Zend Framework 2 - How to use an external library - php

Question

I want to add my custom class "Authentication.php" to my project but I don't understand how I have to do it ?
I have read many howto about the external libs but nothing work.
ZendFramework/module/Firewall/Module.php
class Module
{
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
}
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
'MyNamespace' => __DIR__ . '/../../vendor/MyNamespace/lib/MyNamespace',
),
),
);
}
}
ZendFramework/vendor/MyNamespace/lib/MyNamespace
/Authentication.php
<?php
class Authentication {
public function test()
{
die('Works fine');
}
}
?>
How I can call my external lib in my controllers.
Thanks you very much !

Answer 1

I try like this:
1)
//module/Application/Module.php
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
'Mynamespace' => __DIR__ . '/../../vendor/Mynamespace',
),
),
);
}
2)
//vendor/Mynamespace/MyClass.php
namespace Mynamespace;
class MyClass
{
//...
}
3) I use it, for example in my controller:
use Zend\Mvc\Controller\AbstractActionController;
use Mynamespace\MyClass;
class AdminController extends AbstractActionController
{
public function indexAction()
{
$myclass = new MyClass();
}
}

For this kind of library, just type in your application.config.php
<?php
return array(
'modules' => array(
'ZendDeveloperTools',
'Application',
'YourLibrary' // <-- here
...

Answer 3

in composer.json file add the library as below
"require": {
"php": ">=5.3.3",
"zendframework/zendframework": ">2.2.0rc1",
"doctrine/doctrine-orm-module": "0.7.*",
"zendframework/zend-developer-tools": "dev-master",
"twig/twig": ">=1.12.3",
}
Then in your application.config.php
under the modules array
'modules' => array(
'Application',
'ZendDeveloperTools',
'ZfcTwig',
'DoctrineModule',
'DoctrineORMModule','yourdir',
),
So do something similar to it.
