参考 Node.js 的 Commander, 写了一个 PHP 版本的 Commander（ Command Line Framework），不喜欢 symfony/console

<?php

use Lijinma\Commander;

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

$cmd = new Commander();

$cmd
    ->version('0.0.1')
    ->option('-p, --peppers', 'Add peppers')
    ->option('-P, --pineapple', 'Add pineapple')
    ->option('-b, --bbq', 'Add bbq sauce')
    ->option('-c, --cheese [type]', 'Add the specified type of cheese')
    ->parse($argv);


echo 'you ordered a pizza with:' . PHP_EOL;
if (isset($cmd->peppers)) {
    echo '  - peppers' . PHP_EOL;
}
if (isset($cmd->pineapple)) {
    echo '  - pineapple' . PHP_EOL;
}
if (isset($cmd->bbq)) {
    echo '  - bbq' . PHP_EOL;
}

if (isset($cmd->cheese)) {
    echo "  - $cmd->cheese cheese" . PHP_EOL;
}

<?php

use Lijinma\Commander;

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

$cmd = new Commander();

$cmd
    ->version('0.0.1')
    ->command('rmdir <dir> [otherDirs...]', 'Remove the directory')
    ->action(
        function ($dir, $otherDirs) {
            echo 'You will remove the following directory: ' . $dir . PHP_EOL;
            if ($otherDirs) {
                echo 'And other directories: ' . implode(', ', $otherDirs) . PHP_EOL;
            }
        }
    );

$cmd->command('rm <file>', 'Remove a file')
    ->action(
        function ($file) {
            echo 'You will remove the following file: ' . $file . PHP_EOL;
        }
    );

$cmd->parse($argv);
