strrchr — Find the last occurrence of a character in a string
This function returns the portion of haystack which starts at the last occurrence of needle and goes until the end of haystack .
The string to search in
If needle contains more than one character, only the first is used. This behavior is different from that of strstr().
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
This function returns the portion of string, or FALSE if needle is not found.

<?php
// get last directory in $PATH
$dir = substr(strrchr($PATH, ":"), 1);
// get everything after last newline
$text = "Line 1\nLine 2\nLine 3";
$last = substr(strrchr($text, 10), 1 );
?>
