RE: [PHP] Apache, html, php and global variables

Sessions use cookies, which use headers, which have to be sent before any output. <html> is output. So, put session_start() before that. <? Session_start(); ... ?> <html> <body> ... Where are you putting dbauser and dbapassword into the session? Your sessions still aren't going to work because the session.save_path isn't set correctly in your PHP.ini. Set it to a directory on your computer that the web server has access to write to. ---John Holmes... > -----Original Message----- > From: Peter Goggin [mailto:pgoggin@smartchat.net.au] > Sent: Saturday, June 01, 2002 9:54 AM > To: holmes072000@charter.net; php-general@lists.php.net > Subject: Re: [PHP] Apache, html, php and global variables > > I am not clear what you mean by this.
