我应如何使用PHP产量法

Question

我正在尝试编写一个API控制器，该控制器可以使用PHP提取用户的统计信息，但是我编写的工作非常缓慢。根据我的其他编程语言经验，我决定尝试使用屈服方法，但是出现错误，我该怎么办？提前致谢。

这是控制器代码

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\Http;

class splenperAPIController extends Controller
{
    public function splenperAPI()
    {

        $response = Http::withHeaders([
            'cookie' => 'sessionid=1796659686%3A4Ojj1py72bZKql%3A7;csrftoken=fPYrPRD1vHB7LdS0DjKzOK4kGo4uYK9f;',
            'x-ig-app-id' => '936619743392459',
        ])->get('https://www.instagram.com/elmaligroup/?__a=1');

        $response = $response->json();
        $userId = $response['graphql']['user']['id'];

        $first = 12;
        $variables = json_encode([
            'id' => $userId,
            "first" => $first,
        ]);

        $variables = urlencode($variables);
        $response = Http::withHeaders([
            'cookie' => 'sessionid=1796659686%3A4Ojj1py72bZKql%3A7; csrftoken=fPYrPRD1vHB7LdS0DjKzOK4kGo4uYK9f; ds_user_id=1796659686; ig_did=25114CCD-7A9D-4971-88F1-1E04796D9F14; ig_nrcb=1; mid=YiqZZQALAAEhkff6N5T2oovGOBkz; rur=01f73b7ee19feca3df296fc45ee75179c49dd54efb93233307b58f19bf707fea5d458fe7; shbid=01f7998eadf528233f0e7331b327e5a107134084c64e229af2cc6577b8a2ce862e3798da; shbts=01f7caf607a6877ca8407e9cb85cd175736a87f8f75e9076d5bddb32cbcbac6d5da45e89',
            'x-ig-app-id' => '936619743392459',
            'Content-Type' => 'application/json',
        ])->get('https://www.instagram.com/graphql/query/?query_hash=e769aa130647d2354c40ea6a439bfc08&variables=' . $variables);

        $mediaCount = $response->json()['data']['user']['edge_owner_to_timeline_media']['count'];
        $totalLikeCount = 0;
        $totalCommentCount = 0;
        for ($i = 0; $i < $mediaCount; $i++) {
           yield $totalCommentCount += $response->json()['data']['user']['edge_owner_to_timeline_media']['edges'][$i]['node']['edge_media_to_comment']['count'];
           yield $totalLikeCount += $response->json()['data']['user']['edge_owner_to_timeline_media']['edges'][$i]['node']['edge_media_preview_like']['count'];
           yield $userName = $response->json()['data']['user']['edge_owner_to_timeline_media']['edges'][$i]['node']['owner']['username'];
        }

        echo "userId:" . $userId . '<br>';
        echo "totalLikeCount:" . $totalLikeCount . '<br>';
        echo "totalCommentCount:" . $totalCommentCount . '<br>';
        echo "userName:" . $userName . '<br>';
        echo "mediaCount:" . $mediaCount;
    }
}

这是错误代码
