The FSF seems to disagree: quoting from
http://www.gnu.org/licenses/license-list.html#GPLIncompatibleLicenses

| PHP License, Version 3.01
|
| This license is used by most of PHP4. It is a non-copyleft free
| software license. It is incompatible with the GNU GPL because it
| includes strong restrictions on the use of “PHP” in the name of derived
| products.
|
| We recommend that you not use this license for anything except PHP
| add-ons.

As you may see, GPL *incompatibility* is explicitly stated.


P.S.: As most debian-legal regulars know, I don't agree that the PHP
license is a free software license, but that's another story...
