求判断PHP网站是否已经登录
我现在的需求是整合一个magento商城和一个论坛。主要是想做到两个网站共用一个会员登录。不用连续登两次。
我的做法是想先判断magento是否登录成功，如果是，那么就论坛也登录（这里的登录是指，从mangento那里获取用户名和密码，然后保存论坛登录成功后状态）。

------解决方案--------------------
可以两个网站连接统一数据库里面的同一个表，然后表里设一个值，类似于布尔值，可设0和1，两个网站打开时先检查这个值，如果为1，直接调用cookie登陆，如果为0，跳到登陆页面，输密码登陆，然后在登录后自动将此值设为1，在登出的时候以及cookie过期的时候将此值归0。。不知这个解答是否符合要求~

首先你要搞明白2个网站各自的登录原理是什么！看他们的登录判断时通过cookie呢还是session,还有就是2个网站各自的用户的怎么实现信息的共有化!要实现一站式登录,看以参考下dz的那套！
