我的php代码无法选择mysql auto_increment值

function shopView(){
        global $core;
        $shop = mysql_query("SELECT * FROM services ORDER BY id DESC");
        $return = '<article>';
        if($shop){
        while ($row = mysql_fetch_array($shop)) {
            $return .= '<h4>'.$row['nazwa'].'</h4><a href="/go.html?url=index.php?view=buy&service='.$row['id'].'" class="button">Kup za '.$row['koszt'].' zl (+vat)</a>';
            }
        }
        else{
            $return .= 'Niestety coś poszło nie tak ;/';
        }
        $return .= '</article>';
        return $return;
    }
function shopView(){
        global $core;
