有关session_id
问个问题。

session_id

每关闭一次浏览器,再重新访问的时候,echo session_id()出来,会发现每次的id都不一样。

查了些资料,说跟session.cookie_lifetime = 0有关系,值为0的时候,浏览器关闭则保存于客户端的cookie会被删除掉,于是执行session_start()又要重新去生成一个id。

那我session.cookie_lifetime =9999将其值设为9999,不希望它关闭浏览器就过期,为什么重新打开浏览器仍然生成的session_id是不一样呢?

------解决方案--------------------
echo ini_get("session.cookie_lifetime");确保有效了?

另外,就算9999,GC还是会清理设定gc_maxlifetime的过期session文件的
