needle

parameter is omitted,
string
are assumed to be encoded in

not a string, it is converted to a string and applied as the ordinal
value of a character.
Returns the numeric position of the last occurrence of
needle
in haystack
.
The characters are counted
on the basis of the specified character set charset
.
If needle
is not found,
iconv_strrpos() will return FALSE.
