ReactPHP如何访问此（绿色框）数据？

Question

Just some noob-ish question from me, How to get this (green boxed) data from This Image

(sorry i can't post image yet on stackoverflow because my reputation is still under 10. This is my first question on SO.)

I use laravel 5.7 and this packages:

• https://github.com/clue/reactphp-buzz
• https://github.com/dweidner/laravel-goutte

Code

App/MyScraper/Bukalapak.php

<?php
namespace App\MyScraper;

use Clue\React\Buzz\Browser;
use function React\Promise\all;
use React\Promise\PromiseInterface;

class Bukalapak
{
    private $browser;

    public function __construct(Browser $browser)
    {
        $this->browser = $browser;
    }

    public function scrape(string ...$urls): PromiseInterface
    {
        $promises = array_map(function ($url) {
            return $this->extractFromUrl($url);
        }, $urls);

        return all($promises);
    }

    private function extract(string $responseBody) : BukalapakObject
    {
        $crawler = new Crawler($responseBody);

        $name        = $crawler->filter('.c-product-detail__name')->text();
        $price       = $crawler->filter('.c-product-detail-price')->attr('data-reduced-price');
        $image       = $crawler->filter('.c-product-image-gallery__main img')->attr('src');
        $stock       = preg_replace('/[^0-9]+/', '', $crawler->filter('.qa-pd-stock')->text());
        $weight      = preg_replace('/[^0-9]+/', '', $crawler->filter('.qa-pd-weight-value')->text());
        $condition   = $crawler->filter('.qa-pd-condition-value > span.c-label')->text();
        $description = trim($crawler->filter('.qa-pd-description')->html(), "
");
        $assurance   = 'Tidak';
        $courier     = 'jner|j&tr';

        return new BukalapakObject($name, $price, $image, $stock, $weight, $condition, $assurance, $courier);
    }

    private function extractFromUrl(string $url) : PromiseInterface
    {
        return $this->browser->get($url)->then(function (ResponseInterface $response) {
            return $this->extract((string) $response->getBody());
        });
    }
}

<?php

use Illuminate\Http\Request;
use Clue\React\Buzz\Browser;
use App\MyScraper\Bukalapak;
use App\MyScraper\Helpers\BukalapakHelper;

class TestController extends Controller
{

    public function index()
    {
        $shop = 'https://www.bukalapak.com/u/attiqahijab';
        $urls = BukalapakHelper::fetchAllProductsLink($shop);

        $loop = \React\EventLoop\Factory::create();
        $browser = new Browser($loop);
        $scraper = new Bukalapak($browser);

        $data = $scraper->scrape(...$urls)->then(function($result) {
            return $result;
        });
        $loop->run();

        print_r($data);

        return view('backend.test');
    }

}

Expected Results:

Green boxed data only
