You never store them in $_out nor are you returning $_out. Might this be the error? Probably you omitted some code, if so, then please provide the whole code (you could past it to 3v4l.org and provide the link) One other thing I spotted is the else if branch: else if(is_file) should be else if(is_file($_x)) Cheers, Robert
