How to achieve auto logoff in php?
<p>I need auto-logoff system in my application.</p>

<p>if user not using the application more than thirty minutes.they should log in again.</p>

<p>this is what i need.
lastAccessTime should be lesser than 30 minutes. if lastAccessTime exceeds than 30 minutes user should login again with their credentials.</p>

<p>(currently i auto log off using Lastaccesstime field in My user table (database) and compare lastaccesstime with current time for every page loads, I do not think this is right way.)</p>

<p>is their any way to achieve?
Thanks in advance.</p>
