$_SESSION['myvar']
becomes available as $myvar
after a session_start()
call.
$_POST['myvar']
becomes available as $myvar
after a form is posted.
I find the above behavior with the PHP installation/configuration on one server, but not on another server. How do I query whether the server is configured as such, and how do I configure the installation to change this behavior? I just can't find anything about this in php.net or elsewhere.
