PHP:使用iconv处理特殊字符

时间：2022-10-28 22:37:02

I still don't understand how iconv works.

我还是不明白iconv是怎么工作的。

For instance,

例如,

$string = "Löic & René";
$output = iconv("UTF-8", "ISO-8859-1//TRANSLIT", $string);

I get,

我得到了,

Notice: iconv() [function.iconv]: Detected an illegal character in input string in...

注意:iconv()函数。:在…的输入字符串中检测到一个非法字符。

$string = "Löic"; or $string = "René";

$ string =“卢”;或字符串美元=“刘若英”;

I get,

我得到了,

Notice: iconv() [function.iconv]: Detected an incomplete multibyte character in input string in.

注意:iconv()函数。iconv:在输入字符串中检测到一个不完整的多字节字符。

I get nothing with $string = "&";

$string = "&"我什么都得不到;

There are two sets of different outputs I need store them in the two different columns inside the table of my database,

我需要将两组不同的输出存储在数据库表中的两个不同列中，

  1. I need to convert Löic & René to Loic & Rene for clean url purposes.

    我需要将Loic和Rene转换为Loic和Rene，以实现清晰的url。

  2. I need to keep them as they are - Löic & René as Löic & René then only convert them with htmlentities($string, ENT_QUOTES); when displaying them on my html page.

    我需要保持它们的原样——Loic和Rene作为Loic和Rene，然后只使用htmlentities($string, ENT_QUOTES)转换它们;当在我的html页面上显示它们时。

I tried with some of the suggestions in php.net below, but still don't work,

我尝试了以下php。net中的一些建议，但仍然无效，

I had a situation where I needed some characters transliterated, but the others ignored (for weird diacritics like ayn or hamza). Adding //TRANSLIT//IGNORE seemed to do the trick for me. It transliterates everything that is able to be transliterated, but then throws out stuff that can't be.

我曾经遇到过这样的情况:我需要一些音译字符，但其他字符却被忽略了(比如ayn或hamza)。添加//TRANSLIT//IGNORE对我来说似乎很管用。它把所有能被音译的东西都音译了出来，然后又把那些不能被音译的东西扔掉。

So:

所以:

$string = "ʿABBĀSĀBĀD";

echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $string);
// output: [nothing, and you get a notice]

echo iconv('UTF-8', 'ISO-8859-1//IGNORE', $string);
// output: ABBSBD

echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT//IGNORE', $string);
// output: ABBASABAD
// Yay! That's what I wanted!

and another,

When doing transliteration, you have to make sure that your LC_COLLATE is properly set, otherwise the default POSIX will be used.

To transform "rené" into "rene" we could use the following code snippet:
setlocale(LC_CTYPE, 'nl_BE.utf8');

$string = 'rené';
$string = iconv('UTF-8', 'ASCII//TRANSLIT', $string);

echo $string; // outputs rene

How can I actually work them out?

我怎么才能算出来呢?

Thanks.

谢谢。

This is the source file I test the code,

这是我测试代码的源文件，

<?php
$string = "Löic & René";
$output = iconv("UTF-8", "ISO-8859-1//TRANSLIT", $string); 
?>

And did you save your source file in UTF-8 encoding? If not (and I guess you didn't since that will produce the "incomplete multibyte character" error), then try that first.

您是否将源文件保存为UTF-8编码?如果没有(我猜您没有，因为这会产生“不完整的多字节字符”错误)，那么请先尝试一下。

$clean = iconv('UTF-8', 'ASCII//TRANSLIT', utf8_encode($s));
