Short answer: It can't. Longer answer: There are probably 100 ways to get close to the result you are looking for. For instance, you could have each page on your site look for a flag in a DB, or a file in the filesystem, or some other clue. Then when the user loads a new page, the page discovers the event, and notifies him. PHP is server side. So everything it generates, it does so on page load. There are PHP/Javascript solutions (like AJAX) that may be able to get closer to what you want. We would need more detail for a more detailed answer.
