Parse error: syntax error, unexpected '?' error

Question

picture of codeI have this code:

<?php if(isset($_GET["update"])){
        $id = $_GET["id"] ?? null;

        $where = array("id"=>$id);
        $row = $obj->select_record("medicines",$where);

        ?>

I get this :

Parse error: syntax error, unexpected '?' in C:\wamp\www\New folder\index.php on line 42

Is there any alternative to the above code?

You should use:

 $id = $_GET['id']?$_GET['id']:null;
