Derived from StreamWrapper, this class provides access to the local filesystem files.
The virtual working directory is handled by the PhpPath class in the Class Library. The absolute path resolution (using the working diretory and the include_path if necessary) and open-basedir check is performed by the PhpStream.ResolvePath method. This wrapper expects the path to be an absolute local filesystem path without the file:// scheme specifier.
