The Console Component

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¶

You can install the component in 2 different ways:

Install it via Composer (symfony/console on Packagist);
Use the official Git repository (https://github.com/symfony/console).

Then, require the vendor/autoload.php file to enable the autoloading mechanism provided by Composer. Otherwise, your application won't be able to find the classes of this Symfony component.

Creating a Console Application¶

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 add():

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

See the Console Commands article for information about how to create commands.
