Create Phar with Symfony Console Component

We will extend our simple phar app from this article:

[Create PHAR file]

Now you can create composer.json with composer init, or add composer.json manually:

{
    "name": "scriptun/phar"
}

We need Symfony Console Component, so:

composer require symfony/console

Now we have vendor folder and composer.json updated. Edit index.php:

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

use Symfony\Component\Console\Application;

$application = new Application();
$application->run();

After running index.php you should see Symfony response:

Console Tool

Usage:
  command [options] [arguments]

...

So everything works fine, now we need our example console command to use.

Create: app/Command/TestCommand.php

<?php
namespace Scriptun\Command;

use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class TestCommand extends Command
{
    protected static $defaultName = 'app:test-command';

    protected function configure()
    {
        $this
            // the short description shown while running "php bin/console list"
            ->setDescription('Shows test message')
            // the full command description shown when running the command with
            // the "--help" option
            ->setHelp('This command allows you to show test message...');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $output->writeln('This is a TEST message');
    }
}

We need to load this class inside index.php, to do this, add autoload definition to your composer.json:

{
    "name": "scriptun/phar",
    "autoload": {
        "psr-4": {"Scriptun\\": "app/"}
    },
    "require": {
        "symfony/console": "^4.2"
    }
}

Register new command inside index.php:

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

use Symfony\Component\Console\Application;
use Scriptun\Command\TestCommand;

$application = new Application();
$application->add(new TestCommand());
$application->run();

Run it with:

php index.php app:test-command
> This is a TEST message

Works, now we can create phar by using our create.php file:

php create.php
php php scriptun.phar app:test-command
> This is a TEST message
