API call from 3rd party vendor returns a ZIP file, and I can't get it to unzip and parse in Phalcon

I'm connecting to an API to grab a ZIP, which contains JSON files. The vendor provides PHP code to connect, grab the ZIP, open it, and parse the JSON within. But I can't get it to work in Phalcon. Below is the code I'm using. It gets the ZIP, and Postman confirms things like my token, etc.I'm setting $token, etc, just left them out here. I suspect, but I'm not sure, that the issue might be the path to save the json, "files/myfolder"?

<?php

use Phalcon\Mvc\View;

class ReportController extends ControllerBase
{

    public function indexAction()
    {

      $projectName = "project+name";
      $token = "myAPItoken";

      $url = "https://api.awrcloud.com/v2/get.php?action=get_dates&token=" . $token . "&project=" . $projectName;

      $response = json_decode(file_get_contents($url), true);

      $dates = $response["details"]["dates"]; // date and search depth arrays

      foreach ($dates as $dateAndDepth)
      {
          $date = $dateAndDepth["date"];
          $depth = $dateAndDepth["depth"];

          $url = "https://api.awrcloud.com/get.php?action=list&project=" . $projectName . "&date=" . $date . "&token=" . $token . "&compression=zip";
          $rankingResultsResponse = file_get_contents($url);

          $responseRows = explode("\n", $rankingResultsResponse);

          if ($responseRows[0] != "OK")
          {
              echo "No results for date: " . $date;
              continue;
          }

          $dateFilesCount = $responseRows[1];
          if ($dateFilesCount == 0)
          {
              continue;
          }

          for ($i = 0; $i < $dateFilesCount; $i++)
          {
              $urlRequest = $responseRows[2 + $i];

                  fwrite($tempZip, $readChunk);
              }

              $res = $zip->open("tempfile.zip");

              if ($res === FALSE)
              {
                  echo "Could not extract JSON files from the zip archive";
                  continue;
              }

                  }

                  $rankings = json_decode(file_get_contents($pathToExtractedJson . $entry), true); // the json file contains nested json objects, make sure you use associative arrays

                  echo "";
                  echo "Search Engine: " . $rankings["searchengine"];
                  echo "Search Depth: " . $rankings["depth"];
                  echo "Location: " . $rankings["location"];
