\u767b\u5f55\u540d\u6216\u5bc6\u7801\u9519\u8bef 这是什么编码？

Question

以前在Java编程中接触过，现在是忘记一点都没有了，连名字都忘记了。哪位大虾知道请指点一二，在PHP中如何翻译成汉字或正常的文字。谢谢！

[code="java"]

function unicode_encode($name)
{

$name = iconv(’UTF-8′, ‘UCS-2′, $name);
$len = strlen($name);
$str = ”;
for ($i = 0; $i < $len – 1; $i = $i + 2)
{
$c = $name[$i];
$c2 = $name[$i + 1];
if (ord($c) > 0)
{ // 两个字节的文字
$str .= ‘\u’.base_convert(ord($c), 10, 16).base_convert(ord($c2), 10, 16);
}
else
{
$str .= $c2;
}
}
return $str;
}

// 将UNICODE编码后的内容进行解码，编码后的内容格式：YOKA\u738b （原始：YOKA王）
function unicode_decode($name)
{
// 转换编码，将Unicode编码转换成可以浏览的utf-8编码
$pattern = ‘/([\w]+)|(\\u([\w]{4}))/i’;
preg_match_all($pattern, $name, $matches);
if (!empty($matches))
{
$name = ”;
for ($j = 0; $j < count($matches[0]); $j++)
{
$str = $matches[0][$j];
if (strpos($str, ‘\u’) === 0)
{
$code = base_convert(substr($str, 2, 2), 16, 10);
$code2 = base_convert(substr($str, 4), 16, 10);
$c = chr($code).chr($code2);
$c = iconv(’UCS-2′, ‘UTF-8′, $c);
$name .= $c;
}
else
{
$name .= $str;
}
}
}
return $name;
}

测试用例：

echo ‘

YOKA\u738b -> ‘.unicode_decode(’YOKA\u738b’).’

’;
$name = ‘YOKA王’;
echo ‘

’.unicode_encode($name).’

’;
