can i run php in a node server code example

Example: run php on node js server

var http = require("http"),
fs = require("fs"),
path = require("path"),
url = require("url"),
runner = require("child_process");

function sendError(errCode, errString, response)
{
  response.writeHead(errCode, {"Content-Type": "text/plain;charset=utf-8"});
  response.write(errString + "\n");
  response.end();
  return false;
}

function sendData(err, stdout, stderr, response)
{
  if (err) return sendError(500, stderr, response);
  response.writeHead(200,{"Content-Type": "text/plain;charset=utf-8"});
  response.write(stdout);
  response.end();
}

function runScript(exists, file, param, response)
{
  if(!exists) return sendError(404, 'File not found', response);
  runner.exec("php " + file + " " + param,
   function(err, stdout, stderr) { sendData(err, stdout, stderr, response); });
}

function php(request, response)
{
  var urlpath = url.parse(request.url).pathname;
  var param = url.parse(request.url).query;
  var localpath = path.join(process.cwd(), urlpath);
  fs.exists(localpath, function(result) { runScript(result, localpath, param, response)});
}

var server = http.createServer(php);
server.listen(1000);
console.log("PHP ready to run script given on port 1000.");
