现在它在几天或几个月后显示错误消息“页面未正确重定向”。
index.php文件
require_once('WABRegistry/helpers/Session_Handler.php');
session_start();
它运行正常但是几天或几个月之后我们不得不要求支持人员重启apache并解决了我们的问题但是这次它没有用同样的错误可以请你帮忙
编辑：
它没有进入function write($sessID,$sessData) {
答案 0 :(得分：0)
当我将$sessData_new['z93my8/SztfFxc/d0w=='];更改为$_SESSION['z93my8/SztfFxc/d0w=='];它开始工作时，我使用{{1}}是我的错。
我也知道会话处理程序的写入功能没有写入可以在数据库中存储值的文件
