PHP：如何排序按字母顺序排列的数组值？ [英] PHP: How to sort values of an array in alphabetical order?

问题描述

我想在PHP中按字母顺序排列数组的值进行排序。如果所有的值开始使用相同的字符，然后将它们放在第二个字符等进行排序。忽略大小写敏感的。

I want to sort values of an array in alphabetical order in PHP. If all values started with same character then they should be sorted using second character and so on. Ignore case sensitive.

例如：

before:
values[0] = "programming";
values[1] = "Stackoverflow";
values[2] = "question";
values[3] = "answers";
values[4] = "AA Systems";

after:
values[0] = "AA Systems";
values[1] = "answers";
values[2] = "programming";
values[3] = "question";
values[4] = "Stackoverflow";

我已经发现了一些算法，但我想要的方式，速度快，有少数语句。忽略大小写是专门为我。谢谢你。

I have found some algorithms but I want a way that is fast and with small number of statements. Ignoring case sensitive is special for me. Thanks.
