “vendor” directory contains the dependencies.

Updating dependencies

You can update all dependencies of this project using the following command:

php update.php

This script will install and run Composer to update the dependencies.

NB: The update script will patch the dependencies in the vendor directory for PHP 7.0 compatibility.

TreeQL, a pragmatic GraphQL

TreeQL allows you to create a “tree” of JSON objects based on your SQL database structure (relations) and your query.

It is loosely based on the REST standard and also inspired by json:api.

CRUD + List

The example posts table has only a a few fields:

posts  
=======
id     
title  
content
created

The CRUD + List operations below act on this table.

Create

If you want to create a record the request can be written in URL format as:

POST /records/posts

You have to send a body containing:

{
    "title": "Black is the new red",
    "content": "This is the second post.",
    "created": "2018-03-06T21:34:01Z"
}

And it will return the value of the primary key of the newly created record:

Read

To read a record from this table the request can be written in URL format as:

GET /records/posts/1

Where “1” is the value of the primary key of the record that you want to read. It will return:

{
    "id": 1
    "title": "Hello world!",
    "content": "Welcome to the first post.",
    "created": "2018-03-05T20:12:56Z"
}

On read operations you may apply joins.

Update

To update a record in this table the request can be written in URL format as:

PUT /records/posts/1

Where “1” is the value of the primary key of the record that you want to update. Send as a body:

{
    "title": "Adjusted title!"
}

This adjusts the title of the post. And the return value is the number of rows that are set:

Delete

If you want to delete a record from this table the request can be written in URL format as:

DELETE /records/posts/1

And it will return the number of deleted rows:

List

To list records from this table the request can be written in URL format as:

GET /records/posts

It will return:

{
    "records":[
        {
            "id": 1,
            "title": "Hello world!",
            "content": "Welcome to the first post.",
            "created": "2018-03-05T20:12:56Z"
        }
    ]
}

On list operations you may apply filters and joins.

Filters

Filters provide search functionality, on list calls, using the “filter” parameter. You need to specify the column name, a comma, the match type, another commma and the value you want to filter on. These are supported match types:

“cs”: contain string (string contains value)
“sw”: start with (string starts with value)
“ew”: end with (string end with value)
“eq”: equal (string or number matches exactly)
“lt”: lower than (number is lower than value)
“le”: lower or equal (number is lower than or equal to value)
“ge”: greater or equal (number is higher than or equal to value)
“gt”: greater than (number is higher than value)
“bt”: between (number is between two comma separated values)
“in”: in (number or string is in comma separated list of values)
“is”: is null (field contains “NULL” value)

You can negate all filters by prepending a “n” character, so that “eq” becomes “neq”. Examples of filter usage are:

GET /records/categories?filter=name,eq,Internet
GET /records/categories?filter=name,sw,Inter
GET /records/categories?filter=id,le,1
GET /records/categories?filter=id,ngt,1
GET /records/categories?filter=id,bt,0,1
GET /records/categories?filter=id,in,0,1

Output:

{
    "records":[
        {
            "id": 1
            "name": "Internet"
        }
    ]
}

In the next section we dive deeper into how you can apply multiple filters on a single list call.

Multiple filters

Filters can be a by applied by repeating the “filter” parameter in the URL. For example the following URL:

GET /records/categories?filter=id,gt,1&filter=id,lt,3

will request all categories “where id > 1 and id < 3”. If you wanted “where id = 2 or id = 4” you should write:

GET /records/categories?filter1=id,eq,2&filter2=id,eq,4

As you see we added a number to the “filter” parameter to indicate that “OR” instead of “AND” should be applied. Note that you can also repeat “filter1” and create an “AND” within an “OR”. Since you can also go one level deeper by adding a letter (a-f) you can create almost any reasonably complex condition tree.

NB: You can only filter on the requested table (not on it’s included tables) and filters are only applied on list calls.

Column selection

By default all columns are selected. With the “include” parameter you can select specific columns. You may use a dot to separate the table name from the column name. Multiple columns should be comma separated. An asterisk (”*“) may be used as a wildcard to indicate “all columns”. Similar to “include” you may use the “exclude” parameter to remove certain columns:

GET /records/categories/1?include=name
GET /records/categories/1?include=categories.name
GET /records/categories/1?exclude=categories.id

Output:

    {
        "name": "Internet"
    }

NB: Columns that are used to include related entities are automatically added and cannot be left out of the output.

Ordering

With the “order” parameter you can sort. By default the sort is in ascending order, but by specifying “desc” this can be reversed:

GET /records/categories?order=name,desc
GET /records/categories?order=id,desc&order=name

Output:

    {
        "records":[
            {
                "id": 3
                "name": "Web development"
            },
            {
                "id": 1
                "name": "Internet"
            }
        ]
    }

NB: You may sort on multiple fields by using multiple “order” parameters. You can not order on “joined” columns.

Limit size

The “size” parameter limits the number of returned records. This can be used for top N lists together with the “order” parameter (use descending order).

GET /records/categories?order=id,desc&size=1

Output:

    {
        "records":[
            {
                "id": 3
                "name": "Web development"
            }
        ]
    }

NB: If you also want to know to the total number of records you may want to use the “page” parameter.

Pagination

The “page” parameter holds the requested page. The default page size is 20, but can be adjusted (e.g. to 50).

GET /records/categories?order=id&page=1
GET /records/categories?order=id&page=1,50

Output:

    {
        "records":[
            {
                "id": 1
                "name": "Internet"
            },
            {
                "id": 3
                "name": "Web development"
            }
        ],
        "results": 2
    }

NB: Since pages that are not ordered cannot be paginated, pages will be ordered by primary key.

Joins

Let’s say that you have a posts table that has comments (made by users) and the posts can have tags.

posts    comments  users     post_tags  tags
=======  ========  =======   =========  ======= 
id       id        id        id         id
title    post_id   username  post_id    name
content  user_id   phone     tag_id
created  message

When you want to list posts with their comments users and tags you can ask for two “tree” paths:

posts -> comments  -> users
posts -> post_tags -> tags

These paths have the same root and this request can be written in URL format as:

GET /records/posts?join=comments,users&join=tags

Here you are allowed to leave out the intermediate table that binds posts to tags. In this example you see all three table relation types (hasMany, belongsTo and hasAndBelongsToMany) in effect:

“post” has many “comments”
“comment” belongs to “user”
“post” has and belongs to many “tags”

This may lead to the following JSON data:

{
    "records":[
        {
            "id": 1,
            "title": "Hello world!",
            "content": "Welcome to the first post.",
            "created": "2018-03-05T20:12:56Z",
            "comments": [
                {
                    id: 1,
                    post_id: 1,
                    user_id: {
                        id: 1,
                        username: "mevdschee",
                        phone: null,
                    },
                    message: "Hi!"
                },
                {
                    id: 2,
                    post_id: 1,
                    user_id: {
                        id: 1,
                        username: "mevdschee",
                        phone: null,
                    },
                    message: "Hi again!"
                }
            ],
            "tags": []
        },
        {
            "id": 2,
            "title": "Black is the new red",
            "content": "This is the second post.",
            "created": "2018-03-06T21:34:01Z",
            "comments": [],
            "tags": [
                {
                    id: 1,
                    message: "Funny"
                },
                {
                    id: 2,
                    message: "Informational"
                }
            ]
        }
    ]
}

You see that the “belongsTo” relationships are detected and the foreign key value is replaced by the referenced object. In case of “hasMany” and “hasAndBelongsToMany” the table name is used a new property on the object.

Batch operations

When you want to create, read, update or delete you may specify multiple primary key values in the URL. You also need to send an array instead of an object in the request body for create and update.

To read a record from this table the request can be written in URL format as:

GET /records/posts/1,2

The result may be:

[
        {
            "id": 1,
            "title": "Hello world!",
            "content": "Welcome to the first post.",
            "created": "2018-03-05T20:12:56Z"
        },
        {
            "id": 2,
            "title": "Black is the new red",
            "content": "This is the second post.",
            "created": "2018-03-06T21:34:01Z"
        }
]

Similarly when you want to do a batch update the request in URL format is written as:

PUT /records/posts/1,2

Where “1” and “2” are the values of the primary keys of the records that you want to update. The body should contain the same number of objects as there are primary keys in the URL:

[   
    {
        "title": "Adjusted title for ID 1"
    },
    {
        "title": "Adjusted title for ID 2"
    }        
]

This adjusts the titles of the posts. And the return values are the number of rows that are set:

1,1

Which means that there were two update operations and each of them had set one row. Batch operations use database transactions, so they either all succeed or all fail (successful ones get roled back).

Spatial support

For spatial support there is an extra set of filters that can be applied on geometry columns and that starting with an “s”:

“sco”: spatial contains (geometry contains another)
“scr”: spatial crosses (geometry crosses another)
“sdi”: spatial disjoint (geometry is disjoint from another)
“seq”: spatial equal (geometry is equal to another)
“sin”: spatial intersects (geometry intersects another)
“sov”: spatial overlaps (geometry overlaps another)
“sto”: spatial touches (geometry touches another)
“swi”: spatial within (geometry is within another)
“sic”: spatial is closed (geometry is closed and simple)
“sis”: spatial is simple (geometry is simple)
“siv”: spatial is valid (geometry is valid)

These filters are based on OGC standards and so is the WKT specification in which the geometry columns are represented.

GeoJSON

The GeoJSON support is a read-only view on the tables and records in GeoJSON format. These requests are supported:

method path                  - operation - description
----------------------------------------------------------------------------------------
GET    /geojson/{table}      - list      - lists records as a GeoJSON FeatureCollection
GET    /geojson/{table}/{id} - read      - reads a record by primary key as a GeoJSON Feature

The “/geojson” endpoint uses the “/records” endpoint internally and inherits all functionality, such as joins and filters. It also supports a “geometry” parameter to indicate the name of the geometry column in case the table has more than one. For map views it supports the “bbox” parameter in which you can specify upper-left and lower-right coordinates (comma separated). The following Geometry types are supported by the GeoJSON implementation:

Point
MultiPoint
LineString
MultiLineString
Polygon
MultiPolygon

The GeoJSON functionality is enabled by default, but can be disabled using the “controllers” configuration.

Middleware

You can enable the following middleware using the “middlewares” config parameter:

“firewall”: Limit access to specific IP addresses
“sslRedirect”: Force connection over HTTPS instead of HTTP
“cors”: Support for CORS requests (enabled by default)
“xsrf”: Block XSRF attacks using the ‘Double Submit Cookie’ method
“ajaxOnly”: Restrict non-AJAX requests to prevent XSRF attacks

If you don’t specify these parameters in the configuration, then the default values (between brackets) are used.

In the sections below you find more information on the built-in middleware.

Authentication

Currently there are three types of authentication supported. They all store the authenticated user in the $_SESSION super global. This variable can be used in the authorization handlers to decide wether or not sombeody should have read or write access to certain tables, columns or records. The following overview shows the kinds of authentication middleware that you can enable.

Name	Middleware	Authenticated via	Users are stored in	Session variable
Database	dbAuth	’/login’ endpoint	database table	`$_SESSION['user']`
Basic	basicAuth	‘Authorization’ header	’.htpasswd’ file	`$_SESSION['username']`
JWT	jwtAuth	‘Authorization’ header	identity provider	`$_SESSION['claims']`

Below you find more information on each of the authentication types.

Database authentication

The database authentication middleware defines three new routes:

method path       - parameters                      - description
---------------------------------------------------------------------------------------------------
GET    /me        -                                 - returns the user that is currently logged in
POST   /register  - username, password              - adds a user with given username and password
POST   /login     - username, password              - logs a user in by username and password
POST   /password  - username, password, newPassword - updates the password of the logged in user
POST   /logout    -                                 - logs out the currently logged in user

A user can be logged in by sending it’s username and password to the login endpoint (in JSON format). The authenticated user (with all it’s properties) will be stored in the $_SESSION['user'] variable. The user can be logged out by sending a POST request with an empty body to the logout endpoint. The passwords are stored as hashes in the password column in the users table. You can register a new user using the register endpoint, but this functionality must be turned on using the “dbAuth.regsiterUser” configuration parameter.

It is IMPORTANT to restrict access to the users table using the ‘authorization’ middleware, otherwise all users can freely add, modify or delete any account! The minimal configuration is shown below:

'middlewares' => 'dbAuth,authorization',
'authorization.tableHandler' => function ($operation, $tableName) {
    return $tableName != 'users';
},

Note that this middleware uses session cookies and stores the logged in state on the server.

Basic authentication

The Basic type supports a file (by default ‘.htpasswd’) that holds the users and their (hashed) passwords separated by a colon (‘:’). When the passwords are entered in plain text they fill be automatically hashed. The authenticated username will be stored in the $_SESSION['username'] variable. You need to send an “Authorization” header containing a base64 url encoded and colon separated username and password after the word “Basic”.

Authorization: Basic dXNlcm5hbWUxOnBhc3N3b3JkMQ

This example sends the string “username1:password1”.

JWT authentication

The JWT type requires another (SSO/Identity) server to sign a token that contains claims. Both servers share a secret so that they can either sign or verify that the signature is valid. Claims are stored in the $_SESSION['claims'] variable. You need to send an “X-Authorization” header containing a base64 url encoded and dot separated token header, body and signature after the word “Bearer” (read more about JWT here). The standard says you need to use the “Authorization” header, but this is problematic in Apache and PHP.

X-Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWUsImlhdCI6IjE1MzgyMDc2MDUiLCJleHAiOjE1MzgyMDc2MzV9.Z5px_GT15TRKhJCTHhDt5Z6K6LRDSFnLj8U5ok9l7gw

This example sends the signed claims:

{
  "sub": "1234567890",
  "name": "John Doe",
  "admin": true,
  "iat": "1538207605",
  "exp": 1538207635
}

NB: The JWT implementation only supports the RSA and HMAC based algorithms.

Configure and test JWT authentication with Auth0

First you need to create an account on Auth0. Once logged in, you have to create an application (its type does not matter). Collect the Domain and Client ID and keep them for a later use. Then, create an API: give it a name and fill the identifier field with your API endpoint’s URL.

Then you have to configure the jwtAuth.secrets configuration in your api.php file. Don’t fill it with the secret you will find in your Auth0 application settings but with a public certificate. To find it, go to the settings of your application, then in “Extra settings”. You will now find a “Certificates” tab where you will find your Public Key in the Signing Certificate field.

To test your integration, you can copy the auth0/vanilla.html file. Be sure to fill these three variables:

authUrl with your Auth0 domain
clientId with your Client ID
audience with the API URL you created in Auth0

⚠️ If you don’t fill the audience parameter, it will not work because you won’t get a valid JWT.

You can also change the url variable, used to test the API with authentication.

Configure and test JWT authentication with Firebase

First you need to create a Firebase project on the Firebase console. Add a web application to this project and grab the code snippet for later use.

Then you have to configure the jwtAuth.secrets configuration in your api.php file. This can be done as follows:

a. Log a user in to your Firebase-based app, get an authentication token for that user b. Go to https://jwt.io/ and paste the token in the decoding field c. Read the decoded header information from the token, it will give you the correct kid d. Grab the public key via this URL, which corresponds to your kid from previous step e. Now, just fill jwtAuth.secrets with your public key in the api.php

Here is an example of what it should look like in the configuration:

...,
'middlewares' => 'cors, jwtAuth, authorization',
        'jwtAuth.secrets' => "ce5ced6e40dcd1eff407048867b1ed1e706686a0:-----BEGIN CERTIFICATE-----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\nk61HD29mROYjl95Mko2BxL+76To7+pmn73U9auT+xfA=\n-----END CERTIFICATE-----\n",
        'cors.allowedOrigins' => '*',

Notes:

The kid:key pair is formatted as a string
Do not include spaces before or after the ‘:’
Use double quotation marks (“) around the string text
The string must contain the linefeeds (\n)

To test your integration, you can copy the firebase/vanilla.html file and the firebase/vanilla-success.html file, used as a “success” page and to display the API result.

Replace, in both files, the Firebase configuration (firebaseConfig object).

You can also change the url variable, used to test the API with authentication.

Authorizing operations

The Authorization model acts on “operations”. The most important ones are listed here:

method path                  - operation - description
----------------------------------------------------------------------------------------
GET    /records/{table}      - list      - lists records
POST   /records/{table}      - create    - creates records
GET    /records/{table}/{id} - read      - reads a record by primary key
PUT    /records/{table}/{id} - update    - updates columns of a record by primary key
DELETE /records/{table}/{id} - delete    - deletes a record by primary key
PATCH  /records/{table}/{id} - increment - increments columns of a record by primary key

The “/openapi” endpoint will only show what is allowed in your session. It also has a special “document” operation to allow you to hide tables and columns from the documentation.

For endpoints that start with “/columns” there are the operations “reflect” and “remodel”. These operations can display or change the definition of the database, table or column. This functionality is disabled by default and for good reason (be careful!). Add the “columns” controller in the configuration to enable this functionality.

Authorizing tables, columns and records

By default all tables, columns and paths are accessible. If you want to restrict access to some tables you may add the ‘authorization’ middleware and define a ‘authorization.tableHandler’ function that returns ‘false’ for these tables.

'authorization.tableHandler' => function ($operation, $tableName) {
    return $tableName != 'license_keys';
},

The above example will restrict access to the table ‘license_keys’ for all operations.

'authorization.columnHandler' => function ($operation, $tableName, $columnName) {
    return !($tableName == 'users' && $columnName == 'password');
},

The above example will restrict access to the ‘password’ field of the ‘users’ table for all operations.

'authorization.recordHandler' => function ($operation, $tableName) {
    return ($tableName == 'users') ? 'filter=username,neq,admin' : '';
},

The above example will disallow access to user records where the username is ‘admin’. This construct adds a filter to every executed query.

'authorization.pathHandler' => function ($path) {
    return $path === 'openapi' ? false : true;
},

The above example will disabled the /openapi route.

NB: You need to handle the creation of invalid records with a validation (or sanitation) handler.

SQL GRANT authorization

You can alternatively use database permissons (SQL GRANT statements) to define the authorization model. In this case you should not use the “authorization” middleware, but you do need to use the “reconnect” middleware. The handlers of the “reconnect” middleware allow you to specify the correct username and password, like this:

'reconnect.usernameHandler' => function () {
    return 'mevdschee';
},
'reconnect.passwordHandler' => function () {
    return 'secret123';
},

This will make the API connect to the database specifying “mevdschee” as the username and “secret123” as the password. The OpenAPI specification is less specific on allowed and disallowed operations when you are using database permissions, as the permissions are not read in the reflection step.

NB: You may want to retrieve the username and password from the session (the “$_SESSION” variable).

Sanitizing input

By default all input is accepted and sent to the database. If you want to strip (certain) HTML tags before storing you may add the ‘sanitation’ middleware and define a ‘sanitation.handler’ function that returns the adjusted value.

'sanitation.handler' => function ($operation, $tableName, $column, $value) {
    return is_string($value) ? strip_tags($value) : $value;
},

The above example will strip all HTML tags from strings in the input.

Type sanitation

If you enable the ‘sanitation’ middleware, then you (automatically) also enable type sanitation. When this is enabled you may:

send leading and trailing whitespace in a non-character field (it will be ignored).
send a float to an integer or bigint field (it will be rounded).
send a base64url encoded string (it will be converted to regular base64 encoding).
send a time/date/timestamp in any strtotime accepted format (it will be converted).

You may use the config settings “sanitation.types” and “sanitation.tables”’ to define for which types and in which tables you want to apply type sanitation (defaults to ‘all’). Example:

'sanitation.types' => 'date,timestamp',
'sanitation.tables' => 'posts,comments',

Here we enable the type sanitation for date and timestamp fields in the posts and comments tables.

Validating input

By default all input is accepted and sent to the database. If you want to validate the input in a custom way, you may add the ‘validation’ middleware and define a ‘validation.handler’ function that returns a boolean indicating whether or not the value is valid.

'validation.handler' => function ($operation, $tableName, $column, $value, $context) {
    return ($column['name'] == 'post_id' && !is_numeric($value)) ? 'must be numeric' : true;
},

When you edit a comment with id 4 using:

PUT /records/comments/4

And you send as a body:

{"post_id":"two"}

Then the server will return a ‘422’ HTTP status code and nice error message:

{
    "code": 1013,
    "message": "Input validation failed for 'comments'",
    "details": {
        "post_id":"must be numeric"
    }
}

You can parse this output to make form fields show up with a red border and their appropriate error message.

Type validations

If you enable the ‘validation’ middleware, then you (automatically) also enable type validation. This includes the following error messages:

error message	reason	applies to types
cannot be null	unexpected null value	(any non-nullable column)
illegal whitespace	leading/trailing whitespace	integer bigint decimal float double boolean
invalid integer	illegal characters	integer bigint
string too long	too many characters	varchar varbinary
invalid decimal	illegal characters	decimal
decimal too large	too many digits before dot	decimal
decimal too precise	too many digits after dot	decimal
invalid float	illegal characters	float double
invalid boolean	use 1, 0, true or false	boolean
invalid date	use yyyy-mm-dd	date
invalid time	use hh:mm:ss	time
invalid timestamp	use yyyy-mm-dd hh:mm:ss	timestamp
invalid base64	illegal characters	varbinary, blob

You may use the config settings “validation.types” and “validation.tables”’ to define for which types and in which tables you want to apply type validation (defaults to ‘all’). Example:

'validation.types' => 'date,timestamp',
'validation.tables' => 'posts,comments',

Here we enable the type validation for date and timestamp fields in the posts and comments tables.

NB: Types that are enabled will be checked for null values when the column is non-nullable.

Multi-tenancy support

Two forms of multi-tenancy are supported:

Single database, where every table has a tenant column (using the “multiTenancy” middleware).
Multi database, where every tenant has it’s own database (using the “reconnect” middleware).

Below is an explanation of the corresponding middlewares.

Multi-tenancy middleware

You may use the “multiTenancy” middleware when you have a single multi-tenant database. If your tenants are identified by the “customer_id” column, then you can use the following handler:

'multiTenancy.handler' => function ($operation, $tableName) {
    return ['customer_id' => 12];
},

This construct adds a filter requiring “customer_id” to be “12” to every operation (except for “create”). It also sets the column “customer_id” on “create” to “12” and removes the column from any other write operation.

NB: You may want to retrieve the customer id from the session (the “$_SESSION” variable).

Reconnect middleware

You may use the “reconnect” middleware when you have a separate database for each tenant. If the tenant has it’s own database named “customer_12”, then you can use the following handler:

'reconnect.databaseHandler' => function () {
    return 'customer_12';
},

This will make the API reconnect to the database specifying “customer_12” as the database name. If you don’t want to use the same credentials, then you should also implement the “usernameHandler” and “passwordHandler”.

NB: You may want to retrieve the database name from the session (the “$_SESSION” variable).

Prevent database scraping

You may use the “joinLimits” and “pageLimits” middleware to prevent database scraping. The “joinLimits” middleware limits the table depth, number of tables and number of records returned in a join operation. If you want to allow 5 direct direct joins with a maximum of 25 records each, you can specify:

'joinLimits.depth' => 1,
'joinLimits.tables' => 5,
'joinLimits.records' => 25,

The “pageLimits” middleware limits the page number and the number records returned from a list operation. If you want to allow no more than 10 pages with a maximum of 25 records each, you can specify:

'pageLimits.pages' => 10,
'pageLimits.records' => 25,

NB: The maximum number of records is also applied when there is no page number specified in the request.

Customization handlers

You may use the “customization” middleware to modify request and response and implement any other functionality.

'customization.beforeHandler' => function ($operation, $tableName, $request, $environment) {
    $environment->start = microtime(true);
},
'customization.afterHandler' => function ($operation, $tableName, $response, $environment) {
    return $response->withHeader('X-Time-Taken', microtime(true) - $environment->start);
},

The above example will add a header “X-Time-Taken” with the number of seconds the API call has taken.

XML middleware

You may use the “xml” middleware to translate input and output from JSON to XML. This request:

GET /records/posts/1

Outputs (when “pretty printed”):

{
    "id": 1,
    "user_id": 1,
    "category_id": 1,
    "content": "blog started"
}

While (note the “format” query parameter):

GET /records/posts/1?format=xml

Outputs:

<root>
    <id>1</id>
    <user_id>1</user_id>
    <category_id>1</category_id>
    <content>blog started</content>
</root>

This functionality is disabled by default and must be enabled using the “middlewares” configuration setting.

File uploads

File uploads are supported through the FileReader API, check out the example.

OpenAPI specification

On the “/openapi” end-point the OpenAPI 3.0 (formerly called “Swagger”) specification is served. It is a machine readable instant documentation of your API. To learn more, check out these links:

Swagger Editor can be used to view and debug the generated specification.
OpenAPI specification is a manual for creating an OpenAPI specification.
Swagger Petstore is an example documentation that is generated using OpenAPI.

Cache

There are 4 cache engines that can be configured by the “cacheType” config parameter:

TempFile (default)
Redis
Memcache
Memcached

You can install the dependencies for the last three engines by running:

sudo apt install php-redis redis
sudo apt install php-memcache memcached
sudo apt install php-memcached memcached

The default engine has no dependencies and will use temporary files in the system “temp” path.

You may use the “cachePath” config parameter to specify the file system path for the temporary files or in case that you use a non-default “cacheType” the hostname (optionally with port) of the cache server.

Types

These are the supported types with their length, category, JSON type and format:

type	length	category	JSON type	format
varchar	255	character	string
clob		character	string
boolean		boolean	boolean
integer		integer	number
bigint		integer	number
float		float	number
double		float	number
decimal	19,4	decimal	string
date		date/time	string	yyyy-mm-dd
time		date/time	string	hh:mm:ss
timestamp		date/time	string	yyyy-mm-dd hh:mm:ss
varbinary	255	binary	string	base64 encoded
blob		binary	string	base64 encoded
geometry		other	string	well-known text

Note that geometry is a non-jdbc type and thus has limited support.

Data types in JavaScript

Javascript and Javascript object notation (JSON) are not very well suited for reading database records. Decimal, date/time, binary and geometry types must be represented as strings in JSON (binary is base64 encoded, geometries are in WKT format). Below are two more serious issues described.

64 bit integers

JavaScript does not support 64 bit integers. All numbers are stored as 64 bit floating point values. The mantissa of a 64 bit floating point number is only 53 bit and that is why all integer numbers bigger than 53 bit may cause problems in JavaScript.

Inf and NaN floats

The valid floating point values ‘Infinite’ (calculated with ‘1/0’) and ‘Not a Number’ (calculated with ‘0/0’) cannot be expressed in JSON, as they are not supported by the JSON specification. When these values are stored in a database then you cannot read them as this script outputs database records as JSON.

Errors

The following errors may be reported:

Error	HTTP response code	Message
1000	404 Not found	Route not found
1001	404 Not found	Table not found
1002	422 Unprocessable entity	Argument count mismatch
1003	404 Not found	Record not found
1004	403 Forbidden	Origin is forbidden
1005	404 Not found	Column not found
1006	409 Conflict	Table already exists
1007	409 Conflict	Column already exists
1008	422 Unprocessable entity	Cannot read HTTP message
1009	409 Conflict	Duplicate key exception
1010	409 Conflict	Data integrity violation
1011	401 Unauthorized	Authentication required
1012	403 Forbidden	Authentication failed
1013	422 Unprocessable entity	Input validation failed
1014	403 Forbidden	Operation forbidden
1015	405 Method not allowed	Operation not supported
1016	403 Forbidden	Temporary or permanently blocked

1018	403 Forbidden	Only AJAX requests allowed
1019	403 Forbidden	Pagination Forbidden

The following JSON structure is used:

{
    "code":1002,
    "message":"Argument count mismatch in '1'"
}

NB: Any non-error response will have status: 200 OK

Tests

I am testing mainly on Ubuntu and I have the following test setups:

(Docker) Ubuntu 16.04 with PHP 7.0, MariaDB 10.0, PostgreSQL 9.5 (PostGIS 2.2) and SQL Server 2017
(Docker) Debian 9 with PHP 7.0, MariaDB 10.1, PostgreSQL 9.6 (PostGIS 2.3) and SQLite 3.16
(Docker) Ubuntu 18.04 with PHP 7.2, MySQL 5.7, PostgreSQL 10.4 (PostGIS 2.4) and SQLite 3.22
(Docker) Debian 10 with PHP 7.3, MariaDB 10.3, PostgreSQL 11.4 (PostGIS 2.5) and SQLite 3.27
(Docker) Ubuntu 20.04 with PHP 7.4, MySQL 8.0, PostgreSQL 12.2 (PostGIS 3.0) and SQLite 3.31
(Docker) CentOS 8 with PHP 7.4, MariaDB 10.5, PostgreSQL 12.5 (PostGIS 3.0) and SQLite 3.26

This covers not all environments (yet), so please notify me of failing tests and report your environment. I will try to cover most relevant setups in the “docker” folder of the project.

Running

To run the functional tests locally you may run the following command:

php test.php

This runs the functional tests from the “tests” directory. It uses the database dumps (fixtures) and database configuration (config) from the corresponding subdirectories.

Nginx config example

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;
    index index.php index.html index.htm index.nginx-debian.html;
    server_name server_domain_or_IP;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        try_files $fastcgi_script_name =404;
        set $path_info $fastcgi_path_info;
        fastcgi_param PATH_INFO $path_info;
        fastcgi_index index.php;
        include fastcgi.conf;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }
}

Docker tests

Install docker using the following commands and then logout and login for the changes to take effect:

sudo apt install docker.io
sudo usermod -aG docker ${USER}

To run the docker tests run “build_all.sh” and “run_all.sh” from the docker directory. The output should be:

As you can see the “run.sh” script gives you access to a prompt in a chosen the docker environment. In this environment the local files are mounted. This allows for easy debugging on different environments. You may type “exit” when you are done.

Docker image

There is a Dockerfile in the repository that is used to build an image at:

https://hub.docker.com/r/mevdschee/php-crud-api

It will be automatically build on every release. The “latest” tag points to the last release.

Docker compose

This repository also contains a docker-compose.yml file that you can install/build/run using:

sudo apt install docker-compose
docker-compose build
docker-compose up

This will setup a database (MySQL) and a webserver (Apache) and runs the application using the blog example data used in the tests.

Test the script (running in the container) by opening the following URL:

http://localhost:8080/records/posts/1

Enjoy!
