Yii Console

Yii Console package provides a console that could be added to an application. This console is based on Symfony Console. The following extra features are added:

• lazy command loader;
• SymfonyEventDispatcher class that allows to use any PSR-14 compatible event dispatcher with Symfony console;
• ErrorListener for logging console errors to any PSR-3 compatible logger;
• console command serve that runs PHP built-in web server;
• raises events ApplicationStartup and ApplicationShutdown in console application;
• class ExitCode that contains constants for defining console command exit codes;
• ConsoleBufferedOutput that wraps ConsoleOutput and buffers console output.

Requirements

• PHP 8.0 or higher.

Installation

The package could be installed with composer:

composer require yiisoft/yii-console

General usage

In case you use one of Yii 3 standard application templates, console could be accessed as ./yii <command>.

If not, then in the simplest use case in your console entry script do the following:

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

declare(strict_types=1);

use Yiisoft\Di\Container;
use Yiisoft\Di\ContainerConfig;
use Yiisoft\Yii\Console\Application;
use Yiisoft\Yii\Console\CommandLoader;

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

$app = new Application();

$app->setCommandLoader(new CommandLoader(
    // Any container implementing `Psr\Container\ContainerInterface` for example:
    new Container(ContainerConfig::create()),
    // An array with command names as keys and service IDs as values:
    ['my/custom' => MyCustomCommand::class],
));

$app->run();

Since \Yiisoft\Yii\Console\CommandLoader uses lazy loading of commands, it's necessary to specify the name and description in static properties when creating a command:

use Symfony\Component\Console\Command\Command;
use Yiisoft\Yii\Console\ExitCode;

final class MyCustomCommand extends Command
{
    protected static $defaultName = 'my:custom';
    protected static $defaultDescription = 'Description of my custom command.';
    
    protected function configure(): void
    {
        // ...
    }
    
    protected function execute(InputInterface $input, OutputInterface $output): int
    {
        // ...
        return ExitCode::OK;
    }
}

Run the console entry script with your command:

your-console-entry-script my/custom

When naming commands use : as a separator. For example: user:create, user:delete, etc.

Since the package is based on Symfony Console component, refer to its documentation for details on how to use the binary and create your own commands.

Aliases and hidden commands

To configure commands, set the names and aliases in \Yiisoft\Yii\Console\CommandLoader configuration. Names and aliases from the command class itself are always ignored.

The command can be marked as hidden by prefixing its name with |.

'yiisoft/yii-console' => [
    'commands' => [
        'hello' => Hello::class, // name: 'hello', aliases: [], hidden: false
        'start|run|s|r' => Run::class, // name: 'start', aliases: ['run', 's', 'r'], hidden: false
        '|hack|h' => Hack::class, // name: 'hack', aliases: ['h'], hidden: true
    ],
],

Runs PHP built-in web server

You can start local built-in web development server using the command:

./yii serve

Your application will be accessible in your web browser at http://localhost:8080 by default. To configure default settings, set the options in \Yiisoft\Yii\Console\CommandLoader configuration.

'yiisoft/yii-console' => [
    'serve' => [
        'appRootPath' => null,
        'options' => [
            'address' => '127.0.0.1',
            'port' => '8080',
            'docroot' => 'public',
            'router' => 'public/index.php',
        ],
    ],
],

Alternatively, you can pass the settings through the console options. To see the available options, run ./yii serve --help
