I mean, PHP license clause 3 & 4 seems to say this already:

  3. The name "PHP" must not be used to endorse or promote products
     derived from this software without prior written permission. For
     written permission, please contact [e-mail].

  4. Products derived from this software may not be called "PHP", nor
     may "PHP" appear in their name, without prior written permission
     from [e-mail].  You may indicate that your software works in
     conjunction with PHP by saying "Foo for PHP" instead of calling
     it "PHP Foo" or "phpfoo"

Edit: there may be more context than I thought

(I've edited my comment slightly, but not in a way that changes the context of your response.)

PHP License Clause 3 & 4 are about protecting PHP branding. Modified BSD Clause 3 is about using the software author's name or likeness as endorsement. For example, it limits putting antirez's face and name on our managed Redis product without obtaining his permission.

I don't think it does because trademark laws and individual rights already work like this by default.
