To use the Symfony console to execute commands, you need to follow these steps:

  1. Create a new Symfony Console Application object:
1
2
3
use SymfonyComponentConsoleApplication;

$application = new Application();


  1. Define your commands by creating classes that extend SymfonyComponentConsoleCommandCommand. For example:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
use SymfonyComponentConsoleCommandCommand;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;

class MyCommand extends Command
{
    protected function configure()
    {
        $this->setName('my:command')
             ->setDescription('My custom command');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $output->writeln('Hello world!');
    }
}


  1. Add your commands to the application:
1
$application->add(new MyCommand());


  1. Run the console application:
1
$application->run();


You can execute the command my:command by running the following command on your terminal:

1
php console my:command


This will output Hello world! to the console. You can also get a list of all available commands by running php console list.
