That is all I was hoping to ask. :-) Pear projects previously adopted
the PHP License almost by default. If it is still problematic, then it
should not be recommended.

You are correct that the big illegalities were dealt with. But there
some of the original problematic clauses still remain. I'll attempt to
briefly summarize here.

It is unclear whether this clause is even viable for PHP itself. This
looks like something that should be handled by a trademark, not by a
copyright.

That said, this clause is only relevant when applied to PHP itself. What
does it mean that "the name 'PHP' must not be used to endorse or promote
products derived from" CodeGen_PECL? Does that mean that any derivitves
of that package must modify the description which currently states
"CodeGen_PECL (formerly known as PECL_Gen) is a pure PHP replacement
for the ext_skel shell script". Does the phrase "pure PHP replacement"
use the name "PHP" to promote your product?

I simply can't think of a single case in which it would even be
desirable for a Pear package derivitive to be forbidden from using the
name "PHP" for its endorsement or promotion.

Regardless of what you think about the clause's applicibility to PHP
itself, it is clearly absolutely irrelevant to Pear packages.

The obvious intent of this clause is to prevent someone from making a
derivitive of PHP and the calling it "PHP Improved" or "SpeedyPHP". It
is understandable that PHP wouldn't want any of its derivitives to be
confused with the real PHP, or be incorrectly perceived as official
improvements/extensions to PHP.

But what does it mean when applied to Pear modules? If I make a
derivitive of your Image_Transform package, I can't call it
PHP_Image_Transform?

Or take phpDocumentor, released under the PHP License. If I were to
create a derivitive I would be forbidden from calling it phpDocumentor2
(even though the original was called phpDocumentor).

No Pear program (nor any other program besides PHP) is aversely affected
by a derivitive including PHP in its name. This clause simply is of no
value to anything except for PHP itself.


All right, that was probably more than you wanted to hear, but hopefully
it makes things more clear. :-)

Given that the only functionaly useful clauses in the PHP Licence when
used by Pear programs are those in the BSD License, it seems reasonable
to simply use that instead.
