Dublicate code

<?php
if (isset ($_GET['name'])) {
    $name = $_GET['name'];
}  
/* as the same if statement is within the function itself now
    the code snippet above is obsolete, isn' t it?
    If it is redundant, please update the code example so that others don' t get confused.
    Otherwise I appreciate any hint why the dublicate code is needed here.
   Thank you.
*/

function greeting() {
        if (isset ($_GET['name'])) {
            $name = $_GET['name'];
            echo "Hello, " . $name;
        }
}
greeting();
?>

Hi there, devis ! I agree with you about the duplicate code. I'm not sure if it was included for emphasis, but I will bring it up with the education team. Thank you for bringing this to my attention! :smiley:

Hi Jennifer, it's still here! And in the quiz as well. Also confused me. Did you get an answer as to why it's added twice?

Why is isset doubled? To make it double safe?
