Description
$haystack
, string $needle

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.

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

needle in haystack.
If needle is not found,
iconv_strrpos() will return FALSE.
This function may
return Boolean FALSE, but may also return a non-Boolean value which
evaluates to FALSE. Please read the section on Booleans for more
information. Use the ===
operator for testing the return value of this
function.
