说明

int mb_stripos ( string $haystack , string $needle [, int $offset [, string $encoding ]] )

mb_stripos() returns the numeric position of the first occurrence of needle in the haystack string. Unlike mb_strpos(), mb_stripos() is case-insensitive. If needle is not found, it returns FALSE.

needle: The string to find in haystack
offset: The position in haystack to start searching
encoding: Character encoding name to use. If it is omitted, internal character encoding is used.
