PHP: Replace umlauts with closest 7-bit ASCII equivalent in an UTF-8 string
提问by BlaM
What I want to do is to remove all accents and umlauts from a string, turning "l?rm" into "larm" or "andré" into "andre". What I tried to do was to utf8_decode the string and then use strtr on it, but since my source file is saved as UTF-8 file, I can't enter the ISO-8859-15 characters for all umlauts - the editor inserts the UTF-8 characters.
我想要做的是从字符串中删除所有重音和元音变音，将“l?rm”变成“larm”或“andré”变成“andre”。我试图做的是对字符串进行 utf8_decode，然后在其上使用 strtr，但是由于我的源文件保存为 UTF-8 文件，因此我无法为所有变音符号输入 ISO-8859-15 字符 - 编辑器插入UTF-8 字符。
Obviously a solution for this would be to have an include that's an ISO-8859-15 file, but there must be a better way than to have another required include?
显然，对此的解决方案是拥有一个 ISO-8859-15 文件的包含，但必须有比拥有另一个必需的包含更好的方法？
echo strtr(utf8_decode($input),
'???????￥μàá??????èéê?ìí??D?òó????ùú?üY?àáa?????èéê?ìí??e?òó????ùú?üy?',
'SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy');
UPDATE:Maybe I was a bit inaccurate with what I try to do: I do not actually want to remove the umlauts, but to replace them with their closest "one character ASCII" equivalent.
更新：也许我对我尝试做的事情有点不准确：我实际上并不想删除变音符号，而是用它们最接近的“一个字符 ASCII”等价物替换它们。

A little trick that doesn't require setting locales or having huge translation tables:
一个不需要设置语言环境或拥有庞大翻译表的小技巧：
function Unaccent($string)
{
if (strpos($string = htmlentities($string, ENT_QUOTES, 'UTF-8'), '&') !== false)
{
$string = html_entity_decode(preg_replace('~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|tilde|uml);~i', '', $string), ENT_QUOTES, 'UTF-8');
}
return $string;
}
The only requirement for it to work properly is to save your files in UTF-8 (as you should already).
它正常工作的唯一要求是将您的文件保存为 UTF-8（您应该已经这样做了）。

you can also try this
你也可以试试这个
$string = "Fó? B?r";
$transliterator = Transliterator::createFromRules(':: Any-Latin; :: Latin-ASCII; :: NFD; :: [:Nonspacing Mark:] Remove; :: Lower(); :: NFC;', Transliterator::FORWARD);
echo $normalized = $transliterator->transliterate($string);
but you need to have http://php.net/manual/en/book.intl.phpavailable

I found that this one gives the most consistent results in French and German.
with the meta tag set to utf-8, I have place it in a function to return a line from a array of words and it works perfect.
我发现这个在法语和德语中给出了最一致的结果。将元标记设置为utf-8，我将它放在一个函数中，以从一组单词中返回一行，并且效果很好。
htmlentities ( $line, ENT_SUBSTITUTE , 'utf-8' )

If you are using WordPress, you can use the built-in function remove_accents( $string )
如果您使用的是 WordPress，则可以使用内置功能 remove_accents( $string )

However I noticed a bug : it doesn't work on a string with a single character.
但是我注意到一个错误：它不适用于具有单个字符的字符串。

For Arabic and Persian users i recommend this way to remove diacritics:
对于阿拉伯语和波斯语用户，我建议通过这种方式删除变音符号：
$diacritics = array('?','?','?','?','?','?','?','?');
$search_txt = str_replace($diacritics, '', $diacritics);
For typing diacritics in Arabic keyboards u can use this Asci(those codes are Asci not Unicode) codes in windows editors typing diacritics directly or holding Alt + (type the code of diacritic character) This is the codes
要在阿拉伯语键盘中输入变音符号，您可以在 Windows 编辑器中使用此 Asci（这些代码是 Asci 而非 Unicode）代码直接输入变音符号或按住 Alt +（输入变音符号字符的代码）这是代码

Okay, found an obvious solution myself, but it's not the best concerning performance...
好的，我自己找到了一个明显的解决方案，但这并不是最好的性能......
echo strtr(utf8_decode($input),
utf8_decode('???????￥μàá??????èéê?ìí??D?òó????ùú?üY?àáa?????èéê?ìí??e?òó????ùú?üy?'),
'SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy');
