iconv_strpos — Finds position of first occurrence of a needle within a haystack

Description

iconv_strpos ( string $haystack , string $needle [, int $offset = 0 [, string $charset = ini_get("iconv.internal_encoding") ]] ) : int

Finds position of first occurrence of a needle within a haystack.

In contrast to strpos(), the return value of iconv_strpos() is the number of characters that appear before the needle, rather than the offset in bytes to the position where the needle has been found. The characters are counted on the basis of the specified character set charset.
