Question

我有一个简单的程序卡片游戏我一直在制作，除了我的乐谱以外，一切似乎都很好。

我可以让分数自我调整并增加1但是当玩家连续获得2个正确答案时，分数仍为1。

        $Score=0;
        $PlayerCard = rand (0,51);
        $Cardrand = rand (0,51);
    }
    echo $Score;
?>

我已经尝试了$ variable ++ ++ $ Variable，我一直在尝试不同的方法，但仍然无法让计数器增加1以上。

请帮忙......

Answer 1

每次刷新页面时，您都会将$ score重置为0。

这就是为什么$ score ++只加1。

代码从上到下阅读。最先发生的事情之一是什么？ - 你将$ score设置为0.然后你在$ score ++中加入1得分;

实现此目的的唯一方法是在会话（推荐）或cookie或文件中设置得分变量，或者即使刷新页面也要保留变量值。

这是一个简单的例子：

session_start();

if(!isset($_SESSION['score'])){
    $_SESSION['score'] = 0;
}

if (isset($_GET['Higher'])) {
    if ($PlayerCard > $Cardrand) {
        $_SESSION['score']++;
    }
}

Answer 2

如果我认为你的游戏正确应该是这样的事情

    <form action="/testphp" method="get">
    <button name="Higher" type="submit" value="submit">Higher</button>
     <button name="Lower" type="submit" value="submit">Lower</button>
    <button name="NewDeal" type="submit" value="submit">NewDeal?</button>
    </form>
    </body>
