http - php.ini配置session.gc_maxlifetime无效，session依旧能访问
maxlifetime5秒，已经过期的了
probability和divisor均设置为1 1/1=100%过期后删除
但是这样session依旧有效？这是为什么呢?
与操作系统的机制有关吗，还是什么？
存放session/cookie的tmp文件夹中也依然存在该次调用的sessionid
PS:他大约是一个多小时更新一次，这和我配置的不符合啊

问题找到了，其实效果是有的（把值设成1比较明显），但是他的时间貌似有延迟，设置成1大概3，4秒才失效。
并且，无论设置成几，都必须刷新访问一次才会失效，第一次访问永远有效的
<code>ini_get()</code>
确认设置值是否生效
