Requirements

This library is supported by PHP versions 7.0 or higher.

IMPORTANT: Version 2.x does not support version 1.x of this library.

IMPORTANT: Version 1.x has been considered obsolete, but if you want to use it for 5.6 versions of PHP you can have a look at its documentation.

Installation

The preferred way to install this extension is through Composer.

To install PHP Request library, simply:

$ composer require josantonius/request

The previous command will only install the necessary files, if you prefer to download the entire source code you can use:

$ composer require josantonius/request --prefer-source

You can also clone the complete repository with Git:

$ git clone https://github.com/Josantonius/php-request.git

Or install it manually:

Download Request.php and Validate.php:

$ wget https://raw.githubusercontent.com/Josantonius/php-request/master/src/Request.php

$ wget https://raw.githubusercontent.com/Josantonius/php-validate/master/src/Validate.php

Available Methods

Available methods in this library:

- Check if it's a GET request:

Request::isGet();

# Return (boolean)

- Check if it's a POST request:

Request::isPost();

# Return (boolean)

- Check if it's a PUT request:

Request::isPut();

# Return (boolean)

- Check if it's a DELETE request:

Request::isDelete();

# Return (boolean)

- Get request params.

For PUT and DELETE requests, the content type will be checked to correctly obtain the data received in the request.

Quick Start

To use this library with Composer:

require __DIR__ . '/vendor/autoload.php';

use Josantonius\Request\Request;

Or If you installed it manually, use it:

require_once __DIR__ . '/Request.php';
require_once __DIR__ . '/Validate.php';

use Josantonius\Request\Request;
use Josantonius\Validate\Validate;

Usage

For the examples it will be simulated that the following data is received in the request:

Example data received in the request:

'user_name' => 'John'
'user_surname' => 'Doe'
'user_age' => 35
'user_rating' => 8.5
'user_ip' => '89.58.54.188'
'user_website' => 'http://www.site.com/'
'user_email' => '[email protected]'
'user_address' => [
  'street' => 'unknown'
  'locality' => 'Seville'
  'country' => 'Spain'
]
'is_active' => true

Example of use for this library:

- Check if it's a GET request:

Request::isGet(); // true or false

- Check if it's a POST request:

Request::isPost(); // true or false

- Check if it's a PUT request:

Request::isPut(); // true or false

- Check if it's a DELETE request:

Request::isDelete(); // true or false

- Access to the parameters of the request.

$_GET = Request::input('GET');

$_POST = Request::input('POST');

$_PUT = Request::input('PUT');

$_DELETE = Request::input('DELETE');

Returns an anonymous function that will return the Request object when it's called.

- As array:

- Get and sanitize all data and return them as array:

$array = $_GET()->asArray();

$array = $_POST()->asArray();

$array = $_PUT()->asArray();

$array = $_DELETE()->asArray();

var_dump($array);

/*
array(9) {
  ["user_name"]=>
  string(4) "John"
  ["user_surname"]=>
  string(3) "Doe"
  ["user_age"]=>
  int(35)
  ["user_rating"]=>
  float(8.5)
  ["user_ip"]=>
  string(12) "89.58.54.188"
  ["user_website"]=>
  string(20) "http://www.site.com/"
  ["user_email"]=>
  string(13) "[email protected]"
  ["user_address"]=>
  array(3) {
    ["street"]=>
    string(7) "unknown"
    ["locality"]=>
    string(7) "Seville"
    ["country"]=>
    string(5) "Spain"
  }
  ["is_active"]=>
  bool(true)
}
*/

• Example data received in the request

- Obtain, sanitize all data and return them as array and filter each value according to the data type:

$filters = [
    'user_name' => 'string',

    'is_online' => 'boolean'
];

$array = $_GET()->asArray($filters);

$array = $_POST()->asArray($filters);

$array = $_PUT()->asArray($filters);

$array = $_DELETE()->asArray($filters);

var_dump($array['user_name']); // string(4) "John"

var_dump($array['user_age']); // string(2) "35" (although an integer is received, it's returned as a string)

var_dump($array['user_age']); // NULL (doesn't exist, the default value is returned)

• Example data received in the request

- Obtain, sanitize all data and return them as array, filter each value according to the data type and specify a value for each key when it's wrong:

$filters = [
    'user_rating' => 'float',

    'is_online' => 'boolean'
];

$array = $_GET()->asArray($filters, '');

$array = $_POST()->asArray($filters, '');

$array = $_PUT()->asArray($filters, '');

$array = $_DELETE()->asArray($filters, '');

var_dump($array['user_rating']); // float(8.5)

var_dump($array['is_active']); // bool(true)

var_dump($array['is_online']); // string(0) "" (doesn't exist, the default value is returned)

- As object:

- Get and sanitize all data and return them as object:

$object = $_GET()->asObject();

$object = $_POST()->asObject();

$object = $_PUT()->asObject();
