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

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

In core php you can do like this :

<?php

$method = $_SERVER['REQUEST_METHOD'];

switch ($method) {
  case 'GET':
    //Here Handle GET Request
    echo 'You are using '.$method.' Method';
    break;
  case 'POST':
    //Here Handle POST Request
    echo 'You are using '.$method.' Method';
    break;
  case 'PUT':
    //Here Handle PUT Request
    echo 'You are using '.$method.' Method';
    break;
  case 'PATCH':
    //Here Handle PATCH Request
    echo 'You are using '.$method.' Method';
    break;
  case 'DELETE':
    //Here Handle DELETE Request
    echo 'You are using '.$method.' Method';
    break;
  case 'COPY':
      //Here Handle COPY Request
      echo 'You are using '.$method.' Method';
      break;

  case 'OPTIONS':
      //Here Handle OPTIONS Request
      echo 'You are using '.$method.' Method';
      break;
  case 'LINK':
      //Here Handle LINK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'UNLINK':
      //Here Handle UNLINK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'PURGE':
      //Here Handle PURGE Request
      echo 'You are using '.$method.' Method';
      break;
  case 'LOCK':
      //Here Handle LOCK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'UNLOCK':
      //Here Handle UNLOCK Request
      echo 'You are using '.$method.' Method';
      break;
  case 'PROPFIND':
      //Here Handle PROPFIND Request
      echo 'You are using '.$method.' Method';
      break;
  case 'VIEW':
      //Here Handle VIEW Request
      echo 'You are using '.$method.' Method';
      break;
  Default:
    echo 'You are using '.$method.' Method';
  break;
}

We can also use the input_filter to detect the request method while also providing security through input sanitation.

$request = filter_input(INPUT_SERVER, 'REQUEST_METHOD', FILTER_SANITIZE_ENCODED);

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

<form method="post">
    <input name="_method" type="hidden" value="delete" />
    <input type="submit" value="Submit">
</form>
