Maintaining state in php w/ session variables

[jip]

I am working in php and I am using the DW04 server behaviors for login, logout,
and restrict page access. I noticed that each of these behaviors uses a
session_start(). The login server behavior generates: //declare two session
variables and assign them $GLOBALS['MM_Username'] = $loginUsername;
$GLOBALS['MM_UserGroup'] = $loginStrGroup; //register the session
variables session_register('MM_Username');
session_register('MM_UserGroup'); How do I access these session variables on
subsequent pages? Does the presence of session_start() clear the current
session?

session_start() will either start a new session, or if one already exists,
resume it. So it doesn't clear a current session. Macromedia is a little
outdated now. The correct way to assign these variables to the session would
be.... $SESSION['MM_Username'] = $loginUsername; $SESSION['MM_UserGroup'] =
$loginStrGroup; then you can access the variables by....
$SESSION['MM_Username'] and $SESSION['MM_UserGroup'] hope this helps
