我有一个数组。我想改变他们的订单。这是一个我想只使用数组的数组。我只需要使用数组就可以做到这一点。

此阵列的长度可能会有所不同。现在，我想按顺序按字母顺序重新排列主题名称的顺序。
任何人都知道如何做到这一点？

你应该真正研究对象，你在数组中持有复杂的数据结构，这提供了难以维护和非直观的代码。
这是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的内置排序功能
http://php.net/manual/en/function.sort.php
或
http://www.php.net/manual/en/function.natsort.php
取决于你要完成的具体内容。
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;
}
