我正在尝试从PHP字符串中的字符中删除重音，作为使字符串在URL中可用的第一步。
我正在使用以下代码：
$input = "Fóø Bår";
setlocale(LC_ALL, "en_US.utf8");
$output = iconv("utf-8", "ascii//TRANSLIT", $input);
print($output);
我期望的输出是这样的：
F'oo Bar
但是，不是重音字符被音译，而是用问号代替：
F?? B?r
我在网上找到的所有内容都表明设置语言环境可以解决这个问题，但我已经这样做了。我已经检查了以下细节：
locale -a生成的列表中）iconv -l生成的列表中）支持源编码和目标编码（UTF-8和ASCII）mb_check_encoding函数进行验证，如answer by mercator中所述）setlocale的调用成功（它返回'en_US.utf8'而不是FALSE）服务器正在使用iconv的错误实现。它具有 glibc 版本，而不是必需的 libiconv 版本。
请注意，某些系统上的iconv功能可能无法正常工作。在这种情况下，安装GNU libiconv库是个好主意。它最有可能最终得到更一致的结果 - PHP manual's introduction to iconv
有关PHP使用的iconv实现的详细信息包含在phpinfo函数的输出中。
（我无法使用正在为此项目工作的服务器上的正确iconv库重新编译PHP，因此下面我接受的答案是在没有iconv的情况下删除重音的最有用的答案支持。）

使用iconv时，必须设置参数区域设置：

echo iconv('utf8', 'ascii//TRANSLIT', $text);

test_enc();
setlocale(LC_ALL, 'cs_CZ.utf8');
test_enc();
setlocale(LC_ALL, 'en_US.utf8');
test_enc();

您可以使用urlencode。不是你想要的（删除重音），但会给你一个url可用的字符串
$output = urlencode ($input);
在Perl中我可以使用翻译正则表达式，但我不能想到PHP等价物
$input =~ tr/áâàå/aaaa/;
等...
你可以使用preg_replace
来做到这一点$patterns[0] = '/[á|â|à|å|ä]/';
$patterns[1] = '/[ð|é|ê|è|ë]/';
$patterns[2] = '/[í|î|ì|ï]/';
$patterns[3] = '/[ó|ô|ò|ø|õ|ö]/';
$patterns[4] = '/[ú|û|ù|ü]/';
$patterns[5] = '/æ/';
$patterns[6] = '/ç/';
$patterns[7] = '/ß/';
$replacements[0] = 'a';
$replacements[1] = 'e';
$replacements[2] = 'i';
$replacements[3] = 'o';
$replacements[4] = 'u';
$replacements[5] = 'ae';
$replacements[6] = 'c';
$replacements[7] = 'ss';
$output = preg_replace($patterns, $replacements, $input);

您究竟是如何使用mb_detect_encoding()来验证字符串实际上是UTF-8？
如果我只是在你的字符串的UTF-8和ISO-8859-1编码版本上调用mb_detect_encoding($input)，它们都返回“UTF-8”，因此该功能不是特别可靠。 / p>
iconv()在获取错误编码的字符串并且仅回显“F”时给我一个PHP“通知”，但这可能只是因为不同的PHP / iconv设置/版本（？）。

我同意乔治布罗克的评论。
如果您找到了让TRANSLIT工作的方法，您可以构建友好的URL：
$url = preg_replace( '/(\w)[^\w\s](\w)/', '$1$2', $url ); $url = preg_replace( '/[^a-z0-9]+/', '-', $url ); $url = preg_replace( '-'，例如'/(?:(^|\-)\-+|\-$)/', '', $url ); 如果你无法让它工作，请用基于strtr /字符的替换替换setp 1，例如Xetius的解决方案。

如果主要任务只是使用URL中的字符串，为什么不使用slugyfier？
composer require cocur/slugify
然后
use Cocur\Slugify\Slugify;
$slugify = new Slugify();
echo $slugify->slugify('Fóø Bår');
它也有许多流行框架的桥梁。例如。您可以使用Doctrine Extensions Sluggable行为为数据库中的每个实体自动生成唯一的子弹，并在URL中使用它。
如果您只想消除所有重音，可以使用rulesets来满足要求。

在laravel中，您只需使用str_slug($accentedPhrase)
并且如果您担心用破折号（-）将此方法替换为空格，则可以使用str_replace('-', ' ', str_slug($accentedPhrase))

这个答案我在这里有以下提示，所以它不是我的。它适合我使用LATIN1或UTF-8。如果使用其他字符集，则可能应将它们添加到mb_detect_encoding函数中。可能还需要正确的环境设置。
function NoAccents($s){
return iconv(mb_detect_encoding($s,'UTF-8, ASCII, ISO-8859-1'),'ASCII//TRANSLIT//INGORE',$s);
}

这是怎么了？适用于UTF8
function strip_accents($s){
return str_replace(
explode(' ', preg_replace('/ +/', ' ', 'č ć ž š đ Č Ć Ž Š Đ à á â ã ä ç è é ê ë ì í î ï ñ ò ó ô õ ö ù ú û ü ý ÿ À Á Â Ã Ä Ç È É Ê Ë Ì Í Î Ï Ñ Ò Ó Ô Õ Ö Ù Ú Û Ü Ý')),
explode(' ', preg_replace('/ +/', ' ', 'c c z s dj C C Z S DJ a a a a a c e e e e i i i i n o o o o o u u u u y y A A A A A C E E E E I I I I N O O O O O U U U U Y')),
$s);
}
不使用preg_replace可以更快，但是速度不是我的目标。

基于@Mimouni答案，我进行了此功能，以将重音符号音译为非重音符号。
/**
* @param $str Convert string to lowercase and replace special chars to equivalents ou remove its
* @return string
*/
function _slugify(string $string): string
{
$str = $string; // for comparisons
$str = _toUtf8($str); // Force to work with string in UTF-8
$str = iconv('UTF-8', 'ASCII//TRANSLIT', $str);
if ($str != htmlentities($string, ENT_QUOTES, 'UTF-8')) { // iconv fails
$str = _toUtf8($string);
$str = htmlentities($str, ENT_QUOTES, 'UTF-8');
$str = preg_replace('#&([a-z]{1,2})(acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);#i', '$1', $str);
// Need to strip non ASCII chars or any other than a-z, A-Z, 0-9...
$str = html_entity_decode($str, ENT_QUOTES, 'UTF-8');
$str = preg_replace(array('#[^0-9a-z]#i', '#[ -]+#'), ' ', $str);
$str = trim($str, ' -');
}
// lowercase
$string = strtolower($str);
return $string;
}
要将字符串转换为UTF-8，在这里我使用“多字节字符串”扩展名。 请注意，为了避免出现混合内容（我遇到这种情况）的麻烦，我将字符串分成几部分，然后逐字转换。
/**
* @param $str string String in any encoding
* @return string
*/
function _toUtf8(string $str_in): ?string
{
if (!function_exists('mb_detect_encoding')) {
throw new \Exception('The Multi Byte String extension is absent!');
}
$str_out = [];
$words = explode(" ", $str_in);
foreach ($words as $word) {
$current_encoding = mb_detect_encoding($word, 'UTF-8, ASCII, ISO-8859-1');
$str_out[] = mb_convert_encoding($word, 'UTF-8', $current_encoding);
}
return implode(" ", $str_out);
}

另外，您以UTF-8部分保存解码/编码。
答案 23 :(得分：-1)
WordPress的实现绝对是UTF8字符串最安全的。对于Latin1字符串，一个简单的strtr可以完成这项工作，但确保您将脚本保存为LATIN1格式，而不是UTF-8。
答案 24 :(得分：-1)
我在网上偶然发现的一个技巧是使用htmlentities然后剥离编码字符：
$stripped = preg_replace('`&[^;]+;`','',htmlentities($string));
不完美但在某些情况下确实效果很好。
但是，您正在撰写有关创建网址字符串的文章，因此urlencode及其对应的urldecode可能会更好。或者，如果要创建查询字符串，请使用最后一个函数：http_build_query。
