Don't let PHP be the last language you code after other languages at the end of the day.

Yeah, you would think it's using the '+'-operator for also string concatenation amongst summing and array merging. Especially because PHP is juggling with types a bit similar to JS, but not quite. The whole types don't matter thing would not be true if that were the case.
'1' + 2 = 3
