我使用PHP创建了一个小项目，大约有50个用户，每个用户都有自己的用户名和密码，而用户的主要功能是撰写帖子。
用户打开表单页面以撰写帖子，并在填写表单后单击添加按钮。
在这种情况下，表单操作将重定向到另一个页面并将其插入数据库，然后重定向到显示由登录用户撰写的帖子的主页。
问题在于，重定向首页时，已登录用户会看到另一位已登录用户的帖子。这种情况有时（并非总是）发生。
另一个有趣的事情是，如果在这种情况下用户单击F5按钮，则再次显示他自己的帖子。我已经尝试解决这个问题近两个月了。但是我找不到问题的原因。
有人可以帮助我吗？
注意：我使用SESSION进行身份验证！
init.php：
session_start();
session_regenerate_id();
require_once("session.php");
