PHP SESSION variable assigning value to itself even before i declare it?
<p>I have a session variable <code>$_SESSION['divcontent']</code> in one of my pages.</p>

<p>I have a main page that calls an ajax function which runs the page with the above mentioned variable.</p>

<p>I have an <code>if (!isset)</code> clause which is only supposed to trigger if the above session variable is not yet set.</p>

<p>However it's not triggering at all. So i put an echo statement at the very beginning of this file to echo the variable, and it says its value is 0.</p>

<p>I have not referenced this variable in any other page. I changed the echo statement to echo a different variable not mentioned anywhere and it returned a variable not found error, as it should. I am viewing the page in live mode in dreamweaver. Each time i run it the session variables should reset to undeclared, shouldnt they?</p>

<p>Why is my variable self-instantiating at value = 0?</p>
