PHP 中文 转UNICODE， JS 将UNICODE转为GBK

 首先是PHP下的中文转为UNICODE进行传递

function str_utf8_unicode($name){
$name = iconv('GBK','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($c2), 10, 16), 2, 0, STR_PAD_LEFT);
//$str .= base_convert(ord($c), 10, 16).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT);
} else {
$str .= '\u'.str_pad(base_convert(ord($c2), 10, 16), 4, 0, STR_PAD_LEFT);
//$str .= str_pad(base_convert(ord($c2), 10, 16), 4, 0, STR_PAD_LEFT);
}
}
//$str = strtoupper($str);//转换为大写
$str =strtolower($str);//转换为小写
return $str;
}
调用实例：$result[$i]['docsubject'] = str_utf8_unicode($result[$i]['docsubject']);

然后是JS下的补充函数
var GB2312UnicodeConverter = {
ToUnicode: function (str) {
return escape(str).toLocaleLowerCase().replace(/%u/gi, '\\u');
}
, ToGB2312: function (str) {
return unescape(str.replace(/\\u/gi, '%u'));
}
};

然后在转码调用
var zurl = "";
zurl = "read_id.php?id=" + zid;
//alert("zurl is:"+zurl);

$.getJSON(zurl,function(data){
var $jsontip = $("#jsonTip");
var strHtml = "";//存储数据的变量
$jsontip.empty();//清空内容
$.each(data,function(infoIndex,info){
strHtml += "ID："+info["id"]+"<br>";
// strHtml += "标题："+info["docsubject"]+"<br>";
strHtml += "标题："+GB2312UnicodeConverter.ToGB2312(info["docsubject"])+"<br>";
