如何用PHP中的特殊字符替换它们？ [英] how to replace special characters with the ones they're based on in PHP?

问题描述

我如何替换：

• ã替换为a withe

这可能吗？我读过某个地方，我可以用基本字符的ascii值和口音的ascii值做一些数学，但我现在找不到任何引用。

in PHP? Is this possible? I've read somewhere I could do some math with the ascii value of the base character and the ascii value of the accent, but I can't find any references now.

推荐答案

此答案不正确。我不知道Unicode正规化当我写它。
查看francadaval的评论和链接

查看Normalizer类来执行此操作。文档很好，所以我只是链接它，而不是在这里重复：

Check out the Normalizer class to do this. The documentation is good, so I'll just link it instead of repeating things here:

http://www.php.net/manual/en/class.normalizer.php

具体来说，该类的规范化成员：

Specifically, the normalize member of that class:

http://www.php.net/manual/en/normalizer.normalize.php

请注意，Unicode规范化有几种形式，你似乎想要规范化形式KD（NFKD）兼容性分解，虽然你应该阅读文档以确保。

Note that Unicode normalization has several forms, and you seem to want Normalization Form KD (NFKD) Compatibility Decomposition, though you should read the documentation to make sure.

你不应该尝试滚动自己的函数为：有太多的东西可能会出错，使用提供的函数是一个更好的主意。

You shouldn't try to roll your own function for this: There's way too many things that can go wrong, and using the provided function is a much better idea.
