RE: [PHP] Sessions and Query String Variable Handling

Not for server side. You can use a META REFRESH on the client side, but I personally find that ugly. This is why I always write my functions so that they don't output anything. They just assign the output to a variable and return it. That way, I can call the function anywhere, save the result, and just echo that variable where ever I need to. ---John Holmes... > -----Original Message----- > From: Dennis Moore [mailto:dmoore@ravens-nest.com] > Sent: Saturday, April 27, 2002 5:24 PM > To: holmes072000@charter.net; php-general@lists.php.net > Subject: Re: [PHP] Sessions and Query String Variable Handling > > Thanks, > > Is there any way of doing this without using the header() to redirect?
