I don't expect PHP to be active between <!--     -->.

<!-- ... --> is an HTML comment. /* ... */ and //... are PHP comments.

Taking a moment to explain the WHY of what's happening should help you understand it a bit more, Cor. All HTML markup - including comments - is parsed on the browser side, while PHP is done on the server side. The server doesn't parse HTML at all, and PHP doesn't have any knowledge of it's position within a script, or what else exists outside of the <? ?> tags. Thus, PHP is parsed, compiled, and executed prior to the web server serving the end-result as pure HTML, which is then parsed by the browser upon receipt. -- Daniel P.
