Get the grunt-php to work

Question

I am trying to get the php server to work. I try to keep the code as simple as possible to make it work first. I have a folder in my D drive called firethis and it contains index.php. When i tell grunt-php to run, it gives me error. What am i doing wrong.

Thanks!

D:\>grunt php

module.exports = function(grunt){
grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
        php: {
            dist: {
                options: {
                    base: 'firethis'
                    }
                }
            },
grunt.loadNpmTasks('grunt-php');
grunt.registerTask('default', 'php');
