Question

I’m trying to add some error checking inside my PHP script. Is it valid to do this:

if (!mkdir($dir, 0)) {
    $res->success = false;
    $res->error = 'Failed to create directory';
    echo json_encode($res);
    die;
}

Is there a better way to exit the script after encountering an error like this?

Answer 1

That looks fine to me.

You can even echo data in the die like so:

if (!mkdir($dir, 0)) {
    $res->success = false;
    $res->error = 'Failed to create directory';
    die(json_encode($res));
}
