By default, PHP Curl supports GET and POST requests. It is possible to also send custom requests, such as DELETE, PUT or PATCH (or even non-standard methods) using the CURLOPT_CUSTOMREQUEST parameter.

$method = 'DELETE'; // Create a DELETE request

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
$content = curl_exec($ch);
curl_close($ch);
