将英语引号替换为德语引号

问题描述

有没有一种方法可以实现德语引号(所谓的Gänsefüßchen")

is there a way to implement german quotes (so-called 'Gänsefüßchen')

„ („) and “ (")

在转换像

到

& bdquo只应在字符串的开头，而& ldquo则应在字符串的结尾.

the &bdquo should only apply at the beginning, the &ldquo at the end of an string.

推荐答案

此处是经过测试且可以正常运行的功能.

Here is the function, tested and works fine.

注意:& bdquo仅在字符串的开头应用，而在字符串的末尾仅使用& rdquo. (hsz的解决方案不遵循该规则)

Note: the &bdquo applies only at the beginning, the &rdquo only at the end of an string. (hsz's solution isn't following that rule)

function germanquotes($text){
    $size = strlen($text);
    $i=0;
    $replace = array();
    $replace['one'] = array();
    $replace['two'] = array();
    while($i < $size)
    {
        if($text[$i] == '"')
        {
            if($text[$i-1] == " " || empty($text[$i-1]))
            {
                    $replace['one'][] = $i;
            }
            elseif($text[$i+1] == " " || empty($text[$i+1]))
            {
                $replace['two'][] = $i;
            }
        }

        $i++;
    }

    $y = 0;
    $it = 0;
    foreach($replace['one'] as $ghh)
    {
        $text = substr_replace($text, '&bdquo;', ($ghh+$y), 1);
        $y += 6;
        $it++;
    }

    $to=0;
    $i=1;
    $u=1;
    foreach($replace['two'] as $ghhd)
    {
        $text = substr_replace($text, '&rdquo;', ($ghhd-1+$to+((8*$i)-($u*1))), 1);
        $i++;
        $u +=2;
        $to +=6;
    }

    return $text;
}

测试:

echo(germanquotes('I am "glad" to write "functions" for "stackoverflow" users'));
