Nodejs php web server

server.js

//Lets require/import the HTTP module
var http = require('http');
var fs = require('fs');

var PORT=8080;
var spawn = require('child_process').spawn;


//We need a function which handles requests and send response
function handleRequest(request, response) {
    console.log('Requested file: ' + request.url);

    var file = request.url
    if (file === '/') {
      file = '/index.php';
    }
    if (file === '/favicon.ico') {
      response.end('');
    }

    if (file.substr(file.length - 4, 4) === '.php') {
      var php = spawn('php', ['.' + file]);

      php.stdout.on('data', function(data) {
        response.write(data);
      });

      php.on('close', function() {
        response.end();
      });
    } else {
      fs.readFile('.' + file, function(error, file) {
        response.end(file);
      });
    }
}

//Create a server
var server = http.createServer(handleRequest);

//Lets start our server
server.listen(PORT, function(){
    //Callback triggered when server is successfully listening. Hurray!
    console.log("Server listening on: http://localhost:%s", PORT);
});

An easy alternative could be to let PHP start a server on a port from the command line:
$ php -S localhost:8080
