RE: [PHP] Unsetting Session Variables

PHP 4.2.2 Register Globals Off Using only $_SESSION No session_register() calls at all Interestingly enough, doing session_unregister('variablename') *in* *addition* does work (although I am sure it shouldn't) session_write_close() does not help Any suggestions? > -----Original Message----- > From: David Russell [mailto:DavidR@BarloworldOptimus.com] > Sent: 30 October 2002 14:32 > > I am having problems unsetting Session Variables - where I know it > should work. > > I have a form.

PHP version? register_globals on or off? Using only $_SESSION, or are there any session_register() calls? All of these can affect what you have to do to destroy session values, but... Have you tried doing session_unregister('variablename') *in* *addition*? Does session_write_close() help? Cheers!
