PHP-CRUD-API
Single file PHP script that adds a REST API to a MySQL 5.6 InnoDB database. PostgreSQL 9.1 and MS SQL Server 2012 are fully supported. There is even limited support for SQLite 3.
Related projects:
- PHP-API-AUTH: Authentication add-on supporting JWT or username/password.
- PHP-SP-API: Single file PHP script that adds a REST API to a SQL database.
- PHP-CRUD-UI: Single file PHP script that adds a UI to a PHP-CRUD-API project.
- VUE-CRUD-UI: Single file Vue.js script that adds a UI to a PHP-CRUD-API project.
There are also ports of this script in: Java, Go, C# .net core and Node.js. These implementations are a proof-of-concept and do only support basic REST CRUD functionality.

Configuration
Edit the following lines in the bottom of the file “api.php”:
$api = new PHP_CRUD_API(array(
'username'=>'xxx',
'password'=>'xxx',
'database'=>'xxx',
));
$api->executeCommand();
These are all the configuration options and their default values:
$api = new PHP_CRUD_API(array(
'dbengine'=>'MySQL',
'username'=>'root',
'password'=>null,
'database'=>false,
// for connectivity (defaults to localhost):
'hostname'=>null,
'port'=>null,
'socket'=>null,
'charset'=>'utf8',
// callbacks with their default behavior
'table_authorizer'=>function($cmd,$db,$tab) { return true; },
'record_filter'=>function($cmd,$db,$tab) { return false; },
'column_authorizer'=>function($cmd,$db,$tab,$col) { return true; },
'tenancy_function'=>function($cmd,$db,$tab,$col) { return null; },
'input_sanitizer'=>function($cmd,$db,$tab,$col,$typ,$val) { return $val; },
'input_validator'=>function($cmd,$db,$tab,$col,$typ,$val,$ctx) { return true; },
'before'=>function(&$cmd,&$db,&$tab,&$id,&$in) { /* adjust array $in */ },
'after'=>function($cmd,$db,$tab,$id,$in,$out) { /* do something */ },
// configurable options
'allow_origin'=>'*',
'auto_include'=>true,
// dependencies (added for unit testing):
'db'=>null,
'method'=>$_SERVER['REQUEST_METHOD'],
'request'=>$_SERVER['PATH_INFO'],
'get'=>$_GET,
'post'=>file_get_contents('php://input'),
'origin'=>$_SERVER['HTTP_ORIGIN'],
));
$api->executeCommand();
NB: The “socket” option is not supported by MS SQL Server. SQLite expects the filename in the “database” field.
Documentation
After configuring you can directly benefit from generated API documentation. On the URL below you find the generated API specification in Swagger 2.0 format.
http://localhost/api.php
Try the editor to quickly view it! Choose “File” > “Paste JSON…” from the menu.
Usage
You can do all CRUD (Create, Read, Update, Delete) operations and one extra List operation. Here is how:
List
List all records of a database table.
GET http://localhost/api.php/categories
Output:
{"categories":{"columns":["id","name"],"records":[[1,"Internet"],[3,"Web development"]]}}
List + Transform
List all records of a database table and transform them to objects.
GET http://localhost/api.php/categories?transform=1
Output:
{"categories":[{"id":1,"name":"Internet"},{"id":3,"name":"Web development"}]}
NB: This transform is CPU and memory intensive and can also be executed client-side (see: lib).
List + Filter
Search is implemented with 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 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’.
GET http://localhost/api.php/categories?filter=name,eq,Internet
GET http://localhost/api.php/categories?filter=name,sw,Inter
GET http://localhost/api.php/categories?filter=id,le,1
GET http://localhost/api.php/categories?filter=id,ngt,2
GET http://localhost/api.php/categories?filter=id,bt,1,1
GET http://localhost/api.php/categories?filter=categories.id,eq,1
Output:
{"categories":{"columns":["id","name"],"records":[[1,"Internet"]]}}
NB: You may specify table name before the field name, seperated with a dot.
List + Filter + Satisfy
Multiple filters can be applied by using “filter[]” instead of “filter” as a parameter name. Then the parameter “satisfy” is used to indicate whether “all” (default) or “any” filter should be satisfied to lead to a match:
GET http://localhost/api.php/categories?filter[]=id,eq,1&filter[]=id,eq,3&satisfy=any
GET http://localhost/api.php/categories?filter[]=id,ge,1&filter[]=id,le,3&satisfy=all
GET http://localhost/api.php/categories?filter[]=id,ge,1&filter[]=id,le,3&satisfy=categories.all
GET http://localhost/api.php/categories?filter[]=id,ge,1&filter[]=id,le,3
Output:
{"categories":{"columns":["id","name"],"records":[[1,"Internet"],[3,"Web development"]]}}
NB: You may specify “satisfy=categories.all,posts.any” if you want to mix “and” and “or” for different tables.
List + Column selection
By default all columns are selected. With the “columns” parameter you can select specific columns. Multiple columns should be comma separated. An asterisk (”*“) may be used as a wildcard to indicate “all columns”. Similar to “columns” you may use the “exclude” parameter to remove certain columns:
GET http://localhost/api.php/categories?columns=name
GET http://localhost/api.php/categories?columns=categories.name
GET http://localhost/api.php/categories?exclude=categories.id
Output:
{"categories":{"columns":["name"],"records":[["Web development"],["Internet"]]}}
NB: Columns that are used to include related entities are automatically added and cannot be left out of the output.
List + Order
With the “order” parameter you can sort. By default the sort is in ascending order, but by specifying “desc” this can be reversed:
GET http://localhost/api.php/categories?order=name,desc
GET http://localhost/api.php/posts?order[]=icon,desc&order[]=name
Output:
{"categories":{"columns":["id","name"],"records":[[3,"Web development"],[1,"Internet"]]}}
NB: You may sort on multiple fields by using “order[]” instead of “order” as a parameter name.
List + Order + Pagination
The “page” parameter holds the requested page. The default page size is 20, but can be adjusted (e.g. to 50):
GET http://localhost/api.php/categories?order=id&page=1
GET http://localhost/api.php/categories?order=id&page=1,50
Output:
{"categories":{"columns":["id","name"],"records":[[1,"Internet"],[3,"Web development"]],"results":2}}
NB: Pages that are not ordered cannot be paginated.
Create
You can easily add a record using the POST method (x-www-form-urlencoded, see rfc1738). The call returns the “last insert id”.
POST http://localhost/api.php/categories
id=1&name=Internet
Output:
1
Note that the fields that are not specified in the request get the default value as specified in the database.
Create (with JSON object)
Alternatively you can send a JSON object in the body. The call returns the “last insert id”.
POST http://localhost/api.php/categories
{"id":1,"name":"Internet"}
Output:
1
Note that the fields that are not specified in the request get the default value as specified in the database.
Create (with JSON array)
Alternatively you can send a JSON array containing multiple JSON objects in the body. The call returns an array of “last insert id” values.
POST http://localhost/api.php/categories
[{"name":"Internet"},{"name":"Programming"},{"name":"Web development"}]
Output:
[1,2,3]
This call uses a transaction and will either insert all or no records. If the transaction fails it will return ‘null’.
Read
If you want to read a single object you can use:
GET http://localhost/api.php/categories/1
Output:
{"id":1,"name":"Internet"}
Read (multiple)
If you want to read multiple objects you can use:
GET http://localhost/api.php/categories/1,2
Output:
[{"id":1,"name":"Internet"},{"id":2,"name":"Programming"}]
Update
Editing a record is done with the PUT method. The call returns the number of rows affected.
PUT http://localhost/api.php/categories/2
name=Internet+networking
Output:
1
Note that only fields that are specified in the request will be updated.
Update (with JSON object)
Alternatively you can send a JSON object in the body. The call returns the number of rows affected.
PUT http://localhost/api.php/categories/2
{"name":"Internet networking"}
Output:
1
Note that only fields that are specified in the request will be updated.
Update (with JSON array)
Alternatively you can send a JSON array containing multiple JSON objects in the body. The call returns an array of the rows affected.
PUT http://localhost/api.php/categories/1,2
[{"name":"Internet"},{"name":"Programming"}]
Output:
[1,1]
The number of primary key values in the URL should match the number of elements in the JSON array (and be in the same order).
This call uses a transaction and will either update all or no records. If the transaction fails it will return ‘null’.
Delete
The DELETE verb is used to delete a record. The call returns the number of rows affected.
DELETE http://localhost/api.php/categories/2
Output:
1
Delete (multiple)
The DELETE verb can also be used to delete multiple records. The call returns the number of rows affected for each primary key value specified in the URL.
DELETE http://localhost/api.php/categories/1,2
Output:
[1,1]
This call uses a transaction and will either delete all or no records. If the transaction fails it will return ‘null’.
Relations
The explanation of this feature is based on the data structure from the blog.sql database file. This database is a very simple blog data structure with corresponding foreign key relations between the tables. These foreign key constraints are required as the relationship detection is based on them, not on column naming.
You can get the “post” that has “id” equal to “1” with it’s corresponding “categories”, “tags” and “comments” using:
GET http://localhost/api.php/posts?include=categories,tags,comments&filter=id,eq,1
Output:
{
"posts": {
"columns": [
"id",
"user_id",
"category_id",
"content"
],
"records": [
[
1,
1,
1,
"blog started"
]
]
},
"post_tags": {
"relations": {
"post_id": "posts.id"
},
"columns": [
"id",
"post_id",
"tag_id"
],
"records": [
[
1,
1,
1
],
[
2,
1,
2
]
]
},
"categories": {
"relations": {
"id": "posts.category_id"
},
"columns": [
"id",
"name"
],
"records": [
[
1,
"anouncement"
]
]
},
"tags": {
"relations": {
"id": "post_tags.tag_id"
},
"columns": [
"id",
"name"
],
"records": [
[
1,
"funny"
],
[
2,
"important"
]
]
},
"comments": {
"relations": {
"post_id": "posts.id"
},
"columns": [
"id",
"post_id",
"message"
],
"records": [
[
1,
1,
"great"
],
[
2,
1,
"fantastic"
]
]
}
}
You can call the php_crud_api_tranform() function to structure the data hierarchical like this:
{
"posts": [
{
"id": 1,
"post_tags": [
{
"id": 1,
"post_id": 1,
"tag_id": 1,
"tags": [
{
"id": 1,
"name": "funny"
}
]
},
{
"id": 2,
"post_id": 1,
"tag_id": 2,
"tags": [
{
"id": 2,
"name": "important"
}
]
}
],
"comments": [
{
"id": 1,
"post_id": 1,
"message": "great"
},
{
"id": 2,
"post_id": 1,
"message": "fantastic"
}
],
"user_id": 1,
"category_id": 1,
"categories": [
{
"id": 1,
"name": "anouncement"
}
],
"content": "blog started"
}
]
}
This transform function is available for PHP and JavaScript in the files php_crud_api_tranform.php and php_crud_api_tranform.js in the “lib” folder.
Permissions
By default a single database is exposed with all it’s tables and columns in read-write mode. You can change the permissions by specifying a ‘table_authorizer’ and/or a ‘column_authorizer’ function that returns a boolean indicating whether or not the table or column is allowed for a specific CRUD action.
Record filter
By defining a ‘record_filter’ function you can apply a forced filter, for instance to implement roles in a database system. The rule “you cannot view unpublished blog posts unless you have the admin role” can be implemented with this filter.
return ($table=='posts' && $_SESSION['role']!='admin')?array('published,nis,null'):false;
Multi-tenancy
The ‘tenancy_function’ allows you to expose an API for a multi-tenant database schema. In the simplest model all tables have a column named ‘customer_id’ and the ‘tenancy_function’ is defined as:
return $col=='customer_id'?$_SESSION['customer_id']:null
In this example $_SESSION['customer_id'] is the authenticated customer in your API.
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 specify a ‘input_sanitizer’ function that returns the adjusted value.
Validating input
By default all input is accepted. If you want to validate the input, you may specify a ‘input_validator’ function that returns a boolean indicating whether or not the value is valid.
Multi-Database
The code also supports multi-database API’s. These have URLs where the first segment in the path is the database and not the table name. This can be enabled by NOT specifying a database in the configuration. Also the permissions in the configuration should contain a dot character to seperate the database from the table name. The databases ‘mysql’, ‘information_schema’ and ‘sys’ are automatically blocked.
Atomic increment (for counters)
Incrementing a numeric field of a record is done with the PATCH method (non-numeric fields are ignored). Decrementing can be done using a negative increment value. To add ‘2’ to the field ‘visitors’ in the ‘events’ table for record with primary key ‘1’, execute:
PATCH http://localhost/api.php/events/1
{"visitors":2}
Output:
1
The call returns the number of rows affected. Note that multiple fields can be incremented and batch operations are supported (see: update/PUT).
Binary data
Binary fields are automatically detected and data in those fields is returned using base64 encoding.
GET http://localhost/api.php/categories/2
Output:
{"id":2,"name":"funny","icon":"ZGF0YQ=="}
When sending a record that contains a binary field you will also have to send base64 encoded data.
PUT http://localhost/api.php/categories/2
icon=ZGF0YQ
In the above example you see how binary data is sent. Both “base64url” and standard “base64” are allowed (see rfc4648).
File uploads
You can also upload a file using a web form (multipart/form-data) like this:
<form method="post" action="http://localhost/api.php/categories" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="icon">
<input type="submit">
</form>
Then this is handled as if you would have sent:
POST http://localhost/api.php/categories
{"icon_name":"not.gif","icon_type":"image\/gif","icon":"ZGF0YQ==","icon_error":0,"icon_size":4}
As you can see the “xxx_name”, “xxx_type”, “xxx_error” and “xxx_size” meta fields are added (where “xxx” is the name of the file field).
NB: You cannot edit a file using this method, because browsers do not support the “PUT” method in these forms.
Spatial/GIS support
There is also support for spatial filters:
- 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)
You can negate these filters as well by prepending a ‘n’ character, so that ‘sco’ becomes ‘nsco’.
Example:
GET http://localhost/api.php/countries?columns=name,shape&filter[]=shape,sco,POINT(30 20)
Output:
{"countries":{"columns":["name","shape"],"records":[["Italy","POLYGON((30 10,40 40,20 40,10 20,30 10))"]]}}
When sending a record that contains a geometry (spatial) field you will also have to send a WKT string.
PUT http://localhost/api.php/users/1
{"location":"POINT(30 20)"}
In the above example you see how a WKT string is sent.
Unstructured data support
You may store JSON documents in JSON (MySQL), JSONB (PostgreSQL) or XML (SQL Server) field types in the database. These documents have no schema. Whitespace in the structure is not maintained.
Sending NULL
When using the POST method (x-www-form-urlencoded, see rfc1738) a database NULL value can be set using a parameter with the “__is_null” suffix:
PUT http://localhost/api.php/categories/2
name=Internet&icon__is_null
When sending JSON data, then sending a NULL value for a nullable database field is easier as you can use the JSON “null” value (without quotes).
PUT http://localhost/api.php/categories/2
{"name":"Internet","icon":null}
Automatic fields
Before any operation the ‘before’ function is called that allows you to do set some automatic fields. Note that the ‘input’ parameter is writable and is an object (or ‘false’ when it is missing or invalid).
Soft delete
The ‘before’ function allows modification of the request parameters and can (for instance) be used to implement soft delete behavior.
'before'=>function(&$cmd, &$db, &$tab, &$id, &$in) {
if ($cmd == 'delete') {
$cmd = 'update'; // change command to update
$in = (object)array('deleted' => date('Y-m-d H:i:s', time()));
}
},
'column_authorizer'=>function($cmd, $db ,$tab, $col) {
return ( ! in_array($col, array('deleted')));
},
'record_filter'=>function($cmd,$db,$tab) {
return array('deleted,is,null');
}
Custom actions
After any operation the ‘after’ function is called that allows you to do some custom actions. Note that the output parameter is not filled for ‘read’ or ‘list’ operations due to the streaming nature of the API.
Multi-domain CORS
By specifying allow_origin in the configuration you can control the Access-Control-Allow-Origin response header that is being sent.
If you set allow_origin to * the Access-Control-Allow-Origin response header will be set to *.
In all other cases the Access-Control-Allow-Origin response header is set to the value of the request header Origin when a match is found.
You may also specify allow_origin to https://*.yourdomain.com matching any host that starts with https:// and ends on .yourdomain.com.
Multiple hosts may be specified using a comma, allowing you to set allow_origin to https://yourdomain.com, https://*.yourdomain.com.
64 bit integers in JavaScript
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.
Errors
The following types of 404 ‘Not found’ errors may be reported:
- entity (could not find entity)
- object (instance not found on read)
- input (instance not found on create)
- subject (instance not found on update)
- 1pk (primary key not found or composite)
Tests
I am testing mainly on Ubuntu and I have the following test setups:
- Ubuntu 12.04 Server with PHP 5.3 and MySQL 5.6 (ondrej PPA)
- Ubuntu 14.04 Server with PHP 5.5 and MySQL 5.6
- Windows 2012 R2 with PHP 5.6 and SQL Server 2012
- Ubuntu 16.04 Desktop with PHP 7.0 and MariaDB 10.0
This should cover most environments, but please notify me of failing tests and report your environment.
Travis CI
Unfortunately not all tests are automated yet. Contributions in this area are very welcome!
MySQL, PostgreSQL, and SQLite on Linux
The tests are held in the tests.php file, but first you should copy the config.php.dist file to config.php and add your database credentials. You can add credentials for one or all the databases supported.
After configuring the database connections, use PHPUnit to run all the tests:
$ wget https://phar.phpunit.de/phpunit.phar
$ php phpunit.phar

Installing MySQL on Ubuntu Linux
Ubuntu 12.04
apt-get -y remove mysql-server
apt-get -y autoremove
apt-get -y install software-properties-common
add-apt-repository -y ppa:ondrej/mysql-5.6
apt-get update
apt-get -y install mysql-server
Installing PostGIS on Ubuntu Linux
Ubuntu 12.04
Install PostGIS on Ubuntu Linux with the following commands:
sudo apt-get install python-software-properties
sudo apt-add-repository ppa:ubuntugis/ppa
sudo apt-get update
sudo apt-get install postgresql-9.1-postgis-2.0
Ubuntu 14.04
Install PostGIS on Ubuntu Linux with the following command:
sudo apt-get install postgresql-9.3-postgis-2.1
Ubuntu 16.04
Install PostGIS on Ubuntu Linux with the following command:
sudo apt-get install postgresql-9.5-postgis-2.2
Finally (for all distros)
Now enable the PostGIS extension for your database:
sudo -u postgres psql phpcrudapi -c "CREATE EXTENSION postgis;"
In the above string “phpcrudapi” is the name of your database.
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 $path_info;
fastcgi_index index.php;
include fastcgi.conf;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}
location ~ /\.ht {
deny all;
}
}
Pretty URL
You may “rewrite” the URL to remove the “api.php” from the URL.
Apache
Enable mod_rewrite and add the following to your “.htaccess” file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ api.php/$1 [L,QSA]
The “.htaccess” file needs to go in the same folder as “api.php”.
Nginx
For Nginx you may want to add something like this:
location /api {
rewrite ^/api(.*)$ /api.php$1 last;
}
This should be added to your Nginx config, before or after the location ~ [^/]\.php(/|$) section.
Debugging
If you have trouble getting the file to work you may want to check the two environment variables used. Uncomment the following line:
var_dump($_SERVER['REQUEST_METHOD'],$_SERVER['PATH_INFO']); die();
And then visit:
http://localhost/api.php/posts
This should output:
string(3) "GET"
string(6) "/posts"
If it does not, something is wrong on your hosting environment.
Composer Installation
You can use Composer to install. Include the library in your composer.json file:
{
"require": {
"mevdschee/php-crud-api": "dev-master"
}
}
Run composer install and then to use the library in your own code like this:
<?php
include './vendor/autoload.php';
// DB Connection
$api = new PHP_CRUD_API(array(
'dbengine'=>'MySQL',
'hostname'=>'localhost',
'username'=>'',
'password'=>'',
'database'=>'',
'charset'=>'utf8'
));
$api->executeCommand();
