Hello,
I have begun using the PHP Pages component, and all works well, until i attempt to pass my $_SESSION variables outside of joomla to a normal php page.
To discover/test this, i made a basic page through this component, and set the variable

session_start();
$_SESSION['mytestvar']='testable';

then, on another page, that was not run through joomla, i had the variable echoed back to me:

session_start();
echo $_SESSION['mytestvar'];

The echo on the separate page returned nothing, while an echo i did on another php page run through joomla returned/echoed 'testable'. Is this a bug, or part of the functionality of this component? Any more information you need, i will be more than happy to provide. thank you
