use Symfony\Component\DependencyInjection\ContainerBuilder; //Create a new instance of the container builder $containerBuilder = new ContainerBuilder(); //Define a service in the container with an alias $containerBuilder->register('example_service', ExampleService::class)->setAlias('alias_service', 'example_service'); //Check if alias_service exists in the container if ($containerBuilder->hasAlias('alias_service')) { echo "alias_service exists in the container"; }
use Symfony\Component\DependencyInjection\ContainerBuilder; //Create a new instance of the container builder $containerBuilder = new ContainerBuilder(); //Define a service in the container with an alias $containerBuilder->register('example_service', ExampleService::class)->setAlias('alias_service', 'example_service'); //Remove the alias for the service $containerBuilder->removeAlias('alias_service'); //Check if alias_service still exists in the container if (!$containerBuilder->hasAlias('alias_service')) { echo "alias_service has been removed from the container"; }This example demonstrates how to remove an alias for a service from the container. In this case, we registered a service called "example_service" and gave it an alias of "alias_service". We then remove the alias using the removeAlias method and use the hasAlias method to check if "alias_service" still exists in the container. The Symfony\Component\DependencyInjection package is the library that contains the ContainerBuilder class and other related classes and interfaces for dependency injection in Symfony.
