Popis

int iconv_strrpos ( string $haystack, string $needle [, string $charset] )

Seznam parametrů

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.
