The request for your index will be something along the lines of 'GET /'
meaning that there will be no notion of which file gets delivered. The
server will deliver whatever it is programmed to deliver. I think that
Apache gives precedence to PHP, then attempts index.html and then
index.htm. However, if the file itself changes (at the level of output, not
PHP source), its interpretation will probably vary.

Have you got anything in your site which points to /index.html or
/index.htm? If so, change it, but keep the old index files alive (I think
PHP supersedes HTML). Remember that caching might cause crawlers to have a
notion of the index file that you wish to get rid of. Maybe use a
re-direction like index.html>index.php and/or index.htm>index.php? I don't
think it will be frowned upon by SE's.

Yes, but I heard (and seen) bad things about its impact in practice.
