替换重音字符

我正在尝试替换重音字符与正常的替换。以下是我目前正在做什么。

    $string = "Éric Cantona";
$strict = strtolower($string);


echo "After Lower: ".$strict;


$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';


$strict = preg_replace($patterns, $replacements, $strict);
echo "Final: ".$strict;

这给了我:

    After Lower: éric cantona
Final: ric cantona

以上给我 ric cantona我想输出为 eric cantona

有人能告诉我哪里出了问题吗?

strtolower仅适用于 iso-8859-1编码的字符串。您可以尝试使用 mb_strtolower

或者,如果你不得不使用多字节扩展,你也可以使用 iconv 的音译支持:

iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text);

编辑:

看来我有点太快了。您似乎使用的是 iso-8859-1,因此您目前的策略将起作用。只需正确编写 regexp 的。例子:

'/(ð|é|ê|è|ë)/'

不要:

'/[ð|é|ê|è|ë]/'

要删除变音符号,请使用 iconv:

$val = iconv('ISO-8859-1','ASCII//TRANSLIT',$val);

或者

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

请注意,php 有一些奇怪的 bug (有时?)需要有一个区域设置来使这些转换工作,使用 setlocale ()。

edit tested, it gets all of your diacritics out of the box:

$val = "á|â|à|å|ä ð|é|ê|è|ë í|î|ì|ï ó|ô|ò|ø|õ|ö ú|û|ù|ü æ ç ß abc ABC 123";
echo iconv('UTF-8','ASCII//TRANSLIT',$val);

产出(更新日期: 2019-12-30)

a|a|a|a|a d|e|e|e|e i|i|i|i o|o|o|o|o|o u|u|u|u ae c ss abc ABC 123

注意,ð被正确地音译为 d而不是 o,正如在已接受的答案中一样。

免责声明: 我不再支持这个回答了(我当时是盲人) ,但是谢谢你的赞成票 = P

你可以以此为基础,从 WordPress,用于生成漂亮的 url (入口点是 slugify ()函数) :

/**
* Converts all accent characters to ASCII characters.
*
* If there are no accent characters, then the string given is just returned.
*
* @param string $string Text that might have accent characters
* @return string Filtered string with replaced "nice" characters.
*/

if (!preg_match('/[\x80-\xff]/', $string))
return $string;
if (seems_utf8($string)) {

根据答案中列出的各种变化,我尝试了各种方法,但是下面的方法奏效了:

$unwanted_array = array(    'Š'=>'S', 'š'=>'s', 'Ž'=>'Z', 'ž'=>'z', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O', 'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U',
'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss', 'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c',
'è'=>'e', 'é'=>'e', 'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o', 'ô'=>'o', 'õ'=>'o',
'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'þ'=>'b', 'ÿ'=>'y' );
$str = strtr( $str, $unwanted_array );

所以我在 php.net 页面上找到了 preg _ place 函数

// replace accented chars


$string = "Zacarías Ferreíra"; // my definition for string variable
$accents = '/&([A-Za-z]{1,2})(grave|acute|circ|cedil|uml|lig);/';


$string_encoded = htmlentities($string,ENT_NOQUOTES,'UTF-8');


$string = preg_replace($accents,'$1',$string_encoded);

如果你有编码问题,你可能会得到这样的“ Zacarí Âas Ferrei旋风”,只要解码字符串,并使用上述代码

$string = utf8_decode("Zacarías Ferreíra");

我刚从蜥蜴那里得到了答案,这个答案非常有帮助——特别是当你做一些排序的时候。不是美丽多少字符我们需要说大致相同;)

注意一些关于德语元音变调(ä = > ae)的细微变化

编辑: 根据 user3682119(版权符号除外)和 daker 的评论添加更多字符。

我知道,这个问题很久以前就有人问过了。

我一直在寻找一个简短而优雅的解决方案,但由于两个原因而无法找到满足感:

首先,大多数现有的解决方案用其他字符的列表替换字符列表。不幸的是,它需要为 php 脚本文件本身使用特定的编码,这可能是不需要的。

Second, using iconv seems to be a good way, but it's not enough as the result of a converted character could be one or two characters, or a Fatal Exception.

所以我写了一个小函数:

function replaceAccent($string, $replacement = '_')
{
$alnumPattern = '/^[a-zA-Z0-9 ]+$/';


if (preg_match($alnumPattern, $string)) {
return $string;
}


$ret = array_map(
function ($chr) use ($alnumPattern, $replacement) {
if (preg_match($alnumPattern, $chr)) {
return $chr;
} else {
$chr = @iconv('ISO-8859-1', 'ASCII//TRANSLIT', $chr);
if (strlen($chr) == 1) {
return $chr;
} elseif (strlen($chr) > 1) {
$ret = '';
foreach (str_split($chr) as $char2) {
if (preg_match($alnumPattern, $char2)) {
$ret .= $char2;
}
}
return $ret;
} else {
// replace whatever iconv fail to convert by something else
return $replacement;
}
}
},
str_split($string)
);


return implode($ret);
}
protected $_convertTable = array(

From magento, im using it for basically everything

在 PHP 5.4中,intl扩展提供了一个名为 TransLiterator 的新类。

我认为这是消除变音符号的最好方法,原因有二:

  1. 音译器是基于 ICU 的,所以你使用的是 ICU 图书馆的表格。ICU 是一个伟大的项目,经过一年的发展,提供全面的表格和功能。无论你自己写什么桌子,它永远不会像 ICU 的桌子那么完整。

  2. 在 UTF-8中,字符可以用不同的方式表示。例如,字符 ñ 可以保存为单个(多字节)字符,或者作为字符 ˜(多字节)和 n的组合。除此之外,Unicode 中的一些字符是同形字: 它们看起来相同,但有不同的代码点。因此,规范化字符串也很重要。

下面是一段取自 我的一个老答案的示例代码:

<?php
$transliterator = Transliterator::createFromRules(':: NFD; :: [:Nonspacing Mark:] Remove; :: NFC;', Transliterator::FORWARD);
$test = ['abcd', 'èe', '€', 'àòùìéëü', 'àòùìéëü', 'tiësto'];
foreach($test as $e) {
$normalized = $transliterator->transliterate($e);
echo $e. ' --> '.$normalized."\n";
}
?>

结果:

abcd --> abcd
èe --> ee
€ --> €
àòùìéëü --> aouieeu
àòùìéëü --> aouieeu
tiësto --> tiesto

TransLiterator 类的第一个参数执行变量删除以及字符串的规范化。

echo $normalized = $transliterator->transliterate($string);

在 ubuntu 中安装 php 扩展:

apt-get install php-intl

Don't forget, in composer, to require the extension ext-intl to ensure it properly fits into deployed systems.

这对我很有效:

<?php
setlocale(LC_ALL, "en_US.utf8");
$val = iconv('UTF-8','ASCII//TRANSLIT',$val);
?>

我已经搜索和你的想法重音条纹是非常棒的和成本效益,但你的正则表达式是错误的,错过了两个额外的参数。长话短说正则表达式必须是:

$patterns[0] = '/[áâàåä]/ui';
$patterns[1] = '/[ðéêèë]/ui';
$patterns[2] = '/[íîìï]/ui';
$patterns[3] = '/[óôòøõö]/ui';
$patterns[4] = '/[úûùü]/ui';
$patterns[5] = '/æ/ui';
$patterns[6] = '/ç/ui';
$patterns[7] = '/ß/ui';
$replacements[0] = 'a';
$replacements[1] = 'e';
$replacements[2] = 'i';
$replacements[3] = 'o';
$replacements[4] = 'u';
$replacements[5] = 'ae';
$replacements[6] = 'c';
$replacements[7] = 'ss';

正如您所看到的,它们非常相似,但是最重要的是正则表达式第二个斜杠后面的参数。当一个正则表达式类似于这个 /[someCoolRegex]/ui时,u指定它必须使用 unicode,而 i指定它不区分大小写,我已经测试了我自己的表达式,在这个 论坛中的回答,我必须说比使用 strtr 更具成本效益。

希望有人看到这个答案。

作为一个替代方案(本质上比较复杂) ,看看 wordpress 是如何去除重音的。在下面做了一些修改,使它能够独立运行,而不需要引用 wordpress 函数。

     function mbstring_binary_safe_encoding($reset = false)
{
static $encodings  = array();
static $overloaded = null;


if (is_null($overloaded)) {
$overloaded = function_exists('mb_internal_encoding') && (ini_get('mbstring.func_overload') & 2);
}


if (false === $overloaded) {
return;
}


if (!$reset) {
$encoding = mb_internal_encoding();
array_push($encodings, $encoding);
mb_internal_encoding('ISO-8859-1');
}


if ($reset && $encodings) {
$encoding = array_pop($encodings);

您可以使用 PHP Strtr ()函数来去除重音字符:

$string = "Éric Cantona";
$accented_array = array('Š'=>'S', 'š'=>'s', 'Ž'=>'Z', 'ž'=>'z', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E','Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O', 'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U','Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss', 'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c','è'=>'e', 'é'=>'e', 'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o', 'ô'=>'o', 'õ'=>'o','ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'þ'=>'b', 'ÿ'=>'y' );


$required_str = strtr( $string, $accented_array );

我发现这是一个很好的方法,不用太担心字符集和数组,或者 iconv:

function replace_accents($str) {
$str = htmlentities($str, ENT_COMPAT, "UTF-8");
$str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde|ring);/','$1',$str);
return html_entity_decode($str);
}

对于所有想把这种元音变换成德语的人,他们可以使用这种方法:

public function handleGermanUmlauts(string $name) : string
{
// we need this line for preg_replace can work
$name = htmlentities($name, ENT_COMPAT, 'UTF-8');
// this line is adding `e` character instead of suffix, except for `ee`
$name = preg_replace('/&([a-df-zA-DF-Z])(uml|acute|grave|circ|tilde|ring);/', '$1e', $name);
// this line will make next line working for using iconv method
$name = html_entity_decode($name);
// with iconv we are transferring all other characters like EUR and etc.
$name = str_replace(array("\"", "'", "`", "^", "~"), "", iconv("utf-8", "ASCII//TRANSLIT", $name));


return $name;
}

嗯,我最喜欢的是一个函数,它替换了德语元音符号,然后使用 iconv。 如果你想要一个漂亮的 SEO 鼻涕虫,你可以使用例如“ Ä”作为“ ae”等。

function slugifyText($text) {
$arr1 = Array('ä','ö','ü','Ä','Ö','Ü','ß');
$arr2 = Array('ae', 'oe', 'ue', 'ae', 'oe', 'ue', 'ss');
$text = str_replace($arr1, $arr2, $text);
$text = iconv('UTF-8','ASCII//TRANSLIT',$text);
$text = preg_replace("/[^a-zA-Z0-9_-]/", "", strtolower($text));
return $text;
}
