iconv_strrpos — Finds the last occurrence of a needle within a haystack

설명

int iconv_strrpos ( string $haystack , string $needle [, string $charset = ini_get("iconv.internal_encoding") ] )

Finds the last occurrence of a needle within a haystack.

In contrast to strrpos(), the return value of iconv_strrpos() 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.

인수

haystack: The entire string.
needle: The searched substring.
charset: If charset parameter is omitted, string are assumed to be encoded in iconv.internal_encoding.

If haystack or needle is not a string, it is converted to a string and applied as the ordinal value of a character.

반환값

Returns the numeric position of the last occurrence of needle in haystack.

If needle is not found, iconv_strrpos() will return FALSE.

Warning
