session variables's scope

[Black_Prince]

hi ..
.. i got an Index.php ..
.. it has a signIn.swf .. which calls upon signIn.php ..
.. i use sendAndLoad method from Flash to send and recieve the values, and so, the signIn.php page is never seen, though it worx fine.

.. question ....... if i set a session varable in signIn.php .. what would its scope be .. i mean .. would that also affect Index.php .. ? or would it be just lost, coz it never came to the browser window ?

You must always call session_start() if you want to use the $_SESSION or $HTTP_SESSION_VARS arrays. This function not only starts the session it continues a current session.
