PHP: Dealing special characters with iconv
提问by laukok
I still don't understand how iconvworks.
我仍然不明白是如何iconv工作的。
For instance,
例如，
$string = "L?ic & René";
$output = iconv("UTF-8", "ISO-8859-1//TRANSLIT", $string);
I get,
我明白了，
Notice: iconv() [function.iconv]: Detected an illegal character in input string in...
注意： iconv() [function.iconv]: 在输入字符串中检测到非法字符...
$string = "L?ic";or $string = "René";
$string = "L?ic";或者 $string = "René";
I get,
我明白了，
Notice: iconv() [function.iconv]:Detected an incomplete multibyte character in input string in.
注意：iconv() [function.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 = "&";
我一无所获 $string = "&";
There are two sets of different outputs I need store them in the two different columns inside the table of my database,
我需要将两组不同的输出存储在数据库表内的两个不同列中，
I need to convert
L?ic & RenétoLoic & Renefor clean url purposes.I need to keep them as they are -
L?ic & RenéasL?ic & Renéthen only convert them withhtmlentities($string, ENT_QUOTES);when displaying them on my html page.
我需要转换
L?ic & René到Loic & Rene清洁网址的目的。我需要保持它们原样 -
L?ic & René因为L?ic & René只有htmlentities($string, ENT_QUOTES);在我的 html 页面上显示它们时才将它们转换。
I tried with some of the suggestions in php.netbelow, but still don't work,
我尝试了下面php.net中的一些建议，但仍然不起作用，
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.
我遇到过需要音译某些字符的情况，但其他字符却被忽略了（对于 ayn 或 hamza 等奇怪的变音符号）。添加 //TRANSLIT//IGNORE 似乎对我有用。它会音译所有可以音译的东西，然后丢弃不能音译的东西。
So:
所以：
$string = "?ABBāSāBāD";
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,
而另一个，

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?
我怎样才能真正解决它们？
Thanks.
谢谢。

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.
您是否以 UTF-8 编码保存了源文件？如果没有（我猜你没有，因为这会产生“不完整的多字节字符”错误），然后先尝试。

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