浅析PHP中的UNICODE编码与解码_PHP教程

方法一:
代码如下:
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).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT);
}
else
{
$str .= $c2;
}
}
return $str;
}
//将UNICODE编码后的内容进行解码
function unicode_decode($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;
}

方法二:
代码如下:
　　function unicode2utf8($str){
　　　　if(!$str) return $str;
　　　　$decode = json_decode($str);
　　　　if($decode) return $decode;
　　　　$str = '["' . $str . '"]';
　　　　$decode = json_decode($str);
　　　　if(count($decode) == 1){
　　　　　　return $decode[0];
　　　　}
　　　　　　return $str;
　　　　}
