在core php中，你可以这样做:

<?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;
}


?>

我们还可以使用input_filter来检测请求方法，同时通过输入环境保护来提供安全性。

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

通过使用

$_SERVER['REQUEST_METHOD']

例子

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
     // The request is using the POST method
}

要了解更多细节，请参阅$_SERVER变量的文档。

当一个方法被请求时，它将有一个数组。因此，只需使用count()进行检查。

$m=['GET'=>$_GET,'POST'=>$_POST];
foreach($m as$k=>$v){
    echo count($v)?
    $k.' was requested.':null;
}

你可以使用getenv函数，而不必使用$_SERVER变量:

getenv('REQUEST_METHOD');

PHP中的REST可以非常简单地实现。创建http://example.com/test.php(如下所示)。将此用于REST调用，例如http://example.com/test.php/testing/123/hello。这与Apache和Lighttpd一起开箱即用，不需要重写规则。

<?php
$method = $_SERVER['REQUEST_METHOD'];
$request = explode("/", substr(@$_SERVER['PATH_INFO'], 1));

switch ($method) {
  case 'PUT':
    do_something_with_put($request);  
    break;
  case 'POST':
    do_something_with_post($request);  
    break;
  case 'GET':
    do_something_with_get($request);  
    break;
  default:
    handle_error($request);  
    break;
}
