INPUT_GET instead of $_GET

Hello everyone, If you had a trouble about $_GET You should use INPUT_GET. I am using NetBeans IDE and I took an error which is " Do Not Acess Superglobal $_Get Array Directly". Problem solve is in PHP docemantation:

http://php.net/manual/en/filter.constants.php

if (filter_input(INPUT_GET, "cat") == "books") { $pageTitle = "Books"; }elseif(filter_input(INPUT_GET, "cat") == "movies") { $pageTitle = "Movies"; }elseif (filter_input(INPUT_GET, "cat") == "music") { $pageTitle = "Musics"; }

You can use isset() or empty() to validate the superglobal such as

<?php
if(isset($_GET) && !empty($_GET)){
    // do something
} else {
   header("Location: index.php");
}
?>

I think the code examlple above will not show up the "Do Not Access Superglobal $Get Array Directly" error message :D
