单分类
我是先读取各分类id，建立一个数组
然后再循环一次，读取各个分类下的文章，
这样一看效率就不高，能否一次或者两次读取生成数组呢。
另外最后生成的数组最好类似这样
Array
(
[0] => Array
(
[id] => 1
[name] => 资讯
[article] => think\Collection Object
(
[items:protected] => Array
(
[0] => Array
(
[id] => 2
[title] => 文章2
)
[1] => Array
(
[id] => 1
[title] => 文章1
)
)
)
)
[1] => Array
(
[id] => 2
[name] => 教程
[article] => think\Collection Object
(
[items:protected] => Array
(
[0] => Array
(
[id] => 3
[title] => 文章3
)
[1] => Array
(
[id] => 4
[title] => 文章4
)
)
)
)
[2] => Array
(
[id] => 3
[name] => 评测
[article] => think\Collection Object
(
[items:protected] => Array
(
[0] => Array
(
[id] => 5
[title] => 文章5
)
)
)
)
) 最佳答案
