我在记录用户时遇到问题。当日志、会话工作时，但当您单击另一个页面时，会话将消失且不工作。当我将session_start放入主页和login.php时，我发现错误，会话已在运行。一些想法？谢谢

只要在会话中输入值，就可以设置会话

$_SESSION["name"]=$value;

看看，还要清理用户输入，你的代码看起来很容易受到SQL注入的攻击，对我来说，“在整个网络上”——嗯？你的意思更像是“在整个网站上”，对吗？你也有一大堆被注释掉的代码，为什么？您是否启动了会话，并在所有文件中使用会话？我希望我不是白白打这些。像这样的提问者往往会忽略评论，只会让人们给出一个神奇的答案。是的，我的回答是正确的。^^是的，你是对的，再一次哈哈
