php会话变量不一致
我有一个php表单（称为Home.php），在提交（methodpost）时，我在一个单独的php脚本（称为Validate.php）中验证信息 验证后，会话变量将在Validate.php中初始化/设置。 设置好这些变量后，我将使用validate页面中的header（'Location:home.php'）重定向回home.php页面 所有这些工作都非常完美，我可以访问会话变量并将其显示在home.php页面上，但只要我点击refresh，变量值就消失了。即使我没有刷新home.php，如果我转到服务器上的另一个页面并尝试访问会话变量，它们也是空的/未设置 几点： 我在所有页面和最开始都有Session_Start（）。 会话保存路径配置值是/tmp，这似乎不是问题所在，因为我可以像上面提到的那样在第一次尝试时设置和检索会话值 我搜索了Stackoverflow和google，但什么也没找到。你是我最后的选择。希望有人能帮我 提前谢谢 Home.php:：php会话变量不一致,php,session,variables,persistent,Php,Session,Variables,Persistent,我有一个php表单（称为Home.php），在提交（methodpost）时，我在一个单独的php脚本（称为Validate.php）中验证信息 验证后，会话变量将在Validate.php中初始化/设置。 设置好这些变量后，我将使用validate页面中的header（'Location:home.php'）重定向回home.php页面 所有这些工作都非常完美，我可以访问会话变量并将其显示在home.php页面上，但只要我点击refresh，变量值就消失了。即使我没有刷新home.php，如果

Validate.php：
好的…这是我在我的代码中找到的，一旦我把它发布到这里。Home.php中的代码中有一个会话破坏，这就是造成这些恶作剧的原因
我删除了Session_Destroy（）和Onclick事件，所有这些都可以完美地工作，就像它设计的那样
谢谢迈克和丹的时间。你得把裙子抬起来，给我们看一些代码……你能添加一些代码吗？……哈……“抬裙子”……我刚提过……希望能有所帮助。谢谢
