二维数据字典

数据字典

这是buildadmin自带的数据字典，都是一维数组的形式，我想弄成二维的数据字怎么怎么弄呢？
就像下面这种数据结构，是个二维的：

"certificateType" => [
        0   => ['id' => 0, 'name' => '请选择','list' => [0 => '请选择级别']],
        1   => ['id' => 1,'name' => '学历证书','list' => [0 => '请选择级别',1 => '小学',2 => '初中',3 => '高中',4 => '中专',5 => '大专',6 => '本科']],
        2   => ['id' => 2,'name' => '护士证','list' => [0 => '请选择级别',1 => '护士执照',2 => '初级护士',3 => '初级护师',4 => '中级主管护师']],
        3   => ['id' => 3,'name' => '护理员证','list' => [0 => '请选择级别',1 => '初级',2 => '中级',3 => '高级',4 => '技师']],
        4   => ['id' => 4,'name' => '会计证','list' => [0 => '请选择级别',1 => '初级',2 => '中级',3 => '高级']],
