Os Pilares do Zend Framework 2

Module Manager

O Que são Módulos?

Our ultimate goal is extensible programming. By this, we mean the construction of hierarchies of modules, each module adding new functionality to the system

Niklaus Wirth

Características do Module Manager

Gerencia os Módulos

Mescla as Configurações

Gerencia as Dependências

Extensibilidade de Módulos

Sobrescrita de Módulos

Autoload de Modules<?php return [ 'modules' => [ 'Sample' ], 'module_listener_options' => [ 'config_glob_paths' => [ 'config/autoload/{,*.}{global,local}.php' ], 'module_paths' => [ './module', './vendor' ] ] ];

config/application.config.php

Formatos: .phar, .phar.gz, .phar.bz2, .phar.tar, .phar.tar.gz, .phar.tar.bz2, .phar.zip, .tar, .tar.gz, .tar.bz2, e .zip.

<?php chdir(dirname(__DIR__)); /** @noinspection PhpIncludeInspection */ require 'vendor/autoload.php'; /** @noinspection PhpIncludeInspection */ Zend\Mvc\Application::init(require 'config/application.config.php')->run();

Módulo de Terceiro (ThirdUser)

<?php return [ ‘router’ => [ ‘routes’ => [ ‘user’ => [ ‘options’ => [ ‘route’ => ‘admin/user’, ], ], ], ], ];

Meu Módulo (MyUser)

<?php return [ ‘modules’ => [ ‘ThirdUser’, ‘MyUser’ ], ];

<?php return [ 'router' => [ 'routes' => [ 'user' => [ 'type' => 'Literal', 'options' => [ 'route' => 'admin/user', 'defaults' => [ '__NAMESPACE__' => 'Sample\Controller', 'controller' => 'User', 'action' => 'index', ], ], ], ], ], ];

Service Manager

O Que são Serviços?

A mechanism to enable access to one or more capabilities, where the access is provided using a prescribed interface and is exercised consistent with constraints and policies

as specified by the service description.Organization for the Advancement of Structured Information Standards (OASIS)
