php把数据转成csv传到solr

$field = ['Peter','Griffin','Oslo','Norway','id'];
$data = [
                  ['Peter'=>43,'Griffin'=>4,'Oslo'=>32,'Norway'=>23,'id'=>1],//主键值必须有，比如这id等于1
                  ['Peter'=>43,'Griffin'=>5,'Oslo'=>32,'Norway'=>23,'id'=>12],
                  ['Peter'=>43,'Oslo'=>32,'Norway'=>23,'id'=>51],
                  ['Peter'=>43,'Griffin'=>6,'Oslo'=>32,'Norway'=>23,'id'=>31],
              ];
$core = 'test_update';
$csv_result = [$field];

      //处理数据，给不存在的值赋空值，不然CSV行列不对应
      foreach ($field as $files_value){
          foreach ($data as $data_key=>$data_value){
              $csv_result[$data_key+1][$files_value] = $data_value[$files_value];
          }
      }


      $file_name = time().$core.rand().'.csv';

      $file = fopen($file_name,"w") or exit("Unable to open file!");;

      foreach ($csv_result as $line)
      {
          $line = implode(',',$line);
          fputcsv($file,split(',',$line));
      }
      fclose($file);

      //获取当前的路径
      exec('pwd',$address);

      //上传到solr
      exec('curl http://127.0.0.1:8984/solr/'.$core.'/update?commit=true --data-binary @'.$address[0].'/'.$file_name.' -H \'Content-type:text/csv; charset=utf-8\'',$result);
      //删除生成的文件
      unlink($file_name);
      $result = implode('',$result);

      //上传成功
      if(strpos($result,'<int name="status">0</int>')){
          return ['status'=>true];
      }
      else{//上传失败
          //存日志到mongo
          $MongoModel = new MongoModel('集合', '', 'DB_MONGO');
          $MongoModel->add(['core'=>$core,'msg'=>$result,'field'=>$field,'data'=>$data]);
          return ['status'=>false,'msg'=>$result];
