An example of a class of a certain command:

<?php namespace AppBundle\Command; use Symfony\Component\Console\Command\Command; use Symfony\Component\Console\Input\InputInterface; use Symfony\Component\Console\Output\OutputInterface; class NewCommand extends Command { protected function configure() { $this ->setName('new-command') ->setDescription('Creates a new user.') ->setHelp('This command allows you to create a user...'); } protected function execute(InputInterface $input, OutputInterface $output) { $output->writeln('New command'); } }

How does symfony find this class and register it as a console command? After all, when autoloading, it is impossible to determine which classes are inherited from the base class (in this case, the Command class).

    Symphony registers teams in two ways:

    • It registers all commands from all registered bundles that are in the Command directory (in some version symfony removed this feature, I don’t remember which one, in the 4th it probably is not)
    • Manual registration of commands through the container, that is, create a service and add a tag called console.command

      In order for it to work, you need to register the command in bin / console; see the documentation https://symfony.com/doc/3.4/components/console.html

       #!/usr/bin/env php <?php // application.php require __DIR__.'/vendor/autoload.php'; use Symfony\Component\Console\Application; $application = new Application(); // ... register commands $application->add(new \AppBundle\Command\NewCommand()); $application->run();

      That's how it finds him

      • Yes, but if you use this component regardless of the symfony framework. When used with a framework, it is enough to add a command class to make the command available in the console. - sh1da9440
