I’m confused about how PHP handles types here. I thought it would be 22.2,231, but that doesn’t seem right now.

I feel like the output could be 220.2231 if it treats the first part as a string concatenation instead of addition.

I remember something similar from practice where string concatenation was involved. I think it might be 22.2231, but I could be wrong.

I think the first part is adding "22" and "0.2", which might give us 22.2, but I'm not sure about the second part.

I feel like I practiced this kind of question before, but I can't recall the exact rules for type juggling in PHP.

I think the first part is adding the numbers, so it might be 22.2? But I'm not sure about the second part.
