PHP is not a platform but a language. .NET is a framework for other languages that interfaces to Windows. If you use .NET, you'll need to learn how .NET works plus a language of some sort. If you use PHP, you only need to know PHP. PHP runs everywhere. .NET only runs on Windows (ignoring Mono which everyone does anyway).
Again with the anti Microsoft The majority who learn ".Net" will simply learn the likes of C# or VB.Net and so it isn't a case of having to learn two seperate things that drhowarddrfine seems to be hinting at. Likewise, for ASP.Net, it will need to be hosted on a windows box but anyone anywhere can access it Of cause one of the advantages of .Net is that as well as websites you could programme desktop applications (though here he is correct in saying that they would be predominately aimed at the windows market)
Did I say anything that wasn't true? You are implying that learning C# or VB means not having to learn .NET which is not true. You cannot get far with either of those languages without knowing .NET.
You cannot deny the power of .net. Combined with the Visual Studio's environment, it surpasses PHP. Like it or not.
.NET is merely a part of both languages, VB.NET or C#.NET. You wouldn't learn VB if you wanted to code VB.NET applications... you would learn VB.NET. A bit like VBScript and VB... similar but different, it is easy to adapt but they are still different...
Yes. You are right. The Windows framework .NET and the Windows editor VS are the best Windows combination on Windows.
I agree. The topic of the discussion is the creation of dynamic websites, so the platform that it is developed on is irrelevant. I would love to run linux, but two things: 1. It doesn't have a development environment that matches VS. 2. It doesn't have a decent CAD software (that compares to AutoCAD). Both of which I need, otherwise I would use linux...
They are different, but they are both useful for programming. If you use unix or linux system, I suggest php for programming, since .net just can work on windows system.
