从Fortnite Tracker API从JSON文件提取数据

我正在使用Fortnite Tracker API从我的网站中获取一些数据，一旦连接它就可以使用它，它将当前数据导出到JSON文件中。在我同时处理几个统计数据的同时，此方法效果很好，但由于某些原因，我无法使其与最近的比赛配合使用，有人可以看到我在这里出问题了吗？

的PHP

<?php

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, "https://api.fortnitetracker.com/v1/profile/psn/mygamertag");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
  curl_setopt($ch, CURLOPT_HEADER, FALSE);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array(
      'TRN-Api-Key: myapikey'
  ));
  $response = curl_exec($ch);
  curl_close($ch);
  $fp = fopen("myStats.json", "w");
  fwrite($fp, $response);
  fclose($fp);

  $data = json_decode(file_get_contents("myStats.json"));
  $solo = $data->stats->p2;//solos data
  $duos = $data->stats->p10;//duos data
  $squads = $data->stats->p9;//squads data

  $matches = $data->recentMatches;//match data
  $sesh1 = $matches[0]->id->valueInt;

  $solo_wins = $solo->top1->valueInt;
  $duos_wins = $duos->top1->valueInt;
  $squads_wins = $squads->top1->valueInt;
  $solo_matches = $solo->matches->valueInt;
  $duos_matches = $duos->matches->valueInt;
  $squads_matches = $squads->matches->valueInt;
  $solo_kd = $solo->kd->valueDec;
  $duos_kd = $duos->kd->valueDec;
  $squads_kd = $squads->kd->valueDec;
  $solo_games = $solo->matches->valueInt;
  $duos_games = $duos->matches->valueInt;
  $squads_games = $squads->matches->valueInt;
  $solo_kills = $solo->kills->valueInt;
  $duos_kills = $duos->kills->valueInt;
  $squads_kills = $squads->kills->valueInt;

  $total_matches = ($solo_matches+$duos_matches+$squads_matches);

  $total_wins = ($solo_wins+$duos_wins+$squads_wins);

  $total_kills = ($solo_kills+$duos_kills+$squads_kills);

  $total_kd = (round($total_kills/($total_matches-$total_wins),2));

  echo 'Total Matches: '.$total_matches.'<br>';
  echo 'Total Wins: '.$total_wins.'<br>';
  echo 'Total Kills: '.$total_kills.'<br>';
  echo 'Total KD: '.$total_kd.'<br>';
  echo $sesh1;
