UTF-8安全Equantlant ord或charCodeAt（）在PHP [英] UTF-8 Safe Equivelant of ord or charCodeAt() in PHP

问题描述

我需要能够使用ord（）获得与javascript的charCodeAt（）函数相同的值。问题是，ord（）不支持UTF8。

I need to be able to use ord() to get the same value as javascript's charCodeAt() function. The problem is that ord() doesn't support UTF8.

如何在PHP中将Ą转换为260？我尝试了一些uniord功能，但他们都报告256而不是260.

How can I get Ą to translate to 260 in PHP? I've tried some uniord functions out there, but they all report 256 instead of 260.

非常感谢任何帮助！

推荐答案

ord（）每个字节（如大多数PHP标准字符串函数 - 如果不是全部）。您需要自己转换，例如在多字节字符串扩展的帮助下：

ord() works byte per byte (as most of PHPs standard string functions - if not all). You would need to convert it your own, for example with the help of the multibyte string extension:

$utf8Character = 'Ą';
list(, $ord) = unpack('N', mb_convert_encoding($utf8Character, 'UCS-4BE', 'UTF-8'));
echo $ord; # 260
