How many variables is to many when storing in _SESSION?
<p>I'm looking for an idea of best practices here. I have a web based application that has a number of hooks into other systems. Let's say 5, and each of these 5 systems has a number of flags to determine different settings the user has selected in said systems, lets say 5 settings per system (so 5*5). </p>

<p>I am storing the status of these settings in the user sesion variables and was wondering is that a sufficient way of doing it?</p>

<p>I'm learning php as I go along so not sure about any pitfalls that this could run me into! </p>
