The PHP license is NOT Apache-style as it has no patent clause. It's a BSD/MIT style license with the added "name usage" caveat. To call such licenses "a better open source approach" is also incorrect. Unless you are defining "Better open source" to mean "easier for commercial entities to exploit without sharing back to the community, so they just get free labor", which is a rather poor way to define it (although the corporations that encourage MIT style over GPL do so for precisely that reason). They are "permissive licenses", in that they impose fewer restrictions on the developer at the cost of sacrificing protections for the end-user. Were the PHP engine itself still under the GPL, it would still not impact code you write in PHP. That can be in whatever license you like. (However, I would strongly encourage you to use the GPLv3 or AGPLv3 for your own code, as those are the only licenses that protect the end user from abuse. On the web, even the GPL only sort of does so, and AGPL is better for that.) --Larry Garfield
