Well, that's not mentioned in the licence text you've quoted (which
clearly refers to the PHP *name*). If you have a look at the "PHP
Codebase" section at http://www.php.net/license/ it clearly states that
it's an open source licence with less restrictions than the GPL.
Following the OSD link:
3. Derived Works
The license must allow modifications and derived works, and must
allow them to be distributed under the same terms as the license
of the original software.
This is just the basic principle of open source software: it can be
free-as-in-beer or not, but it *has to* be free-as-in-speech. Derived
works are very common: just think of LibreOffice or all those MySQL
forks. But, in general, names and trademarks are different stuff. You
are free to make your own version of Red Hat but you need to give it a
different name (such as CentOS) because you don't own the "Red Hat" name
and its owner does not grant to permission to use it.
