复制代码 代码如下:

<?php
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;
}
