$haystack,$needle,$offset = 0,$encoding = null
mb_strripos() performs multi-byte safe
strripos() operation based on
number of characters. needle position is
counted from the beginning of

пропущений або null, використається внутрішнє кодування.
Return the numeric position of
the last occurrence of needle in the
haystack string, or false
if needle is not found.
