function preforms much worse on CI

tnx for the answer, i looked up some info about caching and i can't understand how would this help speed up my function. just so we'll understand each other better, here's the function:

Code:

$path = __FILE__;            
        $path = str_replace("application\models\pic_load.php","JSandProducts\\".$type,$path);
        
        $count = 0;
        $handle = opendir ($path);
        $file = readdir ($handle);
        $file = readdir ($handle);
        while (false != ($file=readdir ($handle)))
        {
            $count += 1;
        }
        closedir ($handle);
        unset ($path,$file,$handle);
        return $count;

tnx again
