session 的生命周期是多长
1 浏览器结束时其生命周期也同时结束，但是档案仍然存在于 /tmp/(sess_???)
2 下次重新开浏览器时会重新分配 sessionID,如果你使用 session_id() 把以前的 ID 带回来，则会去读取残存在 /tmp 处的 sess_???, 取回你之前所有已经设定的参数
3 可以在 php.ini 里修改 session 档案残存的时间
session.gc_maxlifetime = 1440 ; after this number of seconds, stored
; data will be seen as \'garbage\' and
; cleaned up by the gc process
默认是 1440 秒，24分钟
