DependencyInjection Component
|
|
=============================
|
|
|
|
DependencyInjection manages your services via a robust and flexible Dependency
|
|
Injection Container.
|
|
|
|
Here is a simple example that shows how to register services and parameters:
|
|
|
|
use Symfony\Component\DependencyInjection\ContainerBuilder;
|
|
use Symfony\Component\DependencyInjection\Reference;
|
|
|
|
$sc = new ContainerBuilder();
|
|
$sc
|
|
->register('foo', '%foo.class%')
|
|
->addArgument(new Reference('bar'))
|
|
;
|
|
$sc->setParameter('foo.class', 'Foo');
|
|
|
|
$sc->get('foo');
|
|
|
|
Method Calls (Setter Injection):
|
|
|
|
$sc = new ContainerBuilder();
|
|
|
|
$sc
|
|
->register('bar', '%bar.class%')
|
|
->addMethodCall('setFoo', array(new Reference('foo')))
|
|
;
|
|
$sc->setParameter('bar.class', 'Bar');
|
|
|
|
$sc->get('bar');
|
|
|
|
Factory Class:
|
|
|
|
If your service is retrieved by calling a static method:
|
|
|
|
$sc = new ContainerBuilder();
|
|
|
|
$sc
|
|
->register('bar', '%bar.class%')
|
|
->setFactoryClass('%bar.class%')
|
|
->setFactoryMethod('getInstance')
|
|
->addArgument('Aarrg!!!')
|
|
;
|
|
$sc->setParameter('bar.class', 'Bar');
|
|
|
|
$sc->get('bar');
|
|
|
|
File Include:
|
|
|
|
For some services, especially those that are difficult or impossible to
|
|
autoload, you may need the container to include a file before
|
|
instantiating your class.
|
|
|
|
$sc = new ContainerBuilder();
|
|
|
|
$sc
|
|
->register('bar', '%bar.class%')
|
|
->setFile('/path/to/file')
|
|
->addArgument('Aarrg!!!')
|
|
;
|
|
$sc->setParameter('bar.class', 'Bar');
|
|
|
|
$sc->get('bar');
|
|
|
|
Resources
|
|
---------
|
|
|
|
You can run the unit tests with the following command:
|
|
|
|
phpunit
|
|
|
|
If you also want to run the unit tests that depend on other Symfony
|
|
Components, install dev dependencies before running PHPUnit:
|
|
|
|
php composer.phar install --dev
|
