我正在创建一个网站，我已经在 XAMPP 上测试了几个星期，它一直在工作。但是自从我购买了域名和主机之后，将所有内容都放入了文件管理器（godaddy 主机）。当我将 .php 文件放在上下文中时，突然之间，带有 .php 的文件无法读取 php 代码。或者至少它确实读到了第一行，但之后的所有内容（甚至是 html 代码）在 php 标记之外都为空，并且页面显示为空白。我不知道为什么会出现这种情况，我已经搞砸了一段时间了，似乎无法弄清楚！有人想拍吗？非常感激！
<?php
session_start();
include($_SERVER["DOCUMENT_ROOT"].'/admin/classes/classes.php');
$log= new log($_SERVER["PHP_SELF"]);
if($_GET['logout']=='1'){
$sess = new SessionData();
$sess->Logout();
}
if($_SERVER['REQUEST_METHOD'] == "POST"){
$auth = new Authenticate();
extract($_POST);
if($auth->login($email,$pass)){
header('Location: index.php');
}else{
$error="<p class='red'>Invalid email or password.</p>";
}
}
?>
