From manual page: http://www.php.net/function.strstr#refsect1-function.strstr-
examples

strrchr should be used for the first example instead. Because strrstrr only 
catches the first occurance of the letter from the beginning of the string. 
strrchr should be used to find the first occurance of the letter from the end of 
the string.
