I've been using both mysql_fetch_array and mysql_fetch_assoc, and to me that using mysql_fetch_assoc is the best option for fetching an associative array because it only returns an associative array unlike mysql_fetch_array. But I've seen a lot of scripts written when mysql_fetch_array and just using the associative values. So does mysql_fetch_array have better performance or something, or am I just looking at outdated scripts?
One more question, why isn't mysql_fetch_assoc in the php manual on this site?
