ajax对中文处理，你最好做一下转换，因为编码的问题造成的

因为你有 header('Content-Type:text/html;charset=gbk');
所以 ajax 会将返回的内容按 gbk 解释
但是 ajax 总是以 utf-8 向外发送数据的
因此你 $queryString = $_POST['queryString'];
得到的是 utf-8 编码的数据，当你 echo $sql; 时，就将 utf-8 的内容当做 gbk 发出了，所以出现乱码
为此你需要
$queryString = iconv('utf-8', 'gbk', $_POST['queryString']);
将 ajax 传来的数据转一下码
