如何正确处理PHP Ajax乱码_PHP教程

由于XMLHTTP采用的是Unicode编码上传数据，而一般页面采用的是gb2312,这就造成显示页面时产生乱码。而当在获取页面时的XMLHttp返回的是utf-8编码，这就造成了显示产生乱码。

PHP Ajax乱码解决方法之一就是在PHP文件中显示声明为GB2312

header("Content-Type:text/html;charset=GB2312");

而对于发送到服务器的中文进行转码。

如下

$_POST["content"]=iconv("UTF-8","gb2312",$_POST["content"]);

因而这样可以解决PHP Ajax乱码问题

方法二，是都采用UTF-8编码。这里就不多说了
