How to Debug the Service Container & List Services
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 2 3 4 | $ php bin/console debug:container
# add this option to display "hidden services" too (those whose ID starts with a dot)
$ php bin/console debug:container --show-hidden
|
New in version 4.1: Hidden services and the --show-hidden option were introduced in Symfony 4.1.
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 2 3 4 | $ php bin/console debug:container 'App\Service\Mailer'
# to show the service arguments:
$ php bin/console debug:container 'App\Service\Mailer' --show-arguments
