Is there a php way on how to check if the url is use now?

for example I have

http://site.com/login.php?action=submit

using isset($_GET[action])

we can check that action exists in the url

but how can I check if

login.php

is the one that is active url?

Something like this:

if ( '/login.php' == $_SERVER['REQUEST_URI'] ) {
    // This is login.php
} else {
    // This is not login.php
}
