实例如下：
PHP;">
//将内容进行UNICODE编码
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),16);
}
else
{
$str .= $c2;
}
}
return $str;
}
$name = 'MY,你大爷的';
$unicode_name=unicode_encode($name);
echo '
'.$unicode_name.'
'; // 将UNICODE编码后的内容进行解码 function unicode_decode($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),10); $c = chr($code).chr($code2); $c = iconv('UCS-2','UTF-8',$c); $name .= $c; } else { $name .= $str; } } } return $name; } echo 'MY,\u4f60\u5927\u7237\u7684 -> '.unicode_decode($unicode_name);以上这篇PHP中对汉字进行unicode编码和解码的实现方法(必看)就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持编程之家。
