require_once 'vendor/autoload.php'; use Symfony\Component\Filesystem\Filesystem; $filesystem = new Filesystem(); $data = 'Hello world!'; $filesystem->dumpFile('myfile.txt', $data);
require_once 'vendor/autoload.php'; use Symfony\Component\DependencyInjection\ContainerBuilder; use Symfony\Component\DependencyInjection\Reference; $container = new ContainerBuilder(); $container->register('database', 'PDO') ->addArgument('mysql:host=localhost;dbname=mydatabase') ->addArgument('myusername') ->addArgument('mypassword'); $container->register('datastore', 'My\DataStoreClass') ->addArgument(new Reference('database')); $data = array('key' => 'value'); $datastore = $container->get('datastore'); $datastore->save($data);In this example, we use the Symfony Dependency Injection Component to create a database connection and pass it to a data store object. We then save an array containing key/value data using the `save()` function of the data store object.
