php接收ajax post数据编码只能是gb2312
各位大侠,我是一名初学者,用ajax post方式做的登录模块,提交数据到php,发现用gb2312编码能正常接收数据,用utf-8编码php端就没有反应。我的各个网页均已经设为utf-8编码了,为什么会这样?还有用gb2312发送后,服务器端能正常查询数据库,但是返回数据‘1’后,在js代码里面if与‘1’比较却不相等,结果进入else代码,是否也是编码格式不相同的问题?烦请各位大侠帮忙指点迷津,谢谢!
js代码如下:function loginphp(){
xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { msg = xmlhttp.responseText; if(msg == '1'){ document.getElementById("login").innerHTML="登录成功!"; }else if(msg=='2'){ document.getElementById("login").innerHTML="用户名或密码错误!"; }else{ document.getElementById("login").innerHTML=msg; }}
}
xmlhttp.open("POST","application/reglog/login.php",true);
//xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");
xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=gb2312");
xmlhttp.send("email="+$('email').value+"&pwd="+$('pwd').value);
}
php代码如下:
include_once "dbconn.php";
$sql = "select * from Basicinfo_user where user_email='".$_POST['email']."' and user_password='".$_POST['pwd']."'";
$num = $conne->getRowsNum($sql);
$conne->close_conn();
if($num == 1){
echo '1';
}else if($num == 0){
echo '2';
}else{
echo $conne->msg_error();
}
