[SymfonyCon Berlin] A year of Symfony

Last year, Symfony 3 was out right before the SymfonyCon. A lot happened! 52 blog posts to help you keep up with all new things, 1200+ pull requests, 2 new versions out… Well I'm sure you missed something. Let's review what happened during last year: basically we'll see and/or discover nice new features that appeared since the last SymfonyCon.

35. • Implementation of the PSR-6 - Caching interface standard. • Cache arbitrary content in your application. • Symfony components use it to improve their performances. New component: Cache 3.1 class BlogController extends Controller { public function indexAction() { // create a new item and getting it from the cache $cachedCategories = $this->get('cache.app')->getItem('categories'); if (!$cachedCategories->isHit()) { $categories = ... // fetch categories from the database $cachedCategories->set($categories); $this->get('cache.app')->save($cachedCategories); } else { $categories = $cachedCategories->get(); } // ... } } Adapters for common backends Redis, APCu, Memcache…

78. Simpler command testing 3.2 use Symfony\Component\Console\Tester\CommandTester; $commandTester = new CommandTester($command); $helper = $command->getHelper('question'); $helper->setInputStream($this->getInputStream("123\nfoo\nbar\n")); protected function getInputStream($input) { $stream = fopen('php://memory', 'r+', false); fputs($stream, $input); rewind($stream); return $stream; } use Symfony\Component\Console\Tester\CommandTester; $commandTester = new CommandTester($command); $commandTester->setInputs(['123', 'foo', 'bar']);
