我想使用PHP函数按status_id对数组进行排序。我该怎么办？
以下是阵列的示例：
Array
(
[0] => stdClass Object
(
[status_id] => 4
[status_content] => {"text":"DET VIRKER JO IKKE!!!! ### >"}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 20
)
[1] => stdClass Object
(
[status_id] => 2
[status_content] => {"yt_vid":"Hb3MWuZT_W0","text":"Det her er jo bare awesome!!!"}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 20
)
[2] => stdClass Object
(
[status_id] => 8
[status_content] => {"text":"Hej"}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 1
)
[3] => stdClass Object
(
[status_id] => 7
[status_content] => {"text":"ff"}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 1
)
[4] => stdClass Object
(
[status_id] => 6
[status_content] => {"text":"h"}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 1
)
[5] => stdClass Object
(
[status_id] => 5
[status_content] => {"text":""}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 1
)
[6] => stdClass Object
(
[status_id] => 3
[status_content] => {"yt_vid":"PSLDZVh1Vtw","text":"This is really funny"}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 1
)
[7] => stdClass Object
(
[status_id] => 1
[status_content] => {"text":"This works, great! huh?"}
[status_likes] =>
[status_dislikes] =>
[status_owner] => 1
)
)
您需要使用array_multi-sort
http://php.net/manual/en/function.array-multisort.php
不过，首先循环获得玩具想要排序的所有项目的简单数组（状态id），然后将该变量与您想要在array_multi-sort 中排序的数组一起使用
一个选项是将usort与自定义排序函数一起使用。这里有一个小函数，它将根据一些属性名称为您构建一个闭包：
function buildSorter($key) {
return function ($a, $b) use ($key) { return strnatcmp($a->$key, $b->$key); };
}
使用这个，你可以：
usort($data, buildSorter('status_content'));
或
usort($data, buildSorter('status_owner'));
同样轻松。
感谢您的帮助！我知道我终于找到了答案，因为我环顾四周。
看一看。
usort($r, function($a, $b) {
return $a['status_id'] - $b['status_id'];
});
