ThinkPHP - 博客获取列表信息

得到数据：

Array
(
    [0] => Array
        (
            [id] => 5
            [name] => PHP
            [pid] => 0
            [sort] => 1
            [blog] =>
        )

    [1] => Array
        (
            [id] => 2
            [name] => DIV+CSS
            [pid] => 0
            [sort] => 2
            [blog] => Array
                (
                    [0] => Array
                        (
                            [id] => 1
                            [title] => 这是一条测试文章
                            [time] => 1455717047
                        )

                )

        )

    [2] => Array
        (
            [id] => 3
            [name] => JavaScript
            [pid] => 0
            [sort] => 3
            [blog] => Array
                (
                    [0] => Array
                        (
                            [id] => 2
                            [title] => jquery博文
                            [time] => 1455763110
                        )

                    [1] => Array
                        (
                            [id] => 4
                            [title] => 博文博文
                            [time] => 1455869366
                        )

                )

        )

    [3] => Array
        (
            [id] => 4
            [name] => Apache
            [pid] => 0
            [sort] => 4
            [blog] =>
        )

    [4] => Array
        (
            [id] => 1
            [name] => HTML
            [pid] => 0
            [sort] => 5
            [blog] =>
        )

    [5] => Array
        (
            [id] => 6
            [name] => Linux
            [pid] => 0
            [sort] => 6
            [blog] =>
        )

    [6] => Array
        (
            [id] => 7
            [name] => 其他
            [pid] => 0
            [sort] => 7
            [blog] =>
        )

)

代码：

Public function index() {
    //获取所有父类分类
    $FaCate = M('Cate')->where(array('pid'=>0))->order('sort')->select();

    //获取所有分类
    $allCate = M('Cate')->order('sort')->select();

    // 引入分类类文件
    import('Class.Category', APP_PATH);

    $db = M('Blog');
    $field = array('id', 'title', 'time');//取出的字段
    foreach ($FaCate as $key => $value) {
        //根据父类id，获取子类id
        $cids = Category::getChildsId($allCate, $value['id']);
        //连同父类id一起放入数组，输出的结果是，父类id以及其下的所有子类id
        $cids[] = $value['id'];

        //根据查询出的id，查找博文表blog，获取博文数据,将博文数据放入Facate数组中的blog子数组中。
        $whe = array('cid'=>array('IN', $cids));//博文表中的查询条件，cid IN ('', '', '')
        //将查询除的数据放入blog数组中
        $FaCate[$key]['blog'] = $db->field($field)->where($whe)->select();//不能进行排序
    }

    print_r($FaCate);die;

    $this->cate = $FaCate;

    $this->display();
}

效果：
