I am a bit surprised by the critical tone in the comments here. Phpdesktop [1] is, for example, a very nice application, and the ability of php to just make some simple scripts on the go and have something that works, is wonderful (compared to js where you often have to build etc, the threshold of getting started on a new computer is high). I have several times needed to make simple applications with a database, and php is perfect for that usecase. Making it simpler to share these applications to non-technical users for offline use is nice
