Her bağımsız olduğundan benim CMS, bazen gereksiz sorguları yapacak. Bu gibi önbellek sorguları için Tamam mı?:

        global $cache_query, $cache_result;
        if(!is_array($cache_query) || !is_array($cache_result) || !in_array($q,$cache_query))
        {//The query is new. 
            $r = query_($q);
            $cache_query[] = $q;
            $cache_result[] = $r;
        }
        else
        {//The query is cached.
            foreach($cache_query as $k=>$c) // Cycle through my cached queries to find the key. Is there an getElementKey function?
                if($c == $q) {
                    if(@mysql_fetch_array($cache_result[$k])) // is the resource is still valid?
                        mysql_data_seek($cache_result[$k], 0); // rewind the pointer
                    else
                        $cache_result[$k] = query_($q); // reset the resource
                    $r = $cache_result[$k];
                    break;
                }
        }
        return $r;

OR is a better practice to just make a new query each time? $q is my query, and the function query_() returns a resource and logs if something goes wrong.
