� 来自 ldap 的字符

Question

当我搜索某些用户时，我从 ldap 服务器收到一些奇怪的字符 info.if 值包含土耳其语字符，如“ç”，它替换为“�”。在这种情况下，我将字符串转换为 utf-8 比str_replace 修复 it.My 函数是这样的；

 function utf8char($str) {     
    $search = array('Ý','ý', 'þ' ,'Þ' ,'ð','Ð');
    $replace = array('İ' ,'ı' ,'ş','Ş','ğ','Ğ');
    return str_replace($search, $replace, $str);
}

但有时这会导致一些问题，所以我必须检测字符串是否包含 '�' 字符才能修复 it.strpos work.Can 没有人对此说点什么吗？还有这个狗屎'?'字符是什么，如果有人能解释一下我会很高兴...

编辑：这是我的代码片段；

$name = $ldapHandler->get_user_info('username')['name'];
echo $name;
echo utf8_decode($name);
echo mb_convert_encoding($name,'utf-8');
echo utf8char(mb_convert_encoding($name,'utf-8'));

此代码的输出；

Bilgi ��lem Daire Ba�kanl���
Bilgi ?lem Daire Ba?kanl??
Bilgi Ýþlem Daire Baþkanlýðý
Bilgi İşlem Daire Başkanlığı (this is the correct string)

Answer 1

在将其存储到数据库中时使用 utf8_encode()。并在获取时使用 utf8_decode().

Answer 2

已经很久了，但我决定分享我遇到同样问题的解决方案。

这个功能对我有用：

function repair($value) {

    $res = @iconv("UTF-8", "UTF-8//IGNORE", $value);

    if (strlen($value) != strlen($res)) {
        return w1250_to_utf8($value);
    }

    return $res;
}

function w1250_to_utf8($text) {
    // map based on:
    // http://konfiguracja.c0.pl/iso02vscp1250en.html
    // http://konfiguracja.c0.pl/webpl/index_en.html#examp
    // http://www.htmlentities.com/html/entities/
    $map = array(
        chr(0x8A) => chr(0xA9),
        chr(0x8C) => chr(0xA6),
        chr(0x8D) => chr(0xAB),
        chr(0x8E) => chr(0xAE),
        chr(0x8F) => chr(0xAC),
        chr(0x9C) => chr(0xB6),
        chr(0x9D) => chr(0xBB),
        chr(0xA1) => chr(0xB7),
        chr(0xA5) => chr(0xA1),
        chr(0xBC) => chr(0xA5),
        chr(0x9F) => chr(0xBC),
        chr(0xB9) => chr(0xB1),
        chr(0x9A) => chr(0xB9),
        chr(0xBE) => chr(0xB5),
        chr(0x9E) => chr(0xBE),
        chr(0x80) => '&euro;',
        chr(0x82) => '&sbquo;',
        chr(0x84) => '&bdquo;',
        chr(0x85) => '&hellip;',
        chr(0x86) => '&dagger;',
        chr(0x87) => '&Dagger;',
        chr(0x89) => '&permil;',
        chr(0x8B) => '&lsaquo;',
        chr(0x91) => '&lsquo;',
        chr(0x92) => '&rsquo;',
        chr(0x93) => '&ldquo;',
        chr(0x94) => '&rdquo;',
        chr(0x95) => '&bull;',
        chr(0x96) => '&ndash;',
        chr(0x97) => '&mdash;',
        chr(0x99) => '&trade;',
        chr(0x9B) => '&rsquo;',
        chr(0xA6) => '&brvbar;',
        chr(0xA9) => '&copy;',
        chr(0xAB) => '&laquo;',
        chr(0xAE) => '&reg;',
        chr(0xB1) => '&plusmn;',
        chr(0xB5) => '&micro;',
        chr(0xB6) => '&para;',
        chr(0xB7) => '&middot;',
        chr(0xBB) => '&raquo;',
    );

    $search = array('Ý', 'ý', 'þ', 'Þ', 'ð', 'Ð');
    $replace = array('İ', 'ı', 'ş', 'Ş', 'ğ', 'Ğ');

    mb_internal_encoding("ISO-8859-1");
    return str_replace($search, $replace, html_entity_decode(mb_convert_encoding(strtr($text, $map), 'UTF-8'), ENT_QUOTES, 'UTF-8'));
}
