Comments that are included within the PHP section of a web page are eliminated by the server when the PHP code is run, and so do not have an adverse effect on page load time. You should comment your PHP programs well.

Comments within the HTML section will be downloaded to the browser, slowing down page loading.

Bright programmers will switch into PHP mode to comment their HTML. It saves on download time, and it also means that anyone who views the source doesn't get too much help in "borrowing" the page.
