Question: How to keep session alive for 1week without logout PHP, overwriting default server values?

I need to do this in the PHP code.

Answer: 
You can set the session lifetime in your script by using the session\_set\_cookie\_params -function call before the session is started. The first argument of the function call defines the session lifetime in seconds relative to the server time (so make sure the server clock is correct):

For example, to make a session last a week:

```
session_set_cookie_params(3600 * 24 * 7);
session_start();

```

This will override the setting in the php.ini -file.

Make sure to check up on the function documentation on the PHP -site: <http://www.php.net/manual/en/function.session-set-cookie-params.php>
Just wanted to add this even though it's an old thread for the sake of completeness for future googlers:

The `/etc/cron.d/php5` script will still clean your `/var/lib/php5/` directory containing your sessions based on the `php.ini` value `session.gc_maxlifetime`.
