如何在关闭php中的弹出窗口后重定向到另一个页面，这对chrome和FF用户来说很好

我制作了一个用户使用谷歌登录的网站，在那里会打开一个弹出窗口进行登录，当用户单击提交按钮时，弹出窗口关闭&用户重定向到另一个页面。

我已经完成了代码，但它在FF bt中工作良好，而在chrome 中不工作

这是我的代码，有人能建议我需要做什么更改吗？这样它也能在chrome中工作。

 <?php
   @session_start();
   require 'openid.php';
   try {

$openid = new LightOpenID;
if(!$openid->mode) {
    if(isset($_GET['login'])) {
        $openid->identity = 'https://www.google.com/accounts/o8/id';
        $openid->required = array('namePerson/first', 'namePerson/last', 'contact/email');
       // @header('Location: ' . $openid->authUrl());
    echo "<script>location.href='".$openid->authUrl()."'</script>";
    }
} elseif($openid->mode == 'cancel') {
    echo 'User has canceled authentication!';
} else {
    if($openid->validate())
    {           
         'User <b>' . $openid->identity . '</b> has logged in.<br>';
         "<h3>User information</h3>";
        $_SESSION['identity'] = $openid->identity;
        $identity = $openid->identity;
        $attributes = $openid->getAttributes();
        $_SESSION['email'] = $attributes['contact/email'];
        $_SESSION['first_name'] = $attributes['namePerson/first'];
        $_SESSION['last_name'] = $attributes['namePerson/last'];

        /* "mode: " . $openid->mode . "<br>";
         "identity: " . $identity . "<br>";
         "email: " . $email . "<br>";
        "first_name: " . $first_name . "<br>";
         "last_name: " . $last_name . "<br>";*/

    }
    else
    {
        echo 'User ' . $openid->identity . 'has not logged in.';
    }

    echo "<script>window.close();</script>";
    echo '<script>window.opener.location.href="index2.php"</script>';

 }
    } catch(ErrorException $e) {
     echo $e->getMessage();
}
?>
