Question

如何在这个游戏中使用循环？这场比赛有10轮。当一名玩家获胜时，他将获得+1，直到它达到10轮，即游戏结束时。当用户正确输入2个字符但错误拼写时，我也可以问一下使用了什么函数？例如，ROcc而不是摇滚。它会接受用户输入吗？

Answer 1

下次，请考虑发布一些代码，告诉我们您至少尝试解决此问题。

在这种情况下，您可以创建一个包含以下顺序的数组：Rock＆gt;剪刀＆gt;纸。

$orderArray = array("rock", "scissors", "paper");

现在，对于每个玩家，我们必须遍历数组：

$player1Answer = 0;
$player2Answer = 0;
for ($i = 0; $i < count($orderArray); $i++) {
    if ($player1 == $orderArray[i])
       $player1Answer = i;
    if ($player2 == $orderArray[i])
       $player2Answer = i;
}

由于我们只有3个元素，因此不会对优化造成任何问题。现在我们必须检查获胜条件。这只是一种方法，我相信还有更好的方法。但它会做：

if ($player1Answer == $player2Answer)
    // DRAW
else if ($player1Answer == $player2Answer + 1 || ($player1Answer == 2 && $player2Answer == 0)
    // 1 wins
else
    // 2 wins

现在，对于您的第二个问题，请在下一次将其发布在单独的问题中，或者在网站上查看，它已被回答：

startsWith() and endsWith() functions in PHP

代码尚未在实时服务器上进行测试，因此可能会出现一些较小的错误（大写和其他内容）。
