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

  1. Define the command: First, you need to create a command class that extends the SymfonyComponentConsoleCommandCommand class. This class should implement the configure() and execute() methods. The configure() method defines the name, description, and options/arguments of the command, while the execute() method defines the logic of the command.
  2. Register the command: After defining the command, you need to register it in the app/Console/Kernel.php file. You can do this by adding the command class to the $commands property of the Kernel class.
  3. Run the command: To execute the command, you need to run the Symfony console application using the php bin/console command, followed by the name of the command. You can also pass any options or arguments defined in the configure() method.


Here is an example of a command that outputs a message:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
20
21
22
23

// src/Command/HelloCommand.php

namespace AppCommand;

use SymfonyComponentConsoleCommandCommand;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;

class HelloCommand extends Command
{
    protected static $defaultName = 'app:hello';

    protected function configure()
    {
        $this
            ->setDescription('Outputs a hello message')
            ->setHelp('This command outputs a hello message to the console');
    }

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


Then, in the app/Console/Kernel.php file, you can register the command:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27

// app/Console/Kernel.php

namespace AppConsole;

use AppCommandHelloCommand;
use SymfonyComponentConsoleCommandCommand;
use SymfonyComponentConsoleCommandLoaderCommandLoaderInterface;
use SymfonyComponentConsoleCommandLoaderContainerCommandLoader;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;
use SymfonyComponentConsoleSingleCommandApplication;
use SymfonyComponentDependencyInjectionContainerInterface;
use SymfonyComponentHttpKernelBundleBundleInterface;

class Kernel
{
    // ...

    protected function getCommandLoader(ContainerInterface $container): CommandLoaderInterface
    {
        $commands = [
            new HelloCommand(),
            // ...
        ];

        return new ContainerCommandLoader($container, $commands);
    }
}


Now, you can execute the app:hello command by running the following command:

1

php bin/console app:hello
