PHP Zend 2: Fatal Error - Class not found

Question

I'm trying to create own Model to do something (there will be calculations, moving in databases, and other non specifed work). But i got a problem, because I'm still getting and error that Class is not found.

Here is controller (module/Application/src/Application/Controller/IndexController.php):

namespace Application\Controller;

use Application\Model\Przesylki;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;

class IndexController extends AbstractActionController
{    

    public function indexAction()
    {
        $this->layout('layout/layout');
    }

    public function cennikAction() {
        $this->layout('layout/pusty');
        $logika_paczki = new Przesylki();
        echo $logika_paczki->return_word();
    }
}

Module.php (module/Application/src/Module.php):

namespace Application;

use Main\Model\Przesylki;

class Module
{
    const VERSION = '3.0.2dev';

    public function getAutoloaderConfig()
    {
        return array(
            'Zend\Loader\ClassMapAutoloader' => array(
                __DIR__ . '/autoload_classmap.php',
            ),
            'Zend\Loader\StandardAutoloader' => array(
                'namespaces' => array(
                    __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
                ),
            ),
        );
    }

    public function getConfig()
    {
        return include __DIR__ . '/../config/module.config.php';
    }
}

and a model, Przesylki.php (module/Application/src/Application/Model/Przesylki.php):

namespace Main\Model;

class Przesylki
{
    public function return_word() {
        return "word";
    }
}

if necessary, autoload_classmap.php (module/Application/src/autoload_classmap.php is just a

return array();

module.config.php:

namespace Application;

use Zend\Router\Http\Literal;
use Zend\Router\Http\Segment;
use Zend\ServiceManager\Factory\InvokableFactory;

];

Directories:

/config
    /autoload
/data
    /cache
/module
    /Application
        /config
            module.config.php
        /src
            /Application
                /Controller
                    IndexController.php
                    PanelController.php
                /Model
                    Przesylki.php
            autoload_classmap.php
            Module.php
        /test
        /view
/public

And when I run /cennik i got a Fatal, that class is not found:

[Tue Sep 06 08:58:20.446371 2016] [:error] [pid 4934] [client 195.8.99.234:1129] PHP Fatal error:  Class 'Main\\Model\\Przesylki' not found in /var/www/Paczucha_pl/module/Application/src/Main/IndexController.php on line 27

Actual files and namespaces:

Przesylki.php - Application\Model
IndexController - Application\Controller
PanelController - Application\Controller
module.config.php - Application
Module.php - Application

Answer 1

Okay finally I found a solution. Correct structure for given namespaces is :

/module
     /Application
         /config
             module.config.php
         /src
             /Controller
                 IndexController.php   // => Namespace : Application\Controller
                 PanelController.php   // => Namespace : Application\Controller
             /Model
                 Przesylki.php         // => Namespace : Application\Model
         /view
         /index
             /index
         /panel
             /panel

There shouldnt be double Application folder. I think it's Zend 3, maybe it changed.

Answer 2

You have problems with your namespaces. Your module's name is Application so your Model namespace should be Application\Main\Model.

Your module structure is not the recommended one for ZF2. It should be something as:

/module
     /Application
         /config
             module.config.ph
         /src
             /Application
                 /Controller
                     IndexController.php   // => Namespace : Application\Controller
                     PanelController.php   // => Namespace : Application\Controller
                 /Model
                     Przesylki.php         // => Namespace : Application\Model
         /view
             /index
                 /index
             /panel
                 /panel
