How to Debug the Service Container & List Services

You can find out what services are registered with the container using the console. To show all services (public and private) and their PHP classes, run:

  1. $ php bin/console debug:container
  3. # add this option to display "hidden services" too (those whose ID starts with a dot)
  4. $ php bin/console debug:container --show-hidden

To see a list of all of the available types that can be used for autowiring, run:

  1. $ php bin/console debug:autowiring

Detailed Info about a Single Service

You can get more detailed information about a particular service by specifying its id:

  1. $ php bin/console debug:container 'App\Service\Mailer'
  3. # to show the service arguments:
  4. $ php bin/console debug:container 'App\Service\Mailer' --show-arguments
