Zend Skeleton Application A 404 error occurred Page not found - zend-framework

Question

I'm new to ZF. I'm using wamp 3. I followed the instructions from the Zend Framework Documentation (https://framework.zend.com/manual/2.4/en/user-guide/database-and-models.html), installed ZendSkeletonApplication and everything worked fine until step 3 (routing and controllers) when I got the error:
"A 404 error occurred
Page not found.
The requested URL could not be matched by routing.
No Exception available".
I don't know what the problem is, since I copied everything from the tutorial on the site (so that I don't make any typo) and it still won't work.
Any suggestions what the problem might be?
module.config.php looks like this:
return array(
'controllers' => array(
'invokables' => array(
'Album\Controller\Album' => 'Album\Controller\AlbumController',
),
),
'router' => array(
'routes' => array(
'album' => array(
'type' => 'segment',
'options' => array(
'route' => '/album[/:action][/:id]',
'constraints' => array(
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
),
'defaults' => array(
'controller' => 'Album\Controller\Album',
'action' => 'index',
),
),
),
),
),
'view_manager' => array(
'template_path_stack' => array(
'album' => __DIR__ . '/../view',
),
),
);
I did everything as they wrote, but when I go to "myvirtualhostname/album" it shows me the error above.

Answer 1

make sure you add this line (highlighted by comment) to the top of your public/index.php
<?php
use Zend\Mvc\Application;
use Zend\Stdlib\ArrayUtils; //<-- add this line
Note#1: you need to follow instructions of editing the index.php file for developing mode enabled, they just forgot to tell about using ArrayUtils in this tutorials.
Note#2 make sure to enable dev mod from the composer and dump autoload like this :
$ composer development-enable
and then:
[$ composer dump-autoload]

Answer 2

I believe you can specify the version you want to install with the initial composer command, something like this:
composer create-project -sdev zendframework/skeleton-application:^2.4 path/to/zf2-app
although you may be able to change the version on your existing skeleton app, it might be easier to run the above command in a different folder, and then copy over the files you've added or changed whilst following the tutorial.
And just to say again, unless you specifically need to learn ZF2.4, it would be better to stick with ZF3 (since that's the current version), and just follow the ZF3 tutorial instead. The differences between them are not that big.
