PHP中对汉字进行unicode编码和解码的实现方法(必看)

实例如下：//将内容进行UNICODE编码functionunicode_encode($name){$name=iconv('UTF-8','UCS-2',$name);$len=strle

实例如下：

//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), 10, 16);
 }
 else
 {
 $str .= $c2;
 }
 }
 return $str;
}
$name = 'MY,你大爷的';
$unicode_name=unicode_encode($name);
echo '<h3>'.$unicode_name.'</h3>';
// 将UNICODE编码后的内容进行解码
function unicode_decode($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), 16, 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);
