Whether or not you can preprocess a php page has to do with your web server (i.e., Apache, MS IIS, etc.). Default for PHP is that only files with the extention .php are processed (for PHP4 and 5). PHP3 used the extension .php3 and PHP2 used .phtml.
Try your page, with the HTML and the .php extension. It should work that way, or change the settings on your web server so that .html files are sent to be processed.
