Utf-8到UTF-16BE

Question

我在php中保存了一条记录“فحصالرسالةالعربية”，它总是保存为：

فحص الرسالة العربية

当我检索它时，我想把它转换成UTF-16BE字符，所以我使用了一个函数，它返回：

002600230031003600300031003b002600230031003500380031003b002600230031003500380039003b0020002600230031003500370035003b002600230031003600300034003b002600230031003500380035003b002600230031003500380037003b002600230031003500370035003b002600230031003600300034003b002600230031003500370037003b0020002600230031003500370035003b002600230031003600300034003b002600230031003500390033003b002600230031003500380035003b002600230031003500370036003b002600230031003600310030003b002600230031003500370037003b

这是m用来转换从数据库中检索的字符串的函数

function convertCharsn($string) {
    $in = '';
    $out = iconv('UTF-8', 'UTF-16BE', $string);
    for($i=0; $i<strlen($out); $i++) {
      $in .= sprintf("%02X", ord($out[$i]));
    }
    return $in;
}

但当我在下面的url中输入相同的字符时，它显示的字符与我的字符串不同。http://www.routesms.com/downloads/onlineunicode.asp

正在返回：

0641062D063500200627064406310633062706440629002006270644063906310628064A0629

我想我的字符串被转换，因为它是在上述网址转换。我的数据库排序规则是utf-8_general_ci

基本上，您需要首先从HTML实体中解码出这些字符。只需使用html_entity_decode()即可

$rawChars = html_entity_decode($string, ENT_QUOTES | ENT_HTML401, 'UTF-8');

convertCharsn($rawChars);

否则，您只是对实体进行编码。您可以看到，&在UTF16中是0026，而#是0023。因此，您可以在上面发布的代码转换中看到00260023的重复序列。所以先把它解码，然后你就可以...
