如何从PHP字符串中的字符中删除重音？

时间：2009-06-19 12:06:49

标签： php iconv

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：

  1. 我设置的区域设置由服务器支持（包含在locale -a生成的列表中）
  2. 服务器的iconv版本（包含在iconv -l生成的列表中）支持源编码和目标编码（UTF-8和ASCII）
  3. 输入字符串采用UTF-8编码（使用PHP的mb_check_encoding函数进行验证，如answer by mercator中所述）
  4. 对setlocale的调用成功（它返回'en_US.utf8'而不是FALSE）

    5. 问题的原因：

    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。）

这是我经常使用的一段代码：

function stripAccents($stripAccents){
  return strtr($stripAccents,'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ','aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY');
}

答案 2 :(得分：29)

Gino上面发布的简单函数的UTF-8友好版：

function stripAccents($str) {
    return strtr(utf8_decode($str), utf8_decode('àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ'), 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY');
}

因为我的php文件是UTF-8编码而不得不这样做。

希望它有所帮助。

使用iconv时，必须设置参数区域设置：

function test_enc($text = 'ěščřžýáíé ĚŠČŘŽÝÁÍÉ fóø bår FÓØ BÅR æ')
{
    echo '<tt>';
    echo iconv('utf8', 'ascii//TRANSLIT', $text);
    echo '</tt><br/>';
} 

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

收益率：

????????? ????????? f?? b?r F?? B?R ae
escrzyaie ESCRZYAIE fo? bar FO? BAR ae
escrzyaie ESCRZYAIE fo? bar FO? BAR ae

另一个语言环境，然后cs_CZ和en_US我还没有安装，我无法测试它。

在C＃中，我看到使用转换为unicode规范化形式的解决方案 - 重音被分割出来，然后通过非间隔unicode类别进行过滤。

答案 7 :(得分：5)

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);

（请注意，这是从周五中午记忆后的迷雾啤酒中输入的，所以可能不是100％正确）

或者你可以制作一个哈希表并根据它进行替换。

答案 8 :(得分：5)

我认为这里的问题是你的编码将ä和å不同的符号视为'a'。实际上，strtr的PHP文档提供了一个用于删除重音的示例：（

答案 9 :(得分：2)

我无法重现你的问题。我得到了预期的结果。

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（？）。

我建议您首先尝试调用mb_check_encoding($input, "utf-8")来验证字符串确实是否为UTF-8。 我认为可能不是。

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：

  1. 使用iconv和//TRANSLITñ=＆gt; N〜
    • 删除字词内的非字母数字非空格字符：$url = preg_replace( '/(\w)[^\w\s](\w)/', '$1$2', $url );
    • 替换剩余的分色：$url = preg_replace( '/[^a-z0-9]+/', '-', $url );
    • 删除double / leading / traling：$url = preg_replace( '-'，例如'/(?:(^|\-)\-+|\-$)/', '', $url );

    2. 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。

我刚刚根据这个线程的读取创建了一个removeAccents方法，另一个也是How to remove accents and turn letters into "plain" ASCII characters?）。

方法在这里：https://github.com/lingtalfi/Bat/blob/master/StringTool.md#removeaccents

测试在这里：https://github.com/lingtalfi/Bat/blob/master/btests/StringTool/removeAccents/stringTool.removeAccents.test.php，

这是迄今为止测试的内容：

$a = [
    // easy
    '',
    'a',
    'après',
    'dédé fait la fête ?',
    // hard
    'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ',

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')),

    $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);
}

$accentsRemoved = strtr( $stringToRemoveAccents , $unwanted_array );

答案 22 :(得分：0)

您可以使用数组键=＆gt;与UTF-8字符安全地使用strtr（）的值样式，即使它们是多字节的。

function no_accent($str){
    $accents = array('À' => 'A', 'Á' => 'A', 'Â' => 'A', 'Ã' => 'A', 'Ä' => 'A', 'Å' => 'A', 'à' => 'a', 'á' => 'a', 'â' => 'a', 'ã' => 'a', 'ä' => 'a', 'å' => 'a', 'Ā' => 'A', 'ā' => 'a', 'Ă' => 'A', 'ă' => 'a', 'Ą' => 'A', 'ą' => 'a', 'Ç' => 'C', 'ç' => 'c', 'Ć' => 'C', 'ć' => 'c', 'Ĉ' => 'C', 'ĉ' => 'c', 'Ċ' => 'C', 'ċ' => 'c', 'Č' => 'C', 'č' => 'c', 'Ð' => 'D', 'ð' => 'd', 'Ď' => 'D', 'ď' => 'd', 'Đ' => 'D', 'đ' => 'd', 'È' => 'E', 'É' => 'E', 'Ê' => 'E', 'Ë' => 'E', 'è' => 'e', 'é' => 'e', 'ê' => 'e', 'ë' => 'e', 'Ē' => 'E', 'ē' => 'e', 'Ĕ' => 'E', 'ĕ' => 'e', 'Ė' => 'E', 'ė' => 'e', 'Ę' => 'E', 'ę' => 'e', 'Ě' => 'E', 'ě' => 'e', 'Ĝ' => 'G', 'ĝ' => 'g', 'Ğ' => 'G', 'ğ' => 'g', 'Ġ' => 'G', 'ġ' => 'g', 'Ģ' => 'G', 'ģ' => 'g', 'Ĥ' => 'H', 'ĥ' => 'h', 'Ħ' => 'H', 'ħ' => 'h', 'Ì' => 'I', 'Í' => 'I', 'Î' => 'I', 'Ï' => 'I', 'ì' => 'i', 'í' => 'i', 'î' => 'i', 'ï' => 'i', 'Ĩ' => 'I', 'ĩ' => 'i', 'Ī' => 'I', 'ī' => 'i', 'Ĭ' => 'I', 'ĭ' => 'i', 'Į' => 'I', 'į' => 'i', 'İ' => 'I', 'ı' => 'i', 'Ĵ' => 'J', 'ĵ' => 'j', 'Ķ' => 'K', 'ķ' => 'k', 'ĸ' => 'k', 'Ĺ' => 'L', 'ĺ' => 'l', 'Ļ' => 'L', 'ļ' => 'l', 'Ľ' => 'L', 'ľ' => 'l', 'Ŀ' => 'L', 'ŀ' => 'l', 'Ł' => 'L', 'ł' => 'l', 'Ñ' => 'N', 'ñ' => 'n', 'Ń' => 'N', 'ń' => 'n', 'Ņ' => 'N', 'ņ' => 'n', 'Ň' => 'N', 'ň' => 'n', 'ʼn' => 'n', 'Ŋ' => 'N', 'ŋ' => 'n', 'Ò' => 'O', 'Ó' => 'O', 'Ô' => 'O', 'Õ' => 'O', 'Ö' => 'O', 'Ø' => 'O', 'ò' => 'o', 'ó' => 'o', 'ô' => 'o', 'õ' => 'o', 'ö' => 'o', 'ø' => 'o', 'Ō' => 'O', 'ō' => 'o', 'Ŏ' => 'O', 'ŏ' => 'o', 'Ő' => 'O', 'ő' => 'o', 'Ŕ' => 'R', 'ŕ' => 'r', 'Ŗ' => 'R', 'ŗ' => 'r', 'Ř' => 'R', 'ř' => 'r', 'Ś' => 'S', 'ś' => 's', 'Ŝ' => 'S', 'ŝ' => 's', 'Ş' => 'S', 'ş' => 's', 'Š' => 'S', 'š' => 's', 'ſ' => 's', 'Ţ' => 'T', 'ţ' => 't', 'Ť' => 'T', 'ť' => 't', 'Ŧ' => 'T', 'ŧ' => 't', 'Ù' => 'U', 'Ú' => 'U', 'Û' => 'U', 'Ü' => 'U', 'ù' => 'u', 'ú' => 'u', 'û' => 'u', 'ü' => 'u', 'Ũ' => 'U', 'ũ' => 'u', 'Ū' => 'U', 'ū' => 'u', 'Ŭ' => 'U', 'ŭ' => 'u', 'Ů' => 'U', 'ů' => 'u', 'Ű' => 'U', 'ű' => 'u', 'Ų' => 'U', 'ų' => 'u', 'Ŵ' => 'W', 'ŵ' => 'w', 'Ý' => 'Y', 'ý' => 'y', 'ÿ' => 'y', 'Ŷ' => 'Y', 'ŷ' => 'y', 'Ÿ' => 'Y', 'Ź' => 'Z', 'ź' => 'z', 'Ż' => 'Z', 'ż' => 'z', 'Ž' => 'Z', 'ž' => 'z');
    return strtr($str, $accents);
}

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。
