从同一行的两列中获取值

Question

I need values from two columns ( cnt , link ) in the same row:

$st = $db->query("select cnt, link from rolls where def = 1 limit 1");
$str = $st->fetch()['cnt'];
$link = $st->fetch()['link'];
echo $str; // this works
echo $link; // doesn't work - nothing is echoed

How to get both values?

Answer 1

You can use fetch_assoc() like that:

$st = $db->query("select cnt, link from rolls where def = 1 limit 1");
$str = $st->fetch_assoc();
echo $str['cnt'].' '.$str['link '];
