微信公众号自定义菜单wechat-php-sdk开发包$data传递什么值？

官方文档给出的代码

是要把$data拼接成上述样式吗？

试了不行，提示{"errcode":40016,"errmsg":"invalid button size"}错误

$data如果是纯数组形式呢？测试成功

$data = ['button'=>['type'=>'click','name'=>'今日歌曲','key'=>'V1001_TODAY_MUSIC']];
    // 实例微信菜单接口
		$menu = & load_wechat('menu');

		// 创建微信菜单
		$result = $menu->createMenu($data);

		// 处理创建结果
		if($result===FALSE){
				// 接口失败的处理
				echo $menu->errMsg;
		}else{
				// 接口成功的处理
				echo '成功';
		}

thinkphp创建微信自定义菜单完整代码：

/**
	 * 生成微信菜单
	 */
  public function createMenu(){
		$data = []; // 菜单内容
		// 获取一级分类
		$where[] = ['parentId','=',0];
		$where[] = ['isShow','=',1];
		$rs = $this->where($where)
			->order(['dataSort'=>'desc','menuId'])
			->limit(3)
			->select();
		if(false !== $rs){
			$button = [];

				$sub_button = [];		
				// 获取二级分类
				$where2 = [];

				if(false !== $rs2){
					// 如果二级分类不为空，则获取二级分类下的内容
