Extra info for A Year With Symfony

Example text

Controller" event // use the controller resolver to get the controller arguments ... $response instanceof Response) { ... } } As you may remember from the Symfony documentation, a controller should return a Response object. If it doesn’t, some other part of the application should be able to convert the return value to a Response object in some way or another. 6 Enter the view layer When you choose to return a Response object directly from your controller, you can thereby effectively by-pass the templating engine: class SomeController { public function simpleAction() { return new Response( '

Pure old-fashioned HTML

' ); } } However, when you return anything else (though usually an array of template variables), this return value needs to be converted to a Response object before it can be used as a decent response to be sent back to the client.

Use a guard clause to return early (see the example above). II Patterns of dependency injection 5 What is a bundle? As we saw in the previous chapter: running a Symfony application means booting the kernel and handling a request or executing a command, where booting the kernel means: loading all bundles and registering their service container extensions (which can be found in the DependencyInjection folder of a bundle). xml file (but this can be anything) and the bundle’s configuration, defined in a separate class, usually in the same namespace, called Configuration.

Luckily - as we saw earlier - we can add tags to service definitions on the fly.
