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?
Religion war?
ZF sucks!Symfony?Oh My!
Instead of think aboutZF2 || Symfony 2
think about
ZF2 && Symfony 2
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/
PSR-0
● Autoloading standard:
\<Vendor Name>\(<Namespace>\)*<Class Name>
Each namespace separator is converted to a DIRECTORY_SEPARATOR when loading from the file system
PSR-1
● Basic coding standard:
Files MUST use only <?php and <?= tagsNamespaces and classes MUST follow PSR-0Class constants MUST be declared in all upper case with underscore separatorsMethod names MUST be declared in camelCase...
PSR-2
● Coding style guide:
Code MUST follow PSR-1Code MUST use 4 spaces for indenting, not tabsThere MUST be one blank line after the namespace declaration, and there MUST be one blank line after the block of use declarationsOpening braces for classes MUST go on the next line, and closing braces MUST go on the next line after the body...
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...
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!
How to integrateHow to integrateZend Framework 2 in Symfony 2Zend Framework 2 in Symfony 2
composer create-project symfony/framework-standard-edition
project
Composer.json
"repositories": [ { "type": "composer", "url": "http://packages.zendframework.com/" } ],
Composer.json
"require": { "php": ">=5.3.3", "symfony/symfony": "2.2.*", (...) "zendframework/zend-crypt": "2.2.*" },
composer update
Now let's get to work
Register Crypt class as service
src/ZendCon/CryptBundle/Resources/config/services.xml
src/ZendCon/CryptBundle/Controller/CryptController.php
src/ZendCon/CryptBundle/Resources/views/Crypt/index.html.twig
http://zendcon.local/crypt
src/ZendCon/CryptBundle/Controller/CryptController.php
src/ZendCon/CryptBundle/Resources/views/Crypt/check.html.twig
http://zendcon.local/crypt
Other (better?) solutions
● Do validation in Entity● Use Symfony2 Validator
BlockCipher
src/ZendCon/CryptBundle/Controller/CryptController.php
src/ZendCon/CryptBundle/Resources/views/Crypt/blockcipher.html.twig
http://zendcon.local/crypt/block
Some stuff I won't show...

How to integrateHow to integrateSymfony2 in Zend Framework 2Symfony2 in Zend Framework 2
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)
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" } }}
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',
// ... ), ));
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)}
// ... ), ));
Use a service in a Controller
class AlbumController extends AbstractActionController{ public function indexAction() { $sm = $this->getServiceLocator(); $yamlParser = $sm->get('YamlParser'); $domCrawler = $sm->get('DomCrawler'); } // ...}
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
ConcludingConcluding
To integrate
● PSR / Framework Interoperability● Composer● Pick your components● Don't stop at Zend Framework/Symfony● Don't Reinvent The Wheel!
