I am not entirely clear what you are trying to do, but in general using a web browser, there is no way to have a persistent, bi-directional communication to an HTTP server. At least not one that you can control. There are ways to accomplish this kind of thing using JavaScript and iframes. So as as far as PHP and Postgres is concerned, the answer to your question is, "No, but it can be done." Keary Suska Esoteritech, Inc. "Leveraging Open Source for a better Internet"
Patricia, What you're looking for are "cron jobs". These are tasks that are scheduled to run periodically according to the criteria you specify. They are tied to the operating system (I'm assuming that you are running Linux). In order to run php functions with cron job you typically have the cron job execute a console function that executes a php script using the following format: /usr/bin/php -q [phpscriptname.php] Of course you need the standalone php executable in order for this to work. Post if you have more questions.
