PHP AJAX，我希望比它更快

我正在制作Ajax登录表单，用于2d安全性（移动/邮件），这个脚本比我制作的速度慢得多。 2秒后，它会在手机上和fsocietif上发出回声1，如果有人想靠近我，我需要比它更快的速度。 有关更多文本

session_start();
include('admin/phppath/d.php');

if($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest') {
    if(@isset($_SERVER['HTTP_REFERER']))
    {
        if($_POST['token'] == $_SESSION['token2']) {
            $email = $_POST['email'];
            $password = $_POST['password'];
            $q = "SELECT * FROM `signup9501` WHERE email = '$email'";
            $r = mysqli_query($c,$q);
            $row = mysqli_fetch_array($r);
            $securityF = $row['securityF'];
            $onoff = $row['onoff'];

            if($onoff == 'mobile' && $securityF == 'on'){
                echo 1;
            }else if($onoff == 'email' && $securityF == 'on'){
                echo 1;
            }

            $rowpassword = $row['password'];
            $blocked = $row['blocked'];

            if (password_verify("$password", $rowpassword) && $blocked != '1') {
                $usrid = $row['id'];
                $usernum = $row['phone'];

                if($onoff == 'off' && $securityF == 'off' || $onoff == 'on' && $securityF == 'on'){
                    $_SESSION['email'] = $email;
                    echo 3;
                }else if($onoff == 'email' && $securityF == 'on'){

实际上，在发送电子邮件或消息时使用的不是脚本。标题位置在

ajax

中不起作用。返回

false

并在jsp中处理它谢谢，所以我现在不能让它更快吗？
