PHP数组Array按二维排序,先按第一个字段排序,再按第二个字段排序

sortMultiArray()最多支持3维数组排序,当然可以扩充的,自定义方法重载实现对多维数字的排序,这里的多维是说数据的多个字段。
使用方法:
1. sortMultiArray($data, [‘score' => SORT_DESC])
2. sortMultiArray($data, [‘score' => SORT_DESC, ‘count' => SORT_ASC])
3. sortMultiArray($data, [‘score' => SORT_DESC, ‘count' => SORT_ASC, ‘name' => SORT_ASC])
