$_GET error

I did everything in video but I couldn't get specific product details. I'm using Netbeans and it says "Do not access superglobal $_GET array directly". What should I do?

'''if (isset($_GET["id"])){ $id = $_GET["id"]; if (isset($catalog[$id])) { $item = $catalog[$id]; }
}'''

I tried this;

'''filter_input(INPUT_GET,"id")'''

but this time isset giving an error; "Cannot use isset() on the result of an expression (you can use "null !== expression" instead"
