What exactly is it and how do you utilize it? Let me say this very clearly. Getting the data to the user *as soon as* it's entered into the DB is impossible unless you: 1) Have a PHP script which never ends and is constantly asking the DB for more data (this is very server resource intensive and it a *bad idea*) 2) Write a client program that does *not* rely on the web browser. You can use Java to make it load in the browser, but then it wouldn't be PHP. IMHO, your *only* bet to do this elegantly *with* PHP is to use some JS. Have a hidden iframe that the JS reloads every x seconds. The JS reads the data in the iframe and outputs new data to the user's screen. The user's page itself will never refresh. > > Thanks for all the help! > > Thanks, > Stephen Craton > http://www.melchior.us > > > > -----Original Message----- > From: Curt Zirzow [mailto:php-general@zirzow.dyndns.org] > Sent: Friday, June 25, 2004 12:53 AM > To: PHP List > Subject: Re: [PHP] Streaming > > * Thus wrote Stephen Craton: > > So my question is, does anyone know how the phpOpenChat system works? > > Can anyone provide some insight into the world of "streaming" and > > avoiding the refresh game? > > "streaming" > <?php > echo "data streamed to browser"; > ?> > > It is very unclear how you mean streaming, if you're talking about a HTTP > push method, then thats a whole nother ballpark. > > Curt > -- > First, let me assure you that this is not one of those shady pyramid schemes > you've been hearing about.
