PHP问题。。。循环后输出停止

我得到了这个代码，在第一次输入后它就停止了，尽管应该还有更多。 如果我把两个foreach循环都取出来，效果会很好。所以问题应该存在，但我不是瞎就是笨：(

你必须在foreach循环中重命名

$stmt

变量。

我想我一小时前看到有人问过这个问题……你真的不应该在数据库字段中存储一个由

###

字符串分隔的ID列表。使用规范化的表设计（在你的例子中还有几个表将所有内容链接在一起），您可以在1或2个查询中获得所需的信息，而不是在循环中运行查询。嘿，我为什么不这样做呢？这是一个最多存储5个ID的字段…它使搜索特定信息变得几乎不可能，并且您运行的数据库查询比需要的多得多。@ficuscr-它的事件不太接近同样的问题。所以最好在投票前阅读。@jQuery那么请接受我的答案。必须等待5分钟才能这样做哈哈；-）
