ThinkPHP5查询数据及处理结果的方法小结

$where=array(
  "version_id"=>$version_id
);
$data = model("PackageWhitelist")->where($where)->find();
$this->assign("package_id",$package_id);
$where=array(
  "package_id"=>$package_id
);
$data = model("Package")->where($where)->find();
if($data){
  $this->assign("target_version",$data['target_version']);
}

$device_number_list = model("PackageWhitelist")->where($where)->field("device_number")->find();

$this->assign("device_number",$device_number_list['device_number']);

$where=array(
     "version_id"=>$version_id
 );
$data = model("PackageWhitelist")->where($where)->field("device_number")->select();
$device_number_list='';
foreach($data as $val){
  $list = $val->toArray();
  if($device_number_list){
    $device_number_list=$device_number_list.';'.$list["device_number"];
  }else{
    $device_number_list=$list["device_number"];
  }
}

$where=array(
  "version_id"=>$version_id
);
$data = model("PackageWhitelist")->where($where)->select();
$device_number_list='';

  $list = $val->toArray();
  if($device_number_list){
    $device_number_list=$device_number_list.';'.$list["device_number"];
  }else{
    $device_number_list=$list["device_number"];
  }
}

public function index($version_id){
  $where=array(
    "version_id"=>$version_id
  );
  $version_name = model("Version")->where($where)->field("version_name")->find();
  $listrows=config("LISTROWS")"LISTROWS"):10;
  $package_lists=model("Package")->where($where)->paginate($listrows);
  $package_infos = $package_lists->toArray()["data"];
  foreach($package_infos as $key=>$value){
    $package_infos[$key] = array("source_version" => $version_name["version_name"]) + $package_infos[$key];
