설명

int mb_strpos ( string $haystack , string $needle [, int $offset = 0 [, string $encoding = mb_internal_encoding() ]] )

인수

haystack

needle

offset

The search offset. If it is not specified, 0 is used. A negative offset counts from the end of the string.

encoding

encoding 인수는 문자 인코딩입니다. 생략하면, 내부 문자 인코딩값을 사용합니다.

반환값

Returns the numeric position of the first occurrence of needle in the haystack string. If needle is not found, it returns FALSE.
