PHP字符串中的Unicode字符 [英] Unicode character in PHP string

问题描述

这个问题看起来非常简单，但我一直找不到答案.

This question looks embarrassingly simple, but I haven't been able to find an answer.

与下面的C#代码行等效的PHP是什么?

What is the PHP equivalent to the following C# line of code?

string str = "\u1000";

此示例创建一个带有单个Unicode字符的字符串，其"Unicode数值"为十六进制的1000(十进制的4096).

This sample creates a string with a single Unicode character whose "Unicode numeric value" is 1000 in hexadecimal (4096 in decimal).

也就是说，在PHP中，如何创建一个具有"Unicode数值"已知的Unicode字符的字符串?

That is, in PHP, how can I create a string with a single Unicode character whose "Unicode numeric value" is known?

推荐答案

因为JSON直接支持\uxxxx语法，所以我想到的第一件事是:

Because JSON directly supports the \uxxxx syntax the first thing that comes into my mind is:

$unicodeChar = '\u1000';
echo json_decode('"'.$unicodeChar.'"');

另一种选择是使用mb_convert_encoding()

echo mb_convert_encoding('က', 'UTF-8', 'HTML-ENTITIES');

或利用UTF-16BE(大端)和Unicode代码点之间的直接映射:

or make use of the direct mapping between UTF-16BE (big endian) and the Unicode codepoint:

echo mb_convert_encoding("\x10\x00", 'UTF-8', 'UTF-16BE');
