PHP Timer?

[AlexC]

i'm programming a members area, and have a problem

when the user logs in, it changes the value in column 'online' to yes, and when they logout, it changes to no

what i need is a timer, so that if they dont logout, it automatically logs them out after xx minutes

Use a cookie

[AlexC]

How?

thanx for quick response

I don't know much but you could use Javascript or PHP.

Ask in the Client Side Scriptin Forum, there you could find out how to do it using Javascript.

Thanx

is there any way i could do it in PHP?

its a cool script (or will be )

[petesmc]

You can do it in PHP, but again, i have no idea how. Try the php manual:

Why all the trouble when you can just use sessions and their builtin time out setting?

[wimpypenguin]

if you just need to respond to the fact that they have been at your page for a certain amount of time, set a cookie with a timer.

setCookie('user','valid', time()+600);

This will set a cookie with the variable $user = "valid" and will expire in 10 minutes (600 seconds). then you can just test whether that user is still valid when a page loads.

if($user == "valid"){
//they are a valid user here LT 10 mins
} else{ echo("get out"); }

I Know this porbably seems stupid, but how do i use the PHP Sessions timout feature?
