Zend Framework 2 and Symfony2: The Perfect Team (PHPDay 2013)

The next generation of frameworks is upon us, and now that they're more decoupled and component-based than ever before and use the same standard for naming and autoloading, there is no reason to stick to a single framework for your projects. During this session, we will go through several ways of combining Zend Framework 2 and Symfony2, so that you walk away being able to focus even more on on writing the complex custom logic your project needs, and don't have to worry about the rest.

3. PHP frameworks
   ●
   Symfony and Zend Framework are the most
   used PHP frameworks worldwide
   ●
   Both offer a tons of features that can improve
   the development of web applications
   ●
   Modular architectures and high quality PHP
   code (SoC + SOLID principles)
   ●
   Why don't use it together to get the best
   features of both?

4. Religion war?
   ZF sucks!
   Symfony?
   Oh My!
   

   View Slide

5. Instead of think about
   ZF2 || Symfony 2
   think about
   ZF2 && Symfony 2

6. PSR-*
   ●
   Framework interoperability standards
   ●
   Meant to make it easier to work with multiple
   frameworks
   ●
   Naming standards and coding standards
   ●
   For instance: Only one autoloader!
   ●
   http://www.php-fig.org/

7. PSR-0
   ●
   Autoloading standard:
   \\(\)*
   Each namespace separator is converted to a
   DIRECTORY_SEPARATOR when loading from the file
   system
   

   View Slide

8. PSR-1
   ●
   Basic coding standard:
   Files MUST use only Namespaces and classes MUST follow PSR-0
   Class constants MUST be declared in all upper case
   with underscore separators
   Method names MUST be declared in camelCase
   ...
   

   View Slide

9. PSR-2
   ●
   Coding style guide:
   Code MUST follow PSR-1
   Code MUST use 4 spaces for indenting, not tabs
   There MUST be one blank line after the namespace
   declaration, and there MUST be one blank line after the
   block of use declarations
   Opening braces for classes MUST go on the next line,
   and closing braces MUST go on the next line after the
   body
   ...

10. PSR-3
    ●
    Logger interface:
    The LoggerInterface exposes eight methods to write
    logs to the eight RFC 5424 levels (debug, info, notice,
    warning, error, critical, alert, emergency)
    A ninth method, log, accepts a log level as first
    argument. Calling this method with one of the log level
    constants MUST have the same result as calling the
    level-specific method
    ...

12. Composer
    ●
    Composer (getcomposer.org) can help the
    management of projects that use ZF2 and
    Symfony2
    – Select your favorite ZF2 and Symfony2
    components using composer.json
    – $ php composer.phar install
    – Components installed in /vendor
    – Include the /vendor/autoload.php in your PHP
    code, that's it!

32. How to use Symfony2 in ZF2
    ●
    Use composer.json to include the Symfony2
    components
    ●
    Execute the update (or install) command of
    composer
    ●
    The Symfony2 composer will be installed in /vendor
    ●
    MVC approach:
    ●
    Register the Symfony2 components in the
    ServiceManager
    ●
    “Standard” approach:
    ●
    Use the Symfony2 components directly
    (instantiate the class and use it)

34. Symfony component as invokable
    // a module config "module/SomeModule/config/module.config.php"
    return array(
    'service_manager' => array(
    'invokables' => array(
    // Keys are the service names
    // Values are valid class names to instantiate
    'YamlParser' => 'Symfony\Component\Yaml\Parser',
    'DomCrawler' => 'Symfony\Component\DomCrawler\Crawler',
    // ...
    ),
    )
    );

35. Symfony component as factory
    // a module config "module/SomeModule/config/module.config.php"
    return array(
    'service_manager' => array(
    'factories' => array(
    // Keys are the service names.
    // Valid values include names of classes implementing
    // FactoryInterface, instances of classes implementing
    // FactoryInterface, or any PHP callbacks
    'YamlParser' => 'Symfony\Component\Yaml\Parser',
    'DomCrawler' => function ($html) {
    return new Symfony\Component\DomCrawler\Crawle($html)
    }
    // ...
    ),
    )
    );

36. Use a service in a Controller
    class AlbumController extends AbstractActionController
    {
    public function indexAction()
    {
    $sm = $this->getServiceLocator();
    $yamlParser = $sm->get('YamlParser');
    $domCrawler = $sm->get('DomCrawler');
    }
    // ...
    }
