        $val === null ||
        $val === false ||

    }
    
    return false;

So...why is it a so 'tremendous slow function'?

I did not mean the == (why 3?) operator was slow, I meant empty() was slow. And next to that, like you said, it doesn't check all sorts of vars and arrays. You can check if the var contains something but it won't work on an array.
