Sorry but you'll have to rewrite this code.
PHP is a dynamically-typed, interpreted language. C# (and any other language that runs on the CLR) is statically-typed and compiled.
If you are a web developer I recommend porting the site yourself. You should learn about PHP and how it differs from .NET.
They are two completely different paradigms in web development - knowing both will only make you stronger.
