PHP - Diffrentiating between GET and POST request

The way I have PHP set up is that everything goes to a central file called Router. the router gets a parameter action and calls that method.

In Node.js, you can have get and post versions of the same method. I was wondering, is something like this possbile in PHP?

Basically I would like this to happen:

Have an add method.

Page 1 has the add button. The add button goes to the form that needs to be filled out to add an item - a get request. Upon clicking, the add method is called.

Page 2 has another add button. The add button now inserts using form data and adds an item - a post request.

Now, both call the same method, but in the file a get version of the method is defined and post version of the method is defined.

Was wondering if this is possible without having two methods with different names.

You can use $_SERVER['REQUEST_METHOD'] to determine whether it is GET or POST. A primitive attempt might look like this:

 function handle_request() {
   $action = $_REQUEST['action'];
   $verb = tolower($_SERVER['REQUEST_METHOD']);
   // create string representation of the function to call, eg. post_add, get_add
   call_user_func( $verb.'_.'$action, $_REQUEST);
   }

 }

If you do not wish to name the function differently:

function add() {
  if (tolower($_SERVER['REQUEST_METHOD') == 'post') {
    // run the post version
  } else {
    // run the get version
  }
}

Try to use $_REQUEST. It is universal replacement for $_POST or $_GET.
