설명
$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.
