转换UTF8文本以在URL中使用 [英] Converting UTF8 text for use in a URL

问题描述

我正在开发一个使用UTF8来显示非英文字符的国际站点.我还使用了包含项目名称的友好URL.显然，我不能在URL中使用非英文字符.

I'm developing an international site which uses UTF8 to display non english characters. I'm also using friendly URLS which contain the item name. Obviously I can't use the non english characters in the URL.

此转换是否有某种常见的做法?我不确定应该用哪个英文字符替换它们.有些很明显(如è到e)，但有些我不熟悉的字符(如ß).

Is there some sort of common practice for this conversion? I'm not sure which english characters i should be replacing them with. Some are quite obvious (like è to e) but other characters I am not familiar with (such as ß).

推荐答案

我通常将 iconv()与'ASCII//TRANSLIT'选项.输入如下内容:

I normally use iconv() with the 'ASCII//TRANSLIT' option. This takes input like:

último año

并产生如下输出:

'ultimo a~no

然后我使用preg_replace()用破折号替换空白:

Then I use preg_replace() to replace white spaces with dashes:

'ultimo-a~no

...并删除不需要的字符，例如

... and remove unwanted chars, e.g.

[^a-z0-9-]

它对于阿拉伯语或中文可能没有用，但对西班牙语，法语或德语的效果很好.

It's probably useless with Arabic or Chinese but it works fine with Spanish, French or German.
