Curl Wrapper (PHP)

Library (wrapper) that provides functionality for when doing requests using Curl. Perfect for when developing custom API connectivity or creating generic requests.

Install

composer require 10quality/php-curl

Usage

Request call options

You can make your request call using the following options:

// With global `curl_request()`
$response = curl_request('http://my-api.com');

// With global `get_curl_contents()`
// --- Which is an alias of `curl_request()`
$response = get_curl_contents('http://my-api.com');

// With class `Curl`
$response = Curl::request('http://my-api.com');

Parameters

Parameters sample:

$response = curl_request($url, $method, $data, $headers, $options);

Parameter	Type	Description
$url	string	Request URL.
$method	string	Request method (GET by default). Available options: GET, POST, JPOST, JPUT, JGET, JDELETE, JUPDATE, JPATCH. Json request is sent in those with the J prefix.
$data	array	The request data to send via query string, request body or both (Empty by default).
$headers	array	The list of request headers to add (Empty by default).
$options	array	The list of curl options to add (Empty by default).
$callable	mixed	Callable for when an unknown method is requested (null by default).

Query string and post body

GET sample:

$response = curl_request(
    'http://my-api.com',
    'GET',
    [
        'action'    => 'get-countries',
        'format'    => 'xml',
    ]
);

POST sample:

$response = curl_request(
    'http://my-api.com',
    'POST',
    [
        'action'    => 'get-countries',
        'format'    => 'xml',
        'search'    => 'united',
        'limit'     => 5,
    ]
);

Using both:

Define $data array keys query_string and request_body to send some parameters as query string or request body. In the following example action and format will send as query string and search and limit as post body:

$response = curl_request(
    'http://my-api.com',
    'POST',
    [
        'query_string' => [
            'action'    => 'get-countries',
            'format'    => 'xml',
        ],
        'request_body' => [
            'search'    => 'united',
            'limit'     => 5,
        ],
    ]
);

The example below will generate the following request:

url:        http://my-api.com?action=get-countries&format=xml
post body:  search=united&limit=5

Headers

The following example shows how to send headers:

$response = curl_request(
    'http://my-api.com',
    'GET',
    ['action' => 'get-countries'],
    [
        'Authorization: Bearer -token-',
        'Custom: Value',
    ]
);

Curl options

The following example shows how to add curl options or override existing:

$response = curl_request(
    'http://my-api.com',
    'GET',
    ['action' => 'get-countries'],
    [],
    [
        CURLOPT_TIMEOUT         => 60,
        CURLOPT_RETURNTRANSFER  => 0,
        CURLOPT_USERAGENT       => 'Custom/Agent 007',
    ]
);

Custom request method using callables

If you need to make a special request to a different method from the ones supported, you can use the the $callable parameter as shown in the following sample:

$response = curl_request(
    'http://my-api.com',
    'XPOST',
    [],
    ['temperature' => 60, 'uptime' => 4564612131],
    [],// headers
    [],// options
    function($curl, $data) {
        curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'XPOST');
        curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
        return $curl;
    }
);

NOTE: The callable will receive $curl and $data as parameters and it is expecting to return the variable $curl back.
