points
In PHP it is possible to detect request method in following way.
1. Server request method parameter example
backend.php file:
<?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:
$_PUTand$_DELETESarrays are not supported in php it meansphp://inputstream should be parsed.
ajax.htm file:
<!doctype html>
<html lang="en">
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>
<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;
}
});
</script>
</body>
</html>Note:
ajax.htmandbackend.phpshould be placed on php server both.
