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

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

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();

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)

O Que são Eventos?

An event is an action or occurrence recognised by software that may be handled by the software
