In this article, we would like to show you how to detect the request method in PHP.

Server request method parameter example

Edit

backend.php file:

xxxxxxxxxx
 
<?php
​
    $method = $_SERVER['REQUEST_METHOD'];
​
    function parseInput()
    {
        $data = file_get_contents("php://input");
​
        if($data == false)
            return array();
​
        parse_str($data, $result);
​
        return $result;
    }
​
    switch ($method)
    {
        case 'GET':
            echo "GET request method\n";
            echo print_r($_GET, true);
            break;
        case 'POST':
            echo "POST request method\n";
            echo print_r($_POST, true);
            break;
        case 'PUT':
            $_PUT = parseInput();
​
            echo "PUT request method\n";
            echo print_r($_PUT, true);
            break;
        case 'DELETE':
            $_DELETE = parseInput();
​
            echo "DELETE request method\n";
            echo print_r($_DELETE, true);
            break;
        default:
            echo "Unknown request method.";
            break;
    }

Note: $_PUT and $_DELETES arrays are not supported in php it means php://input stream should be parsed.

ajax.htm file:

xxxxxxxxxx
 
<!doctype html>
<html lang="en">
<head>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

<body>
<pre id="response"></pre>
<script>
​
    var handle = document.getElementById('response');
​
    $.ajax({
        type: 'GET', // 'POST', 'PUT', 'DELETE'
        url: '/backend.php',
        data: {
            name: 'John',
            age: 25
        },
        success: function (data) {
            handle.innerHTML = 'Response:\n' + data;
        },
        error: function(error) {
            handle.innerText = 'Error: ' + error.status;
        }
    });
