Alberto, I believe this comes under the heading of "no such thing as a free lunch", something needs to be reloaded to get the update from the server. Even an java applet with a direct database connection would need to go back to the database on the server to accomplish the update, but we were talking about PHP here, which has no presence in the browser. The typical agent present in the browser is JavaScript, and reguardless of technique, the question posed asked "can a portion of the webpage be updated without reloading the whole thing?" (at least that is how I understood the question). If you are proposing that the data on the webpage be updated without reloading anything at all, you have to ask "where does the new data come from?". I suppose if you are good at anticipating what you want to appear in the modified page you could transfer it with the original page and place it in the page with JavaScript based on some event, but I didn't think that is what you were looking for.
