PHP中UNICODE 编码和解码方法

方法一:
<?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 

<p>方法二:</p>

<pre class="html " data-pbcklang="html" data-pbcktabsize="4">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;
}
