Question

我已经意识到有很多关于PRG，后请求获取模式的说法，但我找不到任何特定的PHP。假设我有包含表单的HTML文件，我在php脚本的末尾包含了HTML，如下所示：

<?php   include '../html/gozd.html';   ?>

现在我想修改我的php脚本，以便用户在刷新浏览器窗口时无法重新发布数据，并且他不能回到不同类型的表单输出等之间。基本上Web浏览器不应该记住任何除了表格显示和表格结果外，所有历史记录。

我的页面是一个关于战斗的简单游戏，当用户点击刷新时，它不需要按下“战斗”按钮就可以继续战斗，他甚至可以点击浏览器按钮而无需点击“Escape”表单按钮。我如何在我的代码中更正此问题？但请记住，我已经包含了HTML页面，并且HTML页面上显示的内容就是这样：

<?php 
if(!$_POST and $poskodbe != '0') { ?>

<p>You are attacked<?php text($spol); ?> by <?php text($monster); ?> !</p>

<form action='../php/gozd.php' method='post'>
<input type='submit' name='action' value='Fight' /> ali 
<input type='submit' name='action' value='Escape' />
<input type='hidden' name='monster' value= '<?php text($monster); ?>' />
</form>

<?php } 

else { ?>
more HTML tags here etc... <?php } ?>

HTML：

<body>
