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:
1 2 3 4 5 6 7 8 9 10 11 12 13 | #!/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.
