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.

1. Zend Framework 2 and Symfony2: Zend Framework 2 and Symfony2: The Perfect Team The Perfect Team Stefan Koopmanschap, Enrico Zimuel 18th May – Verona (Italy)
2. About us • Stefan Koopmanschap • Enterpreneur: Ingewikkeld and Techademy • Member of Dutch Web Alliance • Symfony Community Manager • Co-Founder PHPBenelux, now PFZ.nl • stefan@ingewikkeld.net • Enrico Zimuel • Software Engineer at Zend Technologies • Zend Framework Core Team • Co-founder PUG Turin • enrico@zend.com
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!
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: \<Vendor Name>\(<Namespace>\)*<Class Name> Each namespace separator is converted to a DIRECTORY_SEPARATOR when loading from the file system
8. PSR-1 • Basic coding standard: Files MUST use only <?php and <?= tags 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 ...
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!
13. How to integrate How to integrate Zend Framework 2 in Symfony 2 Zend Framework 2 in Symfony 2
14. composer create-project symfony/framework-standard-edition project
15. Composer.json "repositories": [ { "type": "composer", "url": "http://packages.zendframework.com/" } ],
16. Composer.json "require": { "php": ">=5.3.3", "symfony/symfony": "2.2.*", (...) "zendframework/zend-crypt": "2.2.*" },
17. composer update
19. Now let's get to work
20. Register Crypt class as service
21. src/ZendCon/CryptBundle/Resources/config/services.x ml
22. src/ZendCon/CryptBundle/Controller/CryptController.p hp src/ZendCon/CryptBundle/Resources/views/Crypt/index.html.tw ig
23. http://zendcon.local/cry pt
24. src/ZendCon/CryptBundle/Controller/CryptController.p hp src/ZendCon/CryptBundle/Resources/views/Crypt/check.html.tw ig
25. http://zendcon.local/cry pt
26. Other (better?) solutions • Do validation in Entity • Use Symfony2 Validator
27. BlockCipher
28. src/ZendCon/CryptBundle/Controller/CryptController.p hp src/ZendCon/CryptBundle/Resources/views/Crypt/blockcipher.html.tw ig
29. http://zendcon.local/crypt/block
30. Some stuff I won't show... • Zend\Barcode • Zend\Captcha • Zend\Feed • Zend\I18n • ZendService_*
31. How to integrate How to integrate Symfony2 in Zend Framework 2 Symfony2 in Zend Framework 2
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)
33. composer.json { "require": { "php": ">=5.3.3", "zendframework/zendframework": "2.0.*", "symfony/yaml": "2.2.*", "symfony/dom-crawler": "2.2.*", }, "autoload": { "psr-0": { "Application": "module/Application/src" } } }
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'); } // ... }
37. Symfony 2 components • Some components useful for ZF2 users: – BrowserKit (simulates a web browser) – CssSelector – Filesystem – Finder (file search) – OptionsResolver – Process (executes commands in sub-processes) – Serializer (handle serializing data structures) – YAML parser
38. Concluding Concluding
39. To integrate • PSR / Framework Interoperability • Composer • Pick your components • Don't stop at Zend Framework/Symfony • Don't Reinvent The Wheel!
