Actually, you can just use substr($string, -1) to return to rightmost character in a string. Replace -1 with how many characters from the right you want to return, of course.

Thanks for the heads up Master Jake, I was unaware it supported negative values. I've updated the snippet to support your recommendations and in turn have a faster execution time.
