构造sql语句是 比起来
[U]复制代码[/U] 代码如下:
$sql = 'SELECT *
FROM sdb_comments
WHERE goods_id = '.intval($goods_id).'
AND for_comment_id IS NULL
AND object_type = ".$item."
AND disabled="false"
AND display = "true"';
我更喜欢这样做：
[U]复制代码[/U] 代码如下:
$sql = sprintf('SELECT *
FROM sdb_comments
WHERE goods_id = %.0f
AND for_comment_id IS NULL
AND object_type = "%s"
AND disabled="false"
AND display = "true"', (float)$goods_id, $item);
