Requirements

This library is supported by PHP 7.4.

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.

The content types compatible with this library are:

• application/atom+xml
• text/html
• text/plain
• application/json
• application/javascript
• multipart/form-data
• application/x-www-form-urlencoded

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' => 'john@site.com'
'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"]=>
