I know this isn't a php forum, but I can't see as I'll be doing any harm by asking a few resident php experts around these parts for some basic assistance!

Here's the problem. I'm learning php as fast as my little brain will allow and everything is running dandy on my local development machine.
Having just uploaded some of these test scripts onto the web I am finding that those scripts residing within .php files run fine. However, when embedding some php code into a html page via the <?php... ?> tags, I find that the page is not being passed to the php module on the server; the php tags are not being processed!
I've contacted the host company about this but my feeling is that they will not make the necessary adjustments to the .htaccess file (if one even exists on a Windows server?)
Now, I can get around this problem by having my webpage hand control completely to a php script which then generates the remainder of the html as appropriate. My question, therefore, is whether there is a html command which will cause a php script to be executed? I guess I'm basically asking if there's a way of having a html page redirect the user's browser to a php script?
Thanks in advance.
