A basic CURL wrapper for PHP (see for more information about the libcurl extension for PHP)


Add this line to your composer.json:

"require": {
    // ...
    "shuber/curl": "*"



Composer should autoload the package, so you just need to include it

use shuber\Curl\Curl;

$curl = new Curl;

Performing a Request

The Curl object supports 5 types of requests: HEAD, GET, POST, PUT, and DELETE. You must specify a url to request and optionally specify an associative array or string of variables to send along with it.

$response = $curl->head($url, $vars = array());
$response = $curl->get($url, $vars = array()); # The Curl object will append the array of $vars to the $url as a query string
$response = $curl->post($url, $vars = array());
$response = $curl->put($url, $vars = array());
$response = $curl->delete($url, $vars = array());

To use a custom request methods, you can call the request method:

$response = $curl->request('YOUR_CUSTOM_REQUEST_TYPE', $url, $vars = array());

All of the built in request methods like put and get simply wrap the request method. For example, the post method is implemented like:

function post($url, $vars = array()) {
    return $this->request('POST', $url, $vars);


$response = $curl->get('');

# The Curl object will append '&some_variable=some_value' to the url
$response = $curl->get('', array('some_variable' => 'some_value'));

$response = $curl->post('', array('title' => 'Test', 'body' => 'This is a test'));

All requests return a CurlResponse object (see below) or false if an error occurred. You can access the error string with the $curl->error() method.

The CurlResponse Object

A normal CURL request will return the headers and the body in one response string. This class parses the two and places them into separate properties.

For example

$response = $curl->get('');
echo $response->body; # A string containing everything in the response except for the headers
print_r($response->headers); # An associative array containing the response headers

Which would display something like

Some more html...

    [Http-Version] => 1.0
    [Status-Code] => 200
    [Status] => 200 OK
    [Cache-Control] => private
    [Content-Type] => text/html; charset=ISO-8859-1
    [Date] => Wed, 07 May 2008 21:43:48 GMT
    [Server] => gws
    [Connection] => close

The CurlResponse class defines the magic __toString() method which will return the response body, so echo $response is the same as echo $response->body

Cookie Sessions

By default, cookies will be stored in a file called curl_cookie.txt. You can change this file's name by setting it like this

$curl->cookie_file = 'some_other_filename';

This allows you to maintain a session across requests

Basic Configuration Options

You can easily set the referer or user-agent

$curl->referer = '';
$curl->user_agent = 'some user agent string';

You may even set these headers manually if you wish (see below)

Setting Custom Headers

You can set custom headers to send with the request

$curl->headers['Host'] = 12.345.678.90;
$curl->headers['Some-Custom-Header'] = 'Some Custom Value';

Setting Custom CURL request options

By default, the Curl object will follow redirects. You can disable this by setting:

$curl->follow_redirects = false;

You can set/override many different options for CURL requests (see the curl_setopt documentation for a list of them)

# any of these will work
$curl->options['AUTOREFERER'] = true;
$curl->options['autoreferer'] = true;
$curl->options['CURLOPT_AUTOREFERER'] = true;
$curl->options['curlopt_autoreferer'] = true;


Uses ztest, simply download it to path/to/curl/test/ztest (or anywhere else in your php include_path)

Then run test/runner.php
