that's correct.

another possibility is to use a template system. i like this because you can
have the html code and php code in separate files, which i find easier to
deal with. thus php files always begin with <?php and end with ?> and that's
the only place those tags are seen.

the separation is not 100% clean since there can be fragments of html inside
php strings where the php script generates html to put into the template.

you can find some template libraries in pear. and there are general purpose
php app frameworks that incorporate template (aka layout) schemes.
