(PHP 4 >= 4.0.6)

mb_strrpos -- Find position of last occurrence of a string in a string

Description

int mb_strrpos ( string haystack, string needle [, string encoding])

mb_strrpos() returns the numeric position of the last occurrence of needle in the haystack string. If needle is not found, it returns FALSE.

mb_strrpos() performs multi-byte safe strrpos() operation based on number of characters. needle position is counted from the beginning of haystack. First character's position is 0. Second character position is 1.

If encoding is omitted, internal encoding is assumed. mb_strrpos() accepts string for needle where strrpos() accepts only character.

encoding is character encoding. If it is not specified, internal character encoding is used.
