在哪里可以找到PHP音译器(Intl)的ID或规则列表? [英] Where can I find a list of IDs or rules for the PHP transliterator (Intl)?

问题描述

Transliterator::listIDs() 将列出ID，但显然不是完整列表.

Transliterator::listIDs() will list IDs, but apparently it's not a complete list.

在此页面上的示例中，该ID如下:

In the example from this page, the ID looks like:

Any-Latin; NFD; [:Nonspacing Mark:] Remove; NFC; [:Punctuation:] Remove; Lower();

有点奇怪，因为ID应该是唯一的.这看起来更像一条规则，但是如果我将其传递给createFromRules方法:)

which is kind of weird, because IDs are supposed to be unique. This looks more like a rule, but it doesn't work if I pass it to the createFromRules method :)

无论如何，我正在尝试从字符串中删除除破折号(-)或特定列表中的字符之外的所有标点符号.

Anyway, I'm trying to remove any punctuation from the string, except dash (-), or characters from a specific list.

您知道是否可行?还是有一些文档可以更好地解释音译器的语法?

Do you know if that's possible? Or is there some documentation that better explains the syntax for the transliterator ?

推荐答案

ICU文档.

您还可以使用 Transliterator::createFromRules() 创建自己的规则

You can also create your own rules with Transliterator::createFromRules().

您可以查看预定义的规则:

You can take a look at the prefefined rules:

<?php
$a = new ResourceBundle(NULL, sprintf('icudt%dl-translit', INTL_ICU_VERSION), true);

foreach ($a['RuleBasedTransliteratorIDs'] as $name => $v) {
    $file = @$v['file'];
    if (!$file) {
        $file = $v['internal'];
        echo $name, " (direction $file[direction]; internal)\n";
    } else { 
        echo $name, " (direction: $file[direction])\n";
        echo $file['resource'];
    }
    echo "\n--------------\n";
}

格式化后，结果类似于此.

After formatting, the result looks like this.
