将字符串转换为微不足道的代码时出现问题(在PHP中，使用phlyLabs的punycode字符串转换器) [英] Problem in converting string to puny code (in PHP, using phlyLabs's punycode string converter)

问题描述

我正在使用此处的代码: http://phlymail.com/en/downloads/idna/download/并构建了一个类似的功能(来自示例):

i'm using the code from here: http://phlymail.com/en/downloads/idna/download/ and built a function like this (from the example):

function convert_to_punycode($inputstring)
{
    $IDN = new idna_convert();
    // The input string, if input is not UTF-8 or UCS-4, it must be converted before
    $inputstringutf8 = utf8_encode($inputstring);
    // Encode it to its punycode presentation
    $outputstringpunycode = $IDN->encode($inputstringutf8);
    return $outputstringpunycode;
}

但是它不能正常工作.

For the input: Россию
It gives: РоÑÑиÑ
Whereas it should give: xn--h1alffa3f

我做错了什么?正在传递的$ inputstring是没有特殊声明/等的普通字符串.

What am I doing wrong? $inputstring which is being passed is a normal string with no special declarations/etc...

推荐答案

您的字符串已经是UTF-8吗?看起来像它. 还是在ISO-8859-5中? 在这两种情况下，您都不能使用PHP函数utf8_encode()，因为它期望您的输入字符串为ISO-88591-1(ISO Latin-1，西欧语言).查看随类源提供的文件transcode_wrapper.php.这可能会对您有所帮助.

Is your string already UTF-8? Looks like it. Or is it in ISO-8859-5? In both cases you cannot use the PHP function utf8_encode(), since it expects your input string to be ISO-88591-1 (ISO Latin-1, Western European languages). Look into the file transcode_wrapper.php, which is delivered with the class source. This might help you.
