使用npm：exec-php模块无法获取Phpvariables到我的节点Js

以下是Server.js文件，在这里我正在从表中获取工作良好的细节。 我需要从相同的Folder.Iam中使用npm exec-php模块来获取来自Php文件的值的k.php中的variables。 但variables显示未定义。

var app = require('http').createServer(handler), io = require('socket.io').listen(app), fs = require('fs'), express=require('express'), session=require('express-session'), mysql = require('mysql'), execPhp = require('exec-php'), connectionsArray = [], connection = mysql.createConnection({ host: 'localhost', user: 'root', password: '', database: 'test', port: 3306 }), POLLING_INTERVAL = 3000, pollingTimer; // If there is an error connecting to the database connection.connect(function(err) { // connected! (unless `err` is set) if (err) { console.log(err); } }); // creating the server ( localhost:8000 ) app.listen(8000); // on server started we can load our client.html page function handler(req, res) { fs.readFile(__dirname + '/client.php', function(err, data) { if (err) { console.log(err); res.writeHead(500); return res.end('Error loading client.php'); } res.writeHead(200); res.end(data); }); } execPhp('k.php', function(error, php, outprint){ // Here I expected The outprint Will be 'One' but it print undefined console.log(outprint); php.my_function(1, 2, function(err, result, output, printed){ //this my_function is also showing Error }); }); var pollingLoop = function() { // Doing the database query var query = connection.query('SELECT * FROM users where user_id=1'), users = []; // this array will contain the result of our db query // setting the query listeners query .on('error', function(err) { // Handle error, and 'end' event will be emitted after this as well console.log(err); updateSockets(err); }) .on('result', function(user) { // it fills our array looping on each user row inside the db users.push(user); }) .on('end', function() { // loop on itself only if there are sockets still connected if (connectionsArray.length) { pollingTimer = setTimeout(pollingLoop, POLLING_INTERVAL); updateSockets({ users: users }); } else { console.log('The server timer was stopped because there are no more socket connections on the app') } }); }; // creating a new websocket to keep the content updated without any AJAX request io.sockets.on('connection', function(socket) { console.log('Number of connections:' + connectionsArray.length); // starting the loop only if at least there is one user connected if (!connectionsArray.length) { pollingLoop(); } socket.on('disconnect', function() { var socketIndex = connectionsArray.indexOf(socket); console.log('socketID = %s got disconnected', socketIndex); if (~socketIndex) { connectionsArray.splice(socketIndex, 1); } }); console.log('A new socket is connected!'); connectionsArray.push(socket); }); var updateSockets = function(data) { // adding the time of the last update data.time = new Date(); console.log('Pushing new data to the clients connected ( connections amount = %s ) - %s', connectionsArray.length , data.time); // sending new data to all the sockets connected connectionsArray.forEach(function(tmpSocket) { tmpSocket.volatile.emit('notification', data); }); }; console.log('Please use your browser to navigate to http://localhost:8000'); 

主要的问题是在这些线

  execPhp('k.php', function(error, php, outprint){ // Here I expected The outprint Will be 'One' but it print undefined console.log(outprint); php.my_function(1, 2, function(err, result, output, printed){ //this my_function is also showing Error }); }); 

以下是在同一个文件夹k.php

  <?php echo "One"; function my_function($arg1, $arg2){ echo "Two"; return $arg1 + $arg2; } ?> 

这是错误
