int mb_strripos(string $haystack, string $needle[, int $offset = 0, string $encoding = mb_internal_encoding()])
mb_strripos() performs multi-byte safe strripos() 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. Unlike mb_strrpos(), mb_strripos() is case-insensitive.
Return the numeric position of the last occurrence of
needle in the
haystack string, or
needle is not found.
- string $haystack: The string from which to get the position of the last occurrence of
- string $needle: The string to find in
- int $offset [ = 0]: The position in
haystackto start searching
- string $encoding [ = mb_internal_encoding()]: Character encoding name to use. If it is omitted, internal character encoding is used.
