note 18160 deleted from function.session-unregister by philip

If you use sessions to manage people coming on your site that way: -- People have a blank sessions when they connect. -- When they enter their password, session keep firstname & lastname: session_register('firstname'); $firstname='Julien'; session_register('lastname'); $lastname='Secret'; SO THE SESSION NOW CONTAIN: firstname|s:6:"Julien";lastname|s:6:"Secret"; -- There is a button to logout of the site, but the question is.. HOW TO BLANK HIS INFOS? - session_unset: keep variable name and that's really not a nice way (there is no reason to keep variables names). THE SESSION WILL CONTAIN: !lastname|!firstname| - session_destroy: will kill the session file and so remove all variables. But your user is still online and then have to get a blank session. Using session_destroy(); then session_start(); give an error. - session_unregister('firstname') works but you have to write all names of sessions variables. THE SESSION WILL CONTAIN: lastname|s:6:"Secret"; -- My solution is to use: global $HTTP_SESSION_VARS; foreach($HTTP_SESSION_VARS as $key => $value) { session_unregister($key); } /jc
