你们中有人知道为什么我不能在 foreach 循环中使用（长）一段代码吗？
foreach 循环中的代码只执行一次。
topictweets.php 中的这段代码可以自己正常工作，但我想在每个论坛上重复它。没有包含的 foreach 循环可以正常工作。我还尝试将主题 tweets.php 中的代码清楚地放在 foreach 循环中，这当然也不起作用。
它包含的代码用于从数据库中获取论坛的主题并查找相关的推文，并将其保存在数据库中。
还有其他方法可以做到这一点吗？
foreach ($forumlist as $x => $fID) {
echo 'id:'.$fID.'<br>';
include 'topictweets.php';
