Using PHP sessions exclusively for chatting
<p>I have written a small chat app that uses mysql + php to facilitate 1:1 chatting between users. I was wondering if it would be advisable to use only PHP sessions (using session injection) for chatting and only using mysql to find the session id of the users.</p>

<p>Will it be more efficient? Am i missing something out here?</p>

<p>Thank you for your time.</p>
