通过XML的Symfony依赖注入

Question

I'm using the component (version 2.7) not the symfony framework.

I'm using PHP to inject and it is OK but I decided to use XML. I don't know how to load XML stored services into ContainerBuilder object,

I'm using the component this way:

$container = new ContainerBuilder();
$container->setDefinition('Crypt', new Definition('MiladRahimi\PHPCrypt\Crypt'));

The component is nicely documented . You'll find everything you need in the official docs.

Specifically, read on Setting up the Container with Configuration Files and Compiling the container . Make sure you dump the container for better performance .

Here's an example of loading an xml file, taken from the documentation:

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\Loader\XmlFileLoader;

$container = new ContainerBuilder();
$loader = new XmlFileLoader($container, new FileLocator(__DIR__));
$loader->load('services.xml');
