有什么解决建议吗?

推荐答案

您可以使用foreach和ksort来实现

You can do it using a foreach and ksort

让$ your_array为您上面提到的数组

Let $your_array be the array you mentioned above

$res_array    = array();
foreach($your_array as $val){
   $res_array[$val->site_category][] = $val->site_name;
}
ksort($res_array);

print_r($res_array);

或在php中搜索多排序，将解决您的问题:)

OR search for multisort in php which will solve your problem :)
