sure...
i happen to be working with index.html and i want to '<?php include("somefile.html"); ?>'. the problem is "somefile.html" has head, body and meta tags that i want to automatically exclude and i'm wondering how to do that, else index.html will now have 2 sets of head, body and meta tags.
the normal way, afik, would be to manually remove the tags in "somefile.html" and give it a different extension, like ".inc" or whatever, but i want visitors to be able to view both files by themselves, as well as combined in "index.html". the site is sort of a blog and i create a new "somefile.html" every day. the latest would get included in "index.html" while older ones get archived.
