Question

When I fill variables, can I do something like this?:

$type = isset( $_GET['type'] ) ?  $_GET['type'] : die();

By doing so, if ‘type’ is not in the request, my function will exit. Is this the correct way to use die()?

Answer 1

If you just want your function to exit, use return. However, it’s not an expression, so you’ll need to change it to an if statement:

if(!isset($_GET['type'])) {
    return;
}

$type = $_GET['type'];

If you do want your whole page to stop execution, then yes, that’s correct (but I’d still use an if for clarity).
