How can I detect which request type was used (GET, POST, PUT or DELETE) in PHP?
By using
$_SERVER['REQUEST_METHOD']
if ($_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;
}
Detecting the HTTP method or so calledREQUEST METHOD
can be done using the following code snippet.
$method = $_SERVER['REQUEST_METHOD'];
if ($method == 'POST'){
// Method is POST
} elseif ($method == 'GET'){
// Method is GET
} elseif ($method == 'PUT'){
// Method is PUT
} elseif ($method == 'DELETE'){
// Method is DELETE
} else {
// Method unknown
}
You could also do it using aswitch
if you prefer this over theif-else
statement.
If a method other thanGET
orPOST
is required in an HTML form, this is often solved using a hidden field in the form.
<!-- DELETE method -->
<form action='' method='POST'>
<input type="hidden" name'_METHOD' value="DELETE">
</form>
<!-- PUT method -->
<form action='' method='POST'>
<input type="hidden" name'_METHOD' value="PUT">
</form>
For more information regarding HTTP methods I would like to refer to the following StackOverflow question:
You can usegetenv
function and don't have to work with a$_SERVER
variable:
getenv('REQUEST_METHOD');
More info:
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);
Since this is about REST, just getting the request method from the server is not enough. You also need to receive RESTful route parameters. The reason for separating RESTful parameters and GET/POST/PUT parameters is that a resource needs to have its own unique URL for identification.
Here's one way of implementing RESTful routes in PHP using Slim:
https://github.com/codeguy/Slim
$app = new \Slim\Slim();
$app->get('/hello/:name', function ($name) {
echo "Hello, $name";
});
$app->run();
And configure the server accordingly.
Here's another example using AltoRouter:
https://github.com/dannyvankooten/AltoRouter
$router = new AltoRouter();
$router->setBasePath('/AltoRouter'); // (optional) the subdir AltoRouter lives in
// mapping routes
$router->map('GET|POST','/', 'home#index', 'home');
$router->map('GET','/users', array('c' => 'UserController', 'a' => 'ListAction'));
$router->map('GET','/users/[i:id]', 'users#show', 'users_show');
$router->map('POST','/users/[i:id]/[delete|update:action]', 'usersController#doAction', 'users_do');
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;
}
?>
$request = new \Zend\Http\PhpEnvironment\Request();
$httpMethod = $request->getMethod();
In this way you can also achieve in zend framework 2 also. Thanks.
It is Very Simple just use $_SERVER['REQUEST_METHOD'];
Example:
<?php
$method = $_SERVER['REQUEST_METHOD'];
switch ($method) {
case 'GET':
//Here Handle GET Request
break;
case 'POST':
//Here Handle POST Request
break;
case 'DELETE':
//Here Handle DELETE Request
break;
case 'PUT':
//Here Handle PUT Request
break;
}
?>
It is valuable to additionally note, that PHP will populate all the$_GET
parameters even when you send a proper request of other type.
Methods in above replies are completely correct, however if you want to additionaly check forGET
parameters while handlingPOST
,DELETE
,PUT
, etc. request, you need to check the size of$_GET
array.
The "native source of true" is the$_SERVER
global variable. The request Method
is saved under the key "REQUEST_METHOD".
Check the $_SERVER array
$_SERVER['REQUEST_METHOD']
PHP Methods
But you can use a lot of workarounds to get the Method. Like filter_input:filter_input(INPUT_SERVER, 'REQUEST_METHOD', FILTER_SANITIZE_ENCODED);
Libs Or you use external libs like:
Symfony\Component\HttpFoundation\Request
\Zend\Http\PhpEnvironment\Request
But the easiest way would be to use:$_SERVER['REQUEST_METHOD']
.
When a method was requested, it will have anarray
. So simply check withcount()
.
$m=['GET'=>$_GET,'POST'=>$_POST];
foreach($m as$k=>$v){
echo count($v)?
$k.' was requested.':null;
}
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 $request_method;
}
This above code will work withREST calls
and will also work withhtml form
<form method="post">
<input name="_method" type="hidden" value="delete" />
<input type="submit" value="Submit">
</form>
You can get any query string data i.ewww.example.com?id=2&name=r
You must get data using$_GET['id']
or$_REQUEST['id']
.
Post data means like form<form action='' method='POST'>
you must use$_POST
or$_REQUEST
.
