Let's say you were checking a db table for new rows. When a new row appeared, you'd break out of the loop and return the data to the page with the javascript that initiated the request (maybe you're PHP is returning JSON, XML, or an HTML fragment for the javascript to manipulate.) The javascript would update the page content and then initiate a new long-polling request and wait for new data. writing extension to php is also a very expensive way for me:( > I agree with you. That's in part why I suggested that the extension wouldn't be needed or worthwhile in this case and basic PHP would be a reasonable solution. -- Nephtali: A simple, flexible, fast, and security-focused PHP framework http://nephtaliproject.com
