This is a matter for the webserver configuration. If you want the 
webserver to parse your .htm files with the php preprocessor, then you 
have to tell the webserver to do so. Normally the webserver by default 
will only send .php files to the php preprocessor.

Right. What happens here is that the web browser sees:

"<?php echo '<p>"

As an element tag, startiong at "<" and ending at ">" but it does not 
recognise it, so it ignores it. Then it sees:

"do you see this?'; ?>"

as document body text, and it displays it in the document body.

By adding the "<p>" you inserted a ">" character after the "<" of "<?php" 
and that ">" became the closing marker of the tag.

I've tried to explain this as clearly as I can, please re-read it until 
you are sure you understand it.
