Is PHP the future of Microsoft?
It’s not that MS already made an official statement, but from what I read in the news, Microsoft not only started supporting PHP on Windows/IIS. Much more important is, that they are buying companies that use PHP (they could not close some deals yet, but at least they try to):
The next logical step is, that Microsoft runs PHP applications and employs a lot of PHP developers. I really don’t think, they will port all those apps to their own technologies like .net, C# or Visual Basic. So, be prepared. You will soon be able to start a career at Microsoft as PHP developer.
