Phalcon 3 和 PHP 7 打破现有网站

Question

在我将 PHP 升级到 Version 7 并将 Phalcon 升级到 Version 3 之后，我的问题就开始了。

问题

我得到空白页，没有错误消息 (Error is turned on)，控制台中没有“500 内部服务器”错误。该网站以前可以完美运行。

我有以下控制器IndexController.php

<?php

namespace RealEstate\Property\Controllers;

use \Phalcon\Mvc\Controller;
use \Phalcon\Mvc\View;
use  RealEstate\Common\Models as CommonModels;

class IndexController extends Controller
{
   public function initialize(){
          //Code here
   }

   public function indexAction(){
       $this->view->setRenderLevel(View::LEVEL_ACTION_VIEW);

       $this->view->setVar("total_properties", $this->utils->getTotalProperties());    
       $this->view->pick("index");
       echo "HELLO WORLD";
   } 
}

index 操作不会渲染任何内容，但是会打印 HELLO WORLD，因此该行上方的代码似乎没有错误。

我的引导程序index.php

也关注了This Link，但没有太多帮助。

更新 服务器的错误日志没有错误

谢谢

我想我解决了这个问题。问题出在Module.php，问题出在方法中

public function registerServices($di)
    {

        try{
            //Registering the view component
            $di->set('view', function() {
                $view = new View();
                $view->setViewsDir('../apps/modules/'.$this->module_name.'/views/');
                return $view;
            });

        }catch(\Phalcon\Exception $e){
            echo get_class($e), ": ", $e->getMessage(), "\n";
            echo " File=", $e->getFile(), "\n";
            echo " Line=", $e->getLine(), "\n";
            echo $e->getTraceAsString();
        }
    }

其中，$module_name 是在类中定义的属性。

在上面的代码中，$this->module_name 是未定义的。所以我把上面的方法改成了-

public function registerServices($di)
    {
        $module = $this->module_name;

        try{
            //Registering the view component
            $di->set('view', function() use($module) {
                $view = new View();
                $view->setViewsDir('../apps/modules/'.$module.'/views/');
                return $view;
            });

        }catch(\Phalcon\Exception $e){
            echo get_class($e), ": ", $e->getMessage(), "\n";
            echo " File=", $e->getFile(), "\n";
            echo " Line=", $e->getLine(), "\n";
            echo $e->getTraceAsString();
        }
    }

我想知道为什么它可以在以前版本的 Phalcon 中工作
