The file was completed, I omit the trailing PHP close tag, because PHP doesn't require a closing tag, and since in updates I do write to the local.config, it makes it easier. Most of the files have the closing tag also omitted to ensure there's no output before there's supposed to be.
Try downloading the full version of PHP, in the zip file, or the installer to do it. I think it's somewhere in the PHP directory, I'm not too familiar with IIS
