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

By using
$_SERVER['REQUEST_METHOD']
Example
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// The request is using the POST method
}
For more details please see the documentation for the $_SERVER variable.
REST in PHP can be done pretty simple. Create http://example.com/test.php (outlined below). Use this for REST calls, e.g. http://example.com/test.php/testing/123/hello. This works with Apache and Lighttpd out of the box, and no rewrite rules are needed.
<?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;
}
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;
}
?>
It is valuable to additionally note, that PHP will populate all the $_GET parameters even when you send a proper request of other type.
Methods in above replies are completely correct, however if you want to additionaly check for GET parameters while handling POST, DELETE, PUT, etc. request, you need to check the size of $_GET array.
TL;DR
The "native source of true" is the $_SERVER global variable. The request Method
is saved under the key "REQUEST_METHOD".
Check the $_SERVER array
$_SERVER['REQUEST_METHOD']
PHP Methods
But you can use a lot of workarounds to get the Method. Like filter_input:
filter_input(INPUT_SERVER, 'REQUEST_METHOD', FILTER_SANITIZE_ENCODED);
Libs Or you use external libs like:
Symfony\Component\HttpFoundation\Request\Zend\Http\PhpEnvironment\Request
Conclusion
But the easiest way would be to use: $_SERVER['REQUEST_METHOD'].
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>
