what is appvars.php?
<p>I was writing some php code with a couple friends of mine a while back.  I decided to look at some of the code we had written and noticed that almost all the php documents had the line: <code>require_once('appvars.php');</code> at the top.  I know that this isn't a built in php file, but one that they had created.  I figure it is probably something that they had copied from a tutorial or beginners book so I assume it is a common practice of sorts.  </p>

<p>in short: <strong>what are the contents of appvars.php</strong> and <strong>what is its purpose?</strong></p>

<p>note: The server has been offline for several months now so I don't have access to it and thus can't look at the source its self</p>

<p>many thanks stackoverflow</p>
