session_start()

slevytam

Hello,

Could someone give me some info on sessoin_start(); I have this on each of my pages that requires session vars. The question is this:

First: can you set a length to the session?

Second: does session_start() automatically restart a session. Ie if default session length is 20 minutes and you keep calling session_start every 19 minutes will the session go on forever?
If not, how can this be done?

Thanks,

Sessions lengths vary depending on what the settings in php.ini are set to. The value session.cache_expire is the controlling command and it is in minutes. Use ini_alter to change the value of it because it is changable at the PHP_INI_ALL level.
Also, session_register() will resume a session that is already in effect. You can use session_name() to change between different sessions.

Ok, so session_resume() will Restart a session?

I dont see any function session_resume() on php.net. I have never heard of it either.

Thanks again,

So final confirmation.

If I use session_start(); followed by session_register(); the session will last for another 20 minutes.

Appreciate the help,

Yes, first call session_start to initialize and then use session_register() to register any variables into the session. All calls to session_start will resume a session so it will go for as long as php.ini says to.
