$_SESSION, wise to use to hold data?
<p>I was wondering if using $_SESSION['data'] would be a smart way to hold information about a user who is logged in.</p>

<p>For example:</p>

<p>Say i have a game and i want to display their level/exp/username etc, well currently every page load i have to recall the database... so im wondering if i store it in a SESSION i can use a boolean to tell PHP if it needs to re-update its data... thus reducing the amount of MYSQL calls ?</p>

<p>Is this a smart idea of is there some flaw im unaware of ?</p>
