Javascript 如何在php中添加延迟

用户单击验证链接时的帐户验证过程。他/她立即重定向到仪表板。但我想给他/她的帐户已经验证了几秒钟的确认信息。 这是我的密码

                    <?PHP
require_once 'include/Functions.php';
$db = new DB_Functions();




if(isset($_GET['username'])&&isset($_GET['q']))
{  
 $username= $_GET['username'];  

$hash= $_GET['q'];  




 $salt = "498#2D83B631%3800EBD!801600D*7E3CC13";

         $resetkey = hash('sha512', $salt.$username);


        if($hash==$resetkey){

            $user = $db->activateAccount($username);

             if ($user != false) {
        // user is found
        echo '<script>';
    echo 'document.getElementById("result_status").innerHTML = "<strong>Congratulations!  Your Account has been verified .</strong>"';

    echo '</script>';


       $passwords=$db->getPasswordFromUsername($username);

    $users = $db->loginUserWithMdfPassword($username, $passwords);
     if ($users != false) {
        // password is found

       $properlyLogged=true;


if($properlyLogged) {
    // season for storing data start here

session_start();

$_SESSION['username']=$username;


header('Location: http://localhost/mywebsite/dashboard.php');

exit();
 // season for storing data end  here

    }}


}

        }else {
            echo '<script>';
      echo 'document.getElementById("result_status").innerHTML = "<strong>Session has been expired.</strong>"';

    echo '</script>';




}}



?>

使用JavaScript方法可能会更容易

而不是
标题（'位置：http://localhost/mywebsite/dashboard.php');

放

echo'设置超时（函数（）{window.location.href=”http://localhost/mywebsite/dashboard.php"}, 5 * 1000);'

这将等待X*1000毫秒（在我的示例中为5秒），然后重定向到目标。
sleep
无法满足您的需要。
您正在使用
标题（'location:…'）重定向您的用户并且在输出数据后不能修改标题信息（即，向用户显示消息）。
您必须使用带有
setTimeout

<?PHP
 require_once 'include/Functions.php';
 $db = new DB_Functions();
 if(isset($_GET['username'])&&isset($_GET['q']))
 {  
   $username= $_GET['username'];  
   $hash= $_GET['q'];  
   $salt = "498#2D83B631%3800EBD!801600D*7E3CC13";
   $resetkey = hash('sha512', $salt.$username);
   if($hash==$resetkey){
        $user = $db->activateAccount($username);
         if ($user != false) {
    // user is found
    echo '<script>';
    echo 'document.getElementById("result_status").innerHTML = "<strong>Congratulations!  Your Account has been verified .</strong>";';
// set timeout for 3 seconds - then redirect
    echo "setTimout(function(){window.location.href = 'http://localhost/mywebsite/dashboard.php';},3000)"
echo '</script>';

   $passwords=$db->getPasswordFromUsername($username);

$users = $db->loginUserWithMdfPassword($username, $passwords);
 if ($users != false) {
    // password is found

   $properlyLogged=true;


   if($properlyLogged) {
       // season for storing data start here
       session_start();
       $_SESSION['username']=$username;
       //comment out header redirect
       //header('Location: http://localhost/mywebsite/dashboard.php');
       exit();
      // season for storing data end  here
}}

使用Sleep函数：如何在代码中使用它？你能告诉我吗？
