php - 获取同一行中两列的值

Question

我需要同一行中两列(cnt、link)的值:

$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

如何获取这两个值？

Answer 1

您可以像这样使用 fetch_assoc() :

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