It seems like pathinfo($file->getClien...ule\PATHINFO_EXTENSION) can also be of type array; however, parameter $string of strtolower() does only seem to accept string, maybe add an additional type check?

 If this is a false-positive, you can also ignore this issue in your code via the ignore-type   annotation
