该数组的长度可能会有所不同。现在，我想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

Answer 1

您应该真正研究对象，您在数组中保存了复杂的数据结构，这提供了难以维护且不直观的代码。

这是一个关于php中对象的教程

http://php.net/manual/en/language.oop5.php

如果您坚持使用数组（并且没有充分的理由这样做），您可以使用 php 的内置排序功能

http://php.net/manual/en/function.sort.php

或者

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。

Answer 2

试试这个：

foreach ($arr as $key => $val) {
    ksort($val);
    $temp[$key] = $val;
}
