This is a little PHP function to get the last n characters in a string. As you can see, it's pretty simple to do this with the native substr() function. I just forget how to do it a lot, so wrapping it in a method makes life a little easier for me.

  * Returns the last $n chararacters of a $str.
  public function LastNChars($str, $n)
    return substr($str, (-1*$n), -1);
