කෝඩ් එකේ හැටියට user class එකේ constructor එකට parameter එකක් pass කරන්න ඕනේ. උබ user instance එක හදන කොට pass කරලා na.

//this config var need to pass into user ins
$config = new Config();
$userObj=new user($config); 


            $userResults=$userObj->getUsers(); 
            foreach ($userResults as $specificUser){ 
                echo $specificUser['name']; 
                echo '</br>'; 
            }
