I use symfony's DI without symfony framework.
This is part of composer.json
"require" : {
"doctrine/orm" : "*",
"doctrine/migrations" : "^1.5",
"gedmo/doctrine-extensions" : "*",
"symfony/dependency-injection" : "3.4.17",
"symfony/config" : "3.4.17",
"symfony/yaml" : "3.4.17",
"twig/twig" : "^2.0",
"symfony/form": "^3.4",

},
This is how DI container is built
if (file_exists($containerFile)) {
require_once($containerFile);
$container = new \ProjectServiceContainer();
} else {
$container = new ContainerBuilder();
$container->setProxyInstantiator(new RuntimeInstantiator());
$loader = new YamlFileLoader($container, new FileLocator(__DIR__));
$loader->load(__DIR__.'/../config/services.yml');
$container->compile();
$dumper = new PhpDumper($container);
$containerDir = dirname($containerFile);
file_put_contents($containerFile, $dumper->dump());
}
In config/services.yml I've marked service as lazy
App\Services\MyService:
public: true
lazy: true
When I run some command for the first time it makes proxy object for MyService, when I run some command for the second time it takes MyService from cache/container.php and it is not lazy.
Part of generated cache/container.php
protected function getMyServiceService($lazyLoad = true)
The actual problem is that $lazyLoad variable is not used at all inside this function so constructor of MyService is called, but should be delayed, because some command does not use methods of this service at all.
