I am watching a video about PHP form submit, it mentions this method 

if ($_SERVER["REQUEST_METHOD"] == "POST") {
/* code handle the form date */
}

I don't know why we should use that? Can someone explain for me? Thanks!

There are various methods of from submission like POST, GET, PUT, DELETE.

$_SERVER['REQUEST_METHOD'] holds the name of the method for a form submission. If you want to restrict your form processing only form POST type request, then you need to put that check.

$_SERVER['REQUEST_METHOD']

contains the request method. It is used to check request method.This variable also says if the request is a 'GET', 'HEAD', 'POST' or 'PUT' request.
