PHP session garbage collection becoming an annoyance, i need some help to modify this behavior

I have been having this p开发者_StackOverflow中文版roblem for some time now, I dont exactly know that if this is the issue but I am pretty confident that it is, I have my remember me session set too expire after 1 week, but when I go to my site after a few hours of inactivity my remember me session is gone, i check my servers tmp dir and the session flat file is gone, what i think is happening is some PHP session garbage collector runs every now and then, but i dont want it to delete these sessions that are suppoes to be stored for a week, how do a modify this behavior?

You're confusing two things.

• A "remember me" mechanism doesn't rely on sessions. It relies on a cookie that stores credentials which are used to start a session. In this case, you have to setup the cookie so that is last for one week. See this answer.
• If you just want to extend the lifetime of sessions, you have to both extend the lifetime of the session cookie to one week and delay garbage collection. This is done changing session.gc_maxlifetime.
