- RouteCollection usage: Since 2.2, the
$prefixargument is not available. - You can add an extra RouteCollection into an existing one.
Filesystem
- Dump contents to a file: The correct method to dump contents to a file is
$fs->dumpFile('file.txt', 'Hello World');.
HTTP
- Idempotent HTTP verbs: The idempotent HTTP verbs are HEAD, CONNECT, GET, OPTIONS.
- Status code: The default status code of a Symfony\Component\HttpFoundation\RedirectResponse object is not 301.
Console
- Cursor usage: The cursor position can be changed in a command.
- Arguments variants: The built-in arguments variants are InputArgument::IS_ARRAY, InputArgument::OPTIONAL, InputArgument::REQUIRED.
Dependency Injection
- FindDefinition: The difference between findDefinition and getDefinition is that getDefinition resolves aliases.

$request->server. - Status code: The default status code of a Symfony\Component\HttpFoundation\RedirectResponse object is not 301.
Validator
- Constraints debug: The constraints of a class can be listed.
PHP Basics
- Namespaces: The correct way to import the hello namespace so that you can use the world() function is
use function myapp\utils\hello\world;. - Constant: As of PHP 5.6, the allowed data structures in a user-defined PHP constant are array, float, string, and boolean.
Event Dispatcher
- Connecting Listeners: To register the AcmeListener to the EventDispatcher, use
$dispatcher->addListener('acme.action', array($listener, 'onFooAction'));.
Form
- TextType children: The form types that do not inherit from the Symfony\Component\Form\Extension\Core\Type\TextType type are LocaleType, HiddenType, and RangeType.
- DataTransformer: A Symfony\Component\Form\Exception\TransformationFailedException thrown in a DataTransformer causes a validation error.
Twig
- Conditional include: The code
{% include foo|default('bar') ~ '_template.html.twig' %}is valid. - Node compilation: The Environment class calls the compiler.
Filesystem
- Mirror usage: When using mirror(...), files that are not present in the source directory can be deleted.
