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

Detecting the HTTP method or so called REQUEST METHOD can be done using the following code snippet.

$method = $_SERVER['REQUEST_METHOD'];
if ($method == 'POST'){
    // Method is POST
} elseif ($method == 'GET'){
    // Method is GET
} elseif ($method == 'PUT'){
    // Method is PUT
} elseif ($method == 'DELETE'){
    // Method is DELETE
} else {
    // Method unknown
}

You could also do it using a switch if you prefer this over the if-else statement.

If a method other than GET or POST is required in an HTML form, this is often solved using a hidden field in the form.
