我是php新手。我正在开发一个网站，并且在不同页面上的会话有一些问题。当我登录网站时，我的标题变为
Main Reklam Logout Anna
当我点击我网站上的其他链接时会发生这种情况
Main Reklam Login Register
但是当我再次点击主要时，会话再次出现
Main Reklam Logout Anna
这是我的header.php

session_start();

在其他页面中（如OP提到的那样）请确保在使用$ _SESSION之前有session_start();功能。
例如
<?php
if (session_status() == PHP_SESSION_NONE) {
session_start();
/*session is started if you don't write this line can't use $_Session global variable*/
}
echo $_SESSION['user_id'];
