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


int mb_strrpos ( string haystack, string needle [, int offset [, 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.

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

Note: As of PHP 5.2.0 offset may be specified to begin searching an arbitrary number of characters into the string. Negative values will stop searching at an arbitrary point prior to the end of the string.

Note: As of PHP 5.2.0 encoding can be specified as the third parameter for backward compatibility, but not recommended. It is deprecated and will be removed from the future release of PHP.


5.2.0Added the optional parameter offset.
