What is the default value of a session variable?
<pre><code>&lt;?php
session_start();  
if(isset($_SESSION['views']))
    $_SESSION['views'] = $_SESSION['views']+ 1;
else
    $_SESSION['views'] = 1;

echo "views = ". $_SESSION['views']; 
?&gt;
</code></pre>

<p>Is $_SESSION['views'] initialized as FALSE?</p>

<p>EDIT: I meant the third line of code...</p>

<pre><code>if(isset($_SESSION['views']))
</code></pre>
