ZF 2: tutorial application, 'Config being merged must be an array [...]' - php

Question

My Enviroment (Zend Server):
PHP Version 5.4.11
Zend Server Version: 6.0.1
Zend Framework: 1.12.3, 2.1.4
Zend Server Gateway: 0.9.0.201301302347
Build: 69400
So I tried to write my first application in ZF2 form official tutorial.
ZF version in skeleton application: 2.2
This is link to my project, if someone wants to look at it closer.
config/module.config.php
<?php
return array(
'controllers' => array(
'invokables' => array(
'Album\Controller\Album' => 'Album\Controller\AlbumController',
),
),
'view_manager' => array(
'template_path_stack' => array(
'album' => __DIR__ . '/../view',
),
),
);
module\Album\Module.php
<?php
namespace Album;
class Module
{
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 this is my error:
Zend\ModuleManager\Listener\Exception\InvalidArgumentException: Config being merged must be an array, implement the Traversable interface, or be an instance of Zend\Config\Config. integer given. in F:\Zend\Apache2\htdocs\learnzf2\vendor\zendframework\zendframework\library\Zend\ModuleManager\Listener\ConfigListener.php on line 317

What is problem with it? I tried to debug it but I don't know what is wrong with my code, except that is int value even I return array in config/module.config.php.
Ps. Eariler, I didn't use Xdebug (+PHPStorm), and when eg I put breakpoint somewhere into
config/module.config.php, it skips this breakpoint and go into (it don't even shows) and goes into ZF library files (where for example is another breakpoint). Is it normal or I'm doing sth wrong?

Answer 1

Your module/Album/config/module.config.php file is empty, while it should return a config array (like in the example code you've posted).

Answer 2

I had this same problem when I was about creating a new module after some time. I had other modules that were already working but this other one was giving the error you have now. In my search I realized that I wrote:
public function getConfig()
{
return __DIR__ . '/config/module.config.php';
}
instead of:
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
in my Module.php file. After correcting it my app works great! Please look through your code carefully especially in the Module.php and module.config.php files for omissions etc. Good luck!
