将数字转换为强调的拼音?

cjk regex php

Philipp Lenssen · 技术社区 · 16 年前

给定一个源文本

nin2 hao3 ma

(这是一种典型的书写ASCII拼音的方法,没有适当的重音字符) 并给出一个(utf8)转换表

a1;Ä
e1;Ä
i1;Ä«
o1;Å
u1;Å«
Ã¼1;Ç
A1;Ä
E1;Ä
...

如何将源文本转换为

nÃn hÇo ma

为了我使用PHP的价值,这可能是我正在研究的regex?

<?php
$in = 'nin2 hao3 ma';
$out = 'nÃn hÇo ma';

function replacer($match) {
  static $trTable = array(
    1 => array(
      'a' => 'Ä',
      'e' => 'Ä',
      'i' => 'Ä«',
      'o' => 'Å',
      'u' => 'Å«',
      'Ã¼' => 'Ç',
      'A' => 'Ä',
      'E' => 'Ä'),
    2 => array('i' => 'Ã'),
    3 => array('a' => 'Ç')
  );
  list(, $word, $i) = $match;
  return str_replace(
    array_keys($trTable[$i]),
    array_values($trTable[$i]),
    $word); }

// Outputs: bool(true)
var_dump(preg_replace_callback('~(\w+)(\d+)~', 'replacer', $in) === $out);

奥利的算法是一个很好的开始,但它没有正确应用标记。例如,桥1变成了“Q_«”。这个是正确和完整的。您可以很容易地看到如何定义替换规则。

它对音调5也做了全部的事情,尽管它不影响输出,除了删除数字。我把它放在里面,以防你想用第5音做些什么。

该算法的工作原理如下:

单词和音调在$match[1]和[2]中提供。
字母后面加了一个星号,应该加上重音符号。
带有星号的字母被带有正确音调标记的字母代替。

例子:

qiao => (iao becomes ia*o) => qia*o => qiÇo

这个策略,以及 strtr (优先考虑较长的替换),确保不会发生这种情况:

巧1=>Q«


function pinyin_addaccents($string) {
    # Find words with a number behind them, and replace with callback fn.
    return preg_replace_callback(
        '~([a-zA-ZÃ¼Ã]+)(\d)~',
        'pinyin_addaccents_cb',
        $string);
}

# Helper callback
function pinyin_addaccents_cb($match) {
    static $accentmap = null;

    if( $accentmap === null ) {
        # Where to place the accent marks
        $stars =
            'a* e* i* o* u* Ã¼* '.
            'A* E* I* O* U* Ã* '.
            'a*i a*o e*i ia* ia*o ie* io* iu* '.
            'A*I A*O E*I IA* IA*O IE* IO* IU* '.
            'o*u ua* ua*i ue* ui* uo* Ã¼e* '.
            'O*U UA* UA*I UE* UI* UO* ÃE*';
        $nostars = str_replace('*', '', $stars);

        # Build an array like Array('a' => 'a*') and store statically
        $accentmap = array_combine(explode(' ',$nostars), explode(' ', $stars));
        unset($stars, $nostars);
    }

    static $vowels =
        Array('a*','e*','i*','o*','u*','Ã¼*','A*','E*','I*','O*','U*','Ã*');

    static $pinyin = Array(
        1 => Array('Ä','Ä','Ä«','Å','Å«','Ç','Ä','Ä','Äª','Å','Åª','Ç'),
        2 => Array('Ã¡','Ã©','Ã','Ã³','Ãº','Ç','Ã','Ã','Ã','Ã','Ã','Ç'),
        3 => Array('Ç','Ä','Ç','Ç','Ç','Ç','Ç','Ä','Ç','Ç','Ç','Ç'),
        4 => Array('Ã ','Ã¨','Ã¬','Ã²','Ã¹','Ç','Ã','Ã','Ã','Ã','Ã','Ç'),
        5 => Array('a','e','i','o','u','Ã¼','A','E','I','O','U','Ã')
    );

    list(,$word,$tone) = $match;
    # Add star to vowelcluster
    $word = strtr($word, $accentmap);
    # Replace starred letter with accented 
    $word = str_replace($vowels, $pinyin[$tone], $word);
    return $word;
}

要添加JavaScript解决方案,请执行以下操作:

此代码根据放置一个的官方算法放置音调标记, 看见 wikipedia .

希望对你们中的一些人有所帮助,建议和改进会很好!
