以下实际上是我的 php 类的作业。我在我的本地主机上解决了这个问题。一切都在那里运行完美，但是当我将其上传到我的实时站点时，逻辑变得一团糟。这是典型的“猜谜游戏”程序。没有报告错误。
唯一的问题是，在实时服务器上，用户可以输入任何内容 ——甚至是“1”，这表明他们的输入“太高了”。
这可能是我网站的（fatcow）php 设置的问题吗？我认为正在发生的事情不知何故将我的会话变量显示为“零”，而不是 rand(1, 10) 数字。为什么会发生这种情况？如何修复它以使其与在本地主机上的工作方式相同？
编码：
<?php
session_start();
error_reporting (E_ALL | E_STRICT);

include('includes/header.inc.php');
if (isset($_POST['finish']))

unset($_SESSION);
$_SESSION = array();
session_destroy();
die ('<h2>Congratulations</h2>
<p>Your session has been reset.<br />
Click <a href="guessingGame.php">HERE</a> to play again!</p>');
}
elseif (isset($_POST['guess']))
{
$_SESSION['count'] = $_SESSION['count'] + 1;
$guess = $_POST['guess'];
if (!ctype_digit($guess) || $guess <= 0 || $guess > 10 )
{
echo'<p span class="italic">SORRY, that entry is invalid</span></p>';
}
