用另一个数组sortingmultidimensional array，并以相同的顺序完成丢失的键

我试图使用PHP / Laravel将导出表中的数据导出为ex​​cel，可以自定义导出表以显示特定列，导出列应与表列相同。 问题是 – 如果列不存在于一个特定的行中，列不显示为空，'xls'文件导出非常混乱…我的代码如下所示：

public function excelExport(Request $request, $client_id=null) { $client_id = is_null($client_id) ? \Auth::client()->id : $client_id; if(is_null($this->client_users)){ $this->client_users = $this->clientsController->listClientUsers($client_id); } $columns = $this->account_settings->getColumnsDef($client_id); $query = Lead::select(array_keys($columns))->where('client_id',strval($client_id))->where('deleted',0); $query = $this->setQueryDates($request,$query,$client_id); $query = $this->leadsFiltersController->setExportQuery($request,$query); $arr = $query->get()->toArray(); Excel::create('leads' , function($excel) use ($arr,$columns){ $excel->sheet('Leads' , function($sheet) use ($arr,$columns){ $rows = []; $count = 0; foreach($arr as $lead){ $row = $this->setExportRowData($lead,$count,$columns); $rows[] = $row; $count++; } $sheet->fromArray($rows); }); })->export('xls'); private function setExportRowData($lead,$count,$columns,$order = true) { $row = []; $order = null; foreach($lead as $k => $v) { if (is_array($v)) { switch (strtolower($k)) { case "ga_details": if (count($v) > 2) { foreach ($v as $key => $ga_detail) { if ($key != "realTime_data" && $key != "uacid") { $row[$key] = $ga_detail; } } } break; case "status": if (isset($v['name']) && count($v['name'])) { $row['status'] = $v['name']; } else { $row['status'] = "no status"; } break; case "owner": if (isset($v['owner_id']) && count($v)) { $row['owner'] = $this->getClientOwnerUserName($this->client_users, $v['owner_id']); } else { $row['owner'] = "no owner"; } break; case "prediction": if (isset($v['score']) && count($v)) { $row['prediction'] = $v['score']; } else { $row['prediction'] = "no prediction"; } break; case "the_lead": foreach ($v as $key => $lead_detail) { $row[$key] = $lead_detail; } break; case "quality": if (isset($v['name'])) { $row['quality'] = $v['name']; } else { $row['quality'] = "no quality"; } break; case "feeds": if (isset($v['feeds']) && count($v['feeds'])) { $row['feeds'] = array_pop($v['feeds'])['message']; } break; default : $row[$k] = $v; break; } } else { if ($k != "_id") { $row[$k] = $v; } } } return $order == true ? sortArrayByArrayValues($this->order,$row) : $row; } 

sortArrayByArrayValues函数看起来像这样：

 function sortArrayByArrayValues(Array $array, Array $orderArray) { $rtn = []; foreach($array as $arr){ if(isset($orderArray[$arr])){ $rtn[$arr] = $orderArray[$arr]; }else{ $rtn[$arr] = ''; } } return $rtn; } 

我真的不知道如何解决它，感谢任何帮助！ 🙂
