Microsoft started reaching out to PHP community members in 2006 because programmers were choosing to deploy PHP applications on Unix or Linux. Since 2009 Microsoft has offered the Web Platform Installer tool to install PHP on Windows. Microsoft still has a ways to go in convincing larger portions of the open source community that it means no harm. Microsoft’s own open source licenses, the Microsoft Public License and Microsoft Reciprocal License, are also incompatible with the free software license. The PHP scripting language has been around since 1995 and is distributed as free software under the PHP license.”]
