Question

亲爱的，我正在为课程开发应用程序而且我被卡住了。问题是如何在保持全局变量的同时转到其他页面。

成功登录/注册（Ctr_Security-＆gt; process_login（）或Ctr_Security-＆gt; process_register（））后，用户应返回ctrl_main，同时保持全局$ messenger与之前相同，因为此变量存储各种错误，如“错误的密码“或像”注册成功“的信息。但是当我使用标题时（“位置：http://localhost:80/php_mine”）; $ messenger再次为空，之前存储的消息将丢失。如何重定向到丢失它们的其他页面？

的index.php

Answer 1

我用

解决了这个问题

include_once get_conf()->root_path.'/app/security/security_page.php';
exit();

exit（）阻止无限循环

PHP：继续/重定向到其他网址，同时保持SESSION / globals
