The Console Component

The Console component eases the creation of beautiful and testable command line interfaces.

The Console component allows you to create command-line commands. Your console commands can be used for any recurring task, such as cronjobs, imports, or other batch jobs.

Installation

$ composer require symfony/console

Creating a Console Application

.. seealso::

    This article explains how to use the Console features as an independent
    component in any PHP application. Read the :doc:`/console` article to
    learn about how to use it in Symfony applications.

First, you need to create a PHP script to define the console application:

#!/usr/bin/env php
<?php
// application.php

require __DIR__.'/vendor/autoload.php';

use Symfony\Component\Console\Application;

$application = new Application();

// ... register commands

$application->run();

Then, you can register the commands using :method:`Symfony\\Component\\Console\\Application::add`:

// ...
$application->add(new GenerateAdminCommand());

You can also register inline commands and define their behavior thanks to the Command::setCode() method:

// ...
$application->register('generate-admin')
    ->addArgument('username', InputArgument::REQUIRED)
    ->setCode(function (InputInterface $input, OutputInterface $output): int {
        // ...

        return Command::SUCCESS;
    });

This is useful when creating a :doc:`single-command application </components/console/single_command_tool>`.

See the :doc:`/console` article for information about how to create commands.
