我有一个数组。我想更改他们的顺序。这是一个我只想使用数组的数组。我只需要使用数组来执行此操作。

此数组的长度可能会有所不同。现在，我想按 asc 顺序按字母顺序重新排列主题名称的顺序。
有人知道如何做到这一点吗？
谢谢
你应该真正研究对象，你在数组中保存复杂的数据结构，这提供了难以维护和不直观的代码。
这是关于 php 中对象的教程
http://php.net/manual/en/language.oop5.php
如果你坚持使用数组（并且没有充分的理由这样做），你可以使用 php 的内置排序函数
http://php.net/manual/en/function.sort.php
或
http://www.php.net/manual/en/function.natsort.php
取决于你到底要完成什么。
这两个页面都提供了使用示例。
试试这个：
foreach ($arr as $key => $val) {
ksort($val);
$temp[$key] = $val;
}
