* Finds the position of last occurrence (case insensitive) of a string in a string.
* @param string $haystack The string from which to get the position of the last occurrence.
* @param string $needle The string to be found.
* @param int $offset (optional) $offset may be specified to begin searching an arbitrary position. Negative values will stop searching at an arbitrary point prior to the end of the string.
* @param string $encoding (optional) The used internally by this function character encoding. If it is omitted, the platform character set will be used by default.
* @return mixed Returns the numeric position of the first occurrence (case insensitive) of $needle in the $haystack, or FALSE if $needle is not found.
* Note: The first character's position is 0, the second character position is 1, and so on.
* This function is aimed at replacing the functions strripos() and mb_strripos() for human-language strings.
