我的脚本有问题，但我不确定它为什么会发生，可能是由于会话或 HTTP 标头。我希望我的登录脚本以这种方式“当用户登录时，应向管理员发送一封包含用户信息的电子邮件”，因此通过在以下代码中排除电子邮件部分，只需登录即可正常工作，我也在单独的文件中测试了电子邮件部分有效美好的。但我不明白为什么电子邮件没有发送并且页面显示为带有以下代码的白色空白屏幕。

session_start();
$errors = array();

if(isset($_POST['submit']) == "Login") {

    if(empty($_POST['username'])) { $errors[] = "Please enter Username! ";} 
    else { $username = mysql_real_escape_string($_POST['username']); }

    if(empty($_POST['password'])) { $errors[] = "Please enter Password! ";} 
    else { $password = mysql_real_escape_string($_POST['password']);}   

    if(empty($errors)) {
        $sql = mysql_query("SELECT * FROM users WHERE `username` = '".$username."' AND `password` = sha1('".$password."')");
         $row = mysql_fetch_assoc($sql);

        if($row) {  
            $_SESSION['user_login'] = true;
            $_SESSION['user_id'] = $row['user_id'];
            $_SESSION['full_name'] = $row['full_name'];

            /*******************Send Email***************************/
            //Send user information to admin            
            $to = "xxx@XXX.com";
            $from = "XXX@xxx.com";

            //Get User Information
            $Full_Name = $row['full_name'];
            $Browser = $_SERVER['HTTP_USER_AGENT'];          
            $User_IP = $_SERVER['REMOTE_ADDR'];
            // If IP address exists
            // Get country (and City) via  api.hostip.info
            if (!empty($User_IP)) {
                $country=file_get_contents('http://api.hostip.info/get_html.php?ip='.$User_IP);
                list ($_country) = explode ("\n", $country);
                $_country = str_replace("Country: ", "", $_country);
            }

基本调试。在发送电子邮件之前，添加

error_reporting(E_ALL);
ini_set('display_errors', 'on');

然后运行，解决问题，然后在排序后删除这两行。
