What's best to use in managing time between php pages - Session or Database
<p>I have a simple question management portal to prepare students for an upcoming exam. In this software, a time is allocated for each student per test. </p>

<p>Here is the process I have at hand.</p>

<p>Student login, the page get like 80 unique ID which will be the question the student will answer, the page also get the time start and the first question loads on something like quest1.php then when the student click Next, the page saves the current time inside database. It pulls the saved time from the database and on and on like that.</p>

<p>Now when several people are using the portal, is it possible the mysql database got tired and may stop responding.</p>

<p>So the question is, is it good to save time inside Session instead of database.</p>
