This library provides an object-oriented and dependency free wrapper of the PHP cURL extension.

If you have questions or problems with installation or usage create an Issue.

Installation

In order to install this library via composer run the following command in the console:

composer require curl/curl

Usage examples

A few example for using CURL with get:

$curl = (new Curl\Curl())->get('http://www.example.com/');
if ($curl->isSuccess()) {
    // do something with response
    var_dump($curl->response);
}
// ensure to close the curl connection
$curl->close();

Or with params, values will be encoded with PHP_QUERY_RFC1738:

$curl = (new Curl\Curl())->get('http://www.example.com/search', [
    'q' => 'keyword',
]);

An example using post

$curl = new Curl\Curl();
$curl->post('http://www.example.com/login/', [
    'username' => 'myusername',
    'password' => 'mypassword',
]);

An exampling using basic authentication, remove default user agent and working with error handling

$curl = new Curl\Curl();
$curl->setBasicAuthentication('username', 'password');
$curl->setUserAgent('');
$curl->setHeader('X-Requested-With', 'XMLHttpRequest');
$curl->setCookie('key', 'value');
$curl->get('http://www.example.com/');

if ($curl->error) {
    echo $curl->error_code;
} else {
    echo $curl->response;
}

var_dump($curl->request_headers);
var_dump($curl->response_headers);

SSL verification setup:

$curl = new Curl\Curl();
$curl->setOpt(CURLOPT_RETURNTRANSFER, TRUE);
$curl->setOpt(CURLOPT_SSL_VERIFYPEER, FALSE);
$curl->get('https://encrypted.example.com/');

Example access to curl object:

curl_set_opt($curl->curl, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1');
curl_close($curl->curl);

Example of downloading a file or any other content

$curl = new Curl\Curl();
// open the file where the request response should be written
$file_handle = fopen($target_file, 'w+');
// pass it to the curl resource
$curl->setOpt(CURLOPT_FILE, $file_handle);
// do any type of request
$curl->get('https://github.com');
// disable writing to file
$curl->setOpt(CURLOPT_FILE, null);
// close the file for writing
fclose($file_handle);
