Detecting request type in PHP (GET, POST, PUT or DELETE)

Question

How can I detect which request type was used (GET, POST, PUT or DELETE) in PHP?

Answer 1

I used this code. It should work.

function get_request_method() {
    $request_method = strtolower($_SERVER['REQUEST_METHOD']);

    if($request_method != 'get' && $request_method != 'post') {
        return $request_method;
    }

    if($request_method == 'post' && isset($_POST['_method'])) {
        return strtolower($_POST['_method']);
    }

    return $request_method;
}

This above code will work with REST calls and will also work with html form
