我需要一些帮助。大约十年前，我为网站联系表单编写了一个不错的 PHP 邮件脚本。显然，它已经过时了，现在在某些地方不起作用。我需要一些帮助来弄清楚为什么这个新的开始根本不起作用。它甚至没有显示基本页面，错误，什么也没有，只是一个白屏。现在所有内容都在这一页上，我将在接下来附上。请告诉我你看到了什么！谢谢！
<?php
$errors = [];
$errorMessage = '';
if (!empty($_POST)) {
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
if (empty($name)) {
$errors[] = 'Name is empty';
}
if (empty($email)) {
$errors[] = 'Email is empty';
} else if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$errors[] = 'Email is invalid';

这发生在一个免费托管平台（000webhost）上，该平台由于多种原因而臭名昭著。我猜他们声称他们全面强制执行 PHP v8，这就是破坏我原创的原因。不过有趣的是，我在 GoDaddy 的多个地方使用了原始的表单/脚本，它在那里仍然工作得很好...现在迁移到这个主机上的另一个免费主机（奖励空间），它使用户能够从 V5 等版本降级 php。我只需要让一些东西发挥作用...
