laravel框架之数据库查出来的对象实现转化为数组

$produceStyle = exhibitionSql::allProduceStyle();//产品类型
    //var_dump($produceStyle);
    $j=0;
    $produceArray = Array();
    foreach($produceStyle as $value){
      //var_dump($value);
 
      $j++;
      $produceArray[$j]=$value->produceColorType;
 
    }

 public static function allProduceStyle(){//产品类型
    $data =DB::select("select distinct produceColorType from produce ");
 
    return $data;
  }

for($i=1; $i <= $j; $i++){
      // echo "sad";
      //var_dump($produceArray[$i]['produceColorType']);
      if($select == $produceArray[$i]){
        // echo "sda";
        $produceData =exhibitionSql::produceColor($select);//产品数据
        $CarouselData =exhibitionSql::secondCarouselData();//轮播图
        return view('B_page/produce',[
          'CarouselData'=>    $CarouselData,
          'produceStyle'=>    $produceStyle,
          'produceData'=>     $produceData
        ]);
      }

 public function object_array($array) {
    if(is_object($array)) {
      $array = (array)$array;
    } if(is_array($array)) {
      foreach($array as $key=>$value) {
        $array[$key] = object_array($value);
      }
    }
    return $array;
  }
