for redirection purposes it is often necessary to generate a query string from POST/GET/_REQUEST variables, but not necessarily the same string that was passed to you (if one was passed at all) to count the keys in an array is easy (sizeof or count) - i needed one to count keys in the new query string for those who might find it useful, here is what i wrote for that purpose function count_query_args($qstring) { return (strlen($qstring)) ? count(explode("&",$qstring)) : 0; }
