I am making a swedish website, and swedish letters are å, ä, and ö.
我正在制作一个瑞典网站，瑞典字母是a, a, o。
I need to make a string entered by a user to become url-safe with PHP.
我需要创建一个用户输入的字符串，以使PHP成为url安全的。
Basically, need to convert all characters to underscore, all EXCEPT these:
基本上，需要将所有字符转换为下划线，除了这些:
A-Z, a-z, 1-9
and all swedish should be converted like this:
所有瑞典人都应该像这样转变:
'å' to 'a' and 'ä' to 'a' and 'ö' to 'o' (just remove the dots above).
“a”到“a”，“a”到“a”，“o”到“o”(去掉上面的点)。
The rest should become underscores as I said.
剩下的应该像我说的那样成为下划线。
Im not good at regular expressions so I would appreciate the help guys!
我不擅长正则表达式，所以我很感激那些帮忙的人!
Thanks
谢谢
NOTE: NOT URLENCODE...I need to store it in a database... etc etc, urlencode wont work for me.
注意:不是URLENCODE……我需要将它存储在数据库中……等等，urlencode对我没用。

// normalize data (remove accent marks) using PHP's *intl* extension
$data = normalizer_normalize($data);
// replace everything NOT in the sets you specified with an underscore
$data = preg_replace("#[^A-Za-z1-9]#","_", $data);

This should be useful which handles almost all the cases.
这对于处理几乎所有的情况应该是有用的。
function Unaccent($string)
{
return preg_replace('~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml|caron);~i', '$1', htmlentities($string, ENT_COMPAT, 'UTF-8'));

Use iconv to convert strings from a given encoding to ASCII, then replace non-alphanumeric characters using preg_replace:
使用iconv将给定编码的字符串转换为ASCII，然后使用preg_replace替换非字母数字字符:
$input = 'räksmörgås och köttbullar'; // UTF8 encoded
$input = iconv('UTF-8', 'ASCII//TRANSLIT', $input);
$input = preg_replace('/[^a-zA-Z0-9]/', '_', $input);
echo $input;
Result:

Use preg_replace() with a pattern of [\W] (i.o.w: any character which doesn't match letters, digits or underscore) to replace them by underscores.
使用preg_replace()模式为[\W] (i.o)。w:任何不匹配字母、数字或下划线的字符都可以用下划线代替。
Final result should look like:
最终结果应如下:
$data = preg_replace('[\W]', '_', normalizer_normalize($data));

If you're just interested in making things URL safe, then you want urlencode.
如果你只想让东西的URL安全，那么你需要urlencode。
Returns a string in which all non-alphanumeric characters except -_. have been replaced with a percent (%) sign followed by two hex digits and spaces encoded as plus (+) signs. It is encoded the same way that the posted data from a WWW form is encoded, that is the same way as in application/x-www-form-urlencoded media type. This differs from the » RFC 1738 encoding (see rawurlencode()) in that for historical reasons, spaces are encoded as plus (+) signs.
返回一个字符串，其中除-_之外所有非字母数字字符。用百分号(%)和两个十六进制数字以及加号(+)符号编码的空格替换。它的编码方式与来自WWW表单的已发布数据的编码方式相同，这与应用程序/x- WWW -form- urlencoding媒体类型的编码方式相同。这与»RFC 1738编码(参见rawurlencode())不同，因为历史原因，空格被编码为+(+)符号。
If you really want to strip all non A-Z, a-z, 1-9 (what's wrong with 0, by the way?), then you want:
如果你真的想去掉所有的非A-Z, A-Z, 1-9(顺便问一下，0有什么问题?)
$mynewstring = preg_replace('/[^A-Za-z1-9]/', '', $str);

as simple as
那么简单
$str = str_replace(array('å', 'ä', 'ö'), array('a', 'a', 'o'), $str);
$str = preg_replace('/[^a-z0-9]+/', '_', strtolower($str));
assuming you use the same encoding for your data and your code.
假设您对数据和代码使用相同的编码。

You don't need fancy regexps to filter the swedish chars, just use the strtr function to "translate" them, like:
您不需要华丽的regexp来过滤瑞典chars，只需使用strtr函数来“翻译”它们，比如:
$your_URL = "www.mäåö.com";
$good_URL = strtr($your_URL, "äåöë etc...", "aaoe etc...");
echo $good_URL;
->output: www.maao.com :)

If intl php extension is enabled, you can use Transliterator like this :
如果启用了intl php扩展，可以使用如下的音译器:
protected function removeDiacritics($string)
{
$transliterator = \Transliterator::create('NFD; [:Nonspacing Mark:] Remove; NFC;');
return $transliterator->transliterate($string);
}
To remove other special chars (not diacritics only like 'æ')
删除其他特殊字符(不区分标志只喜欢“æ”)
protected function removeDiacritics($string)
{
$transliterator = \Transliterator::createFromRules(
':: Any-Latin; :: Latin-ASCII; :: NFD; :: [:Nonspacing Mark:] Remove; :: NFC;',
\Transliterator::FORWARD
);
return $transliterator->transliterate($string);
