I’m confused. Could it be F? Nothing happens?

I feel like it’s definitely D. The function needs $x2.

But $x2 is missing, so it should warn us.

I’m leaning towards A. It returns 0 since $x1 is 10.

But isn’t D more accurate? It warns about $x2.

I’m leaning towards option D, but I’m not completely confident since I can’t recall how PHP handles default values in this context.

This reminds me of a practice question where a missing parameter caused a warning. I feel like that might happen here too.

I remember something about default parameters, but I’m confused if $x2 being unset will cause a warning or not.

I think the function will return 0 since $x2 is passed as 0, but I'm not entirely sure about the default value of $x1.
