Autoload
custom library in Zend Framework 2.0

I need to use autoloading for my custom classes in Zend Framework 2.0. My custom library located in
/vendor/Garvey/library/Garvey
.
I have a simple extended AbstractTable class in 
/vendor/Garvey/library/Garvey/Db/Table/AbstractTable.php
:
<?php

namespace Garvey\Db\Table;

use Zend\Db\Table\AbstractTable;

abstract class AbstractTable extends AbstractTable
{
public function getItemById($id)
{

}
}


In the index.php I have the following code:
require_once 'vendor/ZendFramework/library/Zend/Loader/AutoloaderFactory.php';
Zend\Loader\AutoloaderFactory::factory(array('Zend\Loader\StandardAutoloader' => array(
'prefixes' => array(
'Garvey' => 'vendor/Garvey/library/Garvey',
)
)));


But I have the following error. What I have missed?
Fatal error: Class 'Garvey\Db\Table\AbstractTable' not found


Thank you in advance.

Your original index.php would also worked if you changed the 'prefixes' key to 'namespaces' and specify path like below:
Zend\Loader\AutoloaderFactory::factory(array('Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
'Garvey' => dirname(__DIR__) . '/vendor/Garvey',
)
)));

Nice answer, just a little correction for this specific question: 
'Garvey'
=> dirname(__DIR__) . '/vendor/Garvey/library/Garvey'

plutov, you shouldn't need: require_once 'vendor/ZendFramework/library/Zend/Loader/AutoloaderFactory.php';– Matt

Or you can defime method in Module.php
public function getAutoloaderConfig()
{
$return = array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php'
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
'Garvey' => __DIR__ . '/../../vendor/Garvey/library/Garvey',
)
)
);
}


But I would not recommend it. Since ZF2 purpose all centered about speed in autoloading the best way is to use class_map style to load your classes. It will work much quicker at the end but require additional work. You can to register every class in you class_map
file.

You can create class_map.php in the root of your library and place there
<?php
return array(
'Garvey\Db\Table\AbstractTable' => __DIR__ . '/Garvey/Db/Table/AbstractTable.php',
);


And add there as many classes as you use. And in getAutoloaderConfig() you can add you classmap
public function getAutoloaderConfig()
{
$return = array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',
__DIR__ . '/../../vendor/Garvey/library/Garvey/class_map.php',
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
)
)
);
}

In my opinion this is the best answer. Using a class map is the a fast (if not the fastest) way to load classes and
therefor recommended by Zend. It's also clear and easy traceable. Good job clearing this method out, thanks! – Charlie

Matthew Weier O'Phinney explains in this video that
there are now 3 methods for autoloading :

ZF1-style include_path autoloader ( old zf1 method, not recommended )
Per-namespace/prefix autoloading ( new zf2 method, better )
Class-map
autoloading ( recommended and the fastest )

A class-map generator utility is mentioned
in the docs that will take care of writing the 
/vendor/vendor_name/library/autoload_classmap.php
for
you.

The solution you found is similar to the one Matthew mentions in the video for the Per-namespace/prefix autoloading. Following the code structure in ZendSkeletonApplication,
that code would go in the 
/init_autoloader.php
file,
rather than in the 
/public/index.php
file.

I have found the answer. Put this in your index.php:
require_once 'vendor/ZendFramework/library/Zend/Loader/StandardAutoloader.php';
$loader = new Zend\Loader\StandardAutoloader();
$loader->registerNamespace('Garvey', realpath('vendor/Garvey/library/Garvey'));
$loader->register();

It is the correct way. – Gabriel Jan

mmm a little frustrating. You may be new but I'm even newer! Where does the above go? I'm thinking public/index.php – Dominic

Yes, you correct. index.php – plutov.by Jan

Actually the correct way would be to have a module for this (only adding an autoloader to the application). – Fge Jan

You are not right. Module - is a part of application. Vendor - is a part for different applications. – plutov.byJan

Have a quick look at this post.

Now next step is add some code into our custom library.

First of all open a file 
./vendor/Garvey/autoload_classmap.php

return array(

'Garvey\Module' => __DIR__ . '/Module.php',

'Garvey\Db\Table' => __DIR__ . '/library/Garvey/Db/Table/AbstractTable.php',

)


Next is 
./vendor/Garvey/Module.php

namespace Garvey;

use Zend\ModuleManager\Feature\AutoloaderProviderInterface;

class Module implements AutoloaderProviderInterface
{
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',
),

'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/library/' . __NAMESPACE__,
),
),
);
}
}


Now inside your library create a file inside a folder:

./vendor/Kdecom/library/Kdecom/Db/Table/AbstractTable.php


One final thing that we need to do which is add this library into your 
application.config.php
file.

So your 
application.config.php
file
will looks something like this way...
return array(
'modules' => array(
'Application',
'Garvey'
),

'module_listener_options' => array(
'config_glob_paths'    => array(
'config/autoload/{,*.}{global,local}.php',
),

'module_paths' => array(
'./module',
'./vendor',
),
),
);
