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);
