PHP中对汉字进行UNICODE编码和解码的功能

<?php //将内容进行UNICODE编码,编码后的内容格式:\u56fe\u7247 (原始:图片)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 $str;}// 将UNICODE编码后的内容进行解码,编码后的内容格式:\u56fe\u7247 (原始:图片)function unicode_decode($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; $j '.unicode_encode($name).'';//解码echo '<h3>'.unicode_decode('\u56fe\u7247').'</h3>';
