title: PHP- how to implement "don't save login" feature
body: <p>It's a common feature on an authentification page to set flag &quot;Remember me&quot; or &quot;Don't remember me&quot;.
  Ok, I have a session started for one year with user_id stored there. But if the user chooses to not remember him, and my usual session (+1 year) already started in the start-up section of my framework  - how can I change it to a temporary one, that will be destroyed on browser close?</p>
