session.auto_start 注意这个不要设为1,否则你在程序里就控制不了session的相关参数啦。 session.gc_maxlifetime = 1440; #默认after this number of seconds, stored , 24分钟 session.cache_expire = 180; #這是網頁過期時間設置; session.gc_probability = 1 session.gc_divisor = 1000 garbage collection 有个概率的,1/1000就是session 1000次才有一次被回收。 可以设置cookie的生命周期 session.cookie_lifetime = 0 ;默认0是关闭浏览器无效,单位是秒 max_execution_time = 600 max_input_time , 似乎是php从接收到处理数据的时间 While uploading large files, you should also increase the values for max_execution_time and max_input_time directives. Else your script will timeout or timeout before being able to parse the entire input/uploaded data.
