By "headers" Ed means "the first few bytes of the file". So the "file"
command does indeed identify PHP files perfectly:

$ file web/www/index.php
web/www/index.php: PHP script text
$ cp web/www/index.{php,rpm}
$ file web/www/index.rpm
web/www/index.rpm: PHP script text
$

So I think we can use this program to reliably detect file types,
whatever extension they may have, and filter them accordingly.
