$haystack
, string $needle
[, int $offset = 0
[, string $encoding = mb_internal_encoding()
]] )Finds position of the first occurrence of a string in a string.
Performs a multi-byte safe strpos() operation based on number of characters. The first character's position is 0, the second character position is 1, and so on.
haystackThe string being checked.
needle
The string to find in haystack. In contrast
with strpos(), numeric values are not applied
as the ordinal value of a character.
offsetThe search offset. If it is not specified, 0 is used. A negative offset counts from the end of the string.

인수는 문자 인코딩입니다. 생략하면, 내부 문자 인코딩값을 사용합니다.

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