[S_panic]

I set a session in a php with this code
<?php
ob_start();
session_start();
$x="sa";
session_register($x);
?>

and I want extJs to get a $_session[x] variable.
how to do this?it can do this?

same way you would get any other piece of data from the server.
either echo it into the php script's output, or fetch it separately via ajax.

in javascript

var yourJSvar = '<?php echo $yourPHPvar?>';

and js variables into php are done via ajax etc
