class CreateTmpFile extends Action
{
    public $promises = ['file_path'];
    public function execute()
    {
        $this->context['file_path'] = tempnam(sys_get_temp_dir(), 'img_') . '.png';
    }
}

class Download extends Action
{
    public $expects  = ['url', 'file_path'];
    public function execute()
    {
        if (!@file_put_contents($this->context['file_path'], file_get_contents($this->context['url']))) {
            $this->skipRemaining();
        }
    }
}

class ZipFile extends Action
{
    public $expects  = ['file_path'];
    public $promises = ['zip_path'];
    public function execute()
    {
        $zip_path = str_replace('.png', '.zip', $this->context['file_path']);
        $zip = new ZipArchive();
        $zip->open($zip_path, ZipArchive::CREATE);
        $zip->addFile($this->context['file_path'], basename($this->context['file_path']));
        $zip->close();
        $this->context['zip_path'] = $zip_path;
    }
}

$organizer = new Organizer(['url' => 'https://upload.wikimedia.org/wikipedia/commons/thumb/2/27/PHP-logo.svg/100px-PHP-logo.svg.png']);
$result = $organizer->reduce([
  CreateTmpFile::class,
  Download::class,
  ZipFile::class
]);

print_r($result);

Progress Tracking

You can track the progress of action execution by passing a callback to reduce():

$organizer = new Organizer(['url' => 'https://example.com/image.png']);
$result = $organizer->reduce([
  CreateTmpFile::class,
  Download::class,
  ZipFile::class
], function(int $current, int $total, string $action, bool $skipped) {
    echo "[{$current}/{$total}] {$action}" . ($skipped ? ' (skipped)' : '') . "\n";
});

The callback receives:

• $current - Number of actions processed so far (1-indexed)
• $total - Total number of actions
• $action - The class name of the action just processed
• $skipped - Whether the action was skipped (due to skipRemaining())
