Laravel where條件拼接，數組拼接where條件

問題描述：laravel where 條件拼接 Like出錯，搜索不到要搜索的內容。

問題代碼：

        // 作物
        $crop_class_id = $request->crop_class_id;
        if(!empty($crop_class_id)){
            $where['crop_class_id'] = intval($crop_class_id);
        }
        // 標題
        $title = $request->title;
        if(!empty($title)){
            // 這里的where獲取不到like條件
            $where['title'] = ['like', '%'.$title.'%'];
        }

正確代碼：

        // 作物
        $crop_class_id = $request->crop_class_id;
        if(!empty($crop_class_id)){
            $where['crop_class_id'] = intval($crop_class_id);
        }
        // 標題
        $title = $request->title;
        if(!empty($title)){
            // 如果拼接where條件存在比較符號，則不能指定key
            $where[] = ['title', 'like', '%'.$title.'%'];
        }

整體代碼：

// 獲取文章列表
    // @url api/user/article?article_class_id=1&status=1&crop_class_id=1
    public function index(Request $request)
    {
        $where = [];
        // 分類
        $article_class_id  = $request->article_class_id;
        if(!empty($article_class_id)){
            $where['article_class_id'] = intval($article_class_id);
        }
        // 狀態
        $status = $request->status;
        if(!empty($status)){
            $where['status'] = intval($status);
        }
        // 作物
        $crop_class_id = $request->crop_class_id;
        if(!empty($crop_class_id)){
            $where['crop_class_id'] = intval($crop_class_id);
        }
        // 標題
        $title = $request->title;
        if(!empty($title)){
            $where[] = ['title', 'like', '%'.$title.'%'];
        }
        $limit  = $request->input('limit');
        $deviceRegionList = ArticleModel::where($where)->orderBy('id','desc')->with('user', 'article_class', 'crop_class')->paginate($limit)->toArray();
        $returnData = [];
        $returnData['msg']              = "查詢成功";
        $returnData['count']            = $deviceRegionList['total'];
        $returnData['current_page']     = $deviceRegionList['current_page'];
        $returnData['data']             = $deviceRegionList['data'];
        return success($returnData);
    }
