Question

我正在尝试构建一个简单的Rock，Paper，Scissors游戏。我正在使用XAMPP堆栈。我已成功检索到用户选择的岩石，纸张或剪刀，并将其插入表格中。我也成功地从对手那里选择了一个随机的选择＆＃34;通过使用array_rand但我不能同时将此变量/整数插入表中。我曾经有能力插入对手的选择＆＃34;但从来没有与用户选择，它总是一个或另一个。并且，我认为我会将两个选项转换为整数，然后使用if / else语句来确定每个游戏的赢家，但是在我对此进行测试时，它似乎并不总能产生正确的答案。我认为可能有一些不必要的代码，例如我在那里的var_dump，所以我可以看到我已经成功地将选项转换为整数，以便我可以比较选择以便在逻辑上确定胜利者，例如。谢谢你的帮助。

以下代码将您的发布内容修复为数据库。它不能解决WIN / LOSE / DRAW可能性的问题。您还应该知道，您的代码会为playermove和text（rock，paper，scissors）发布一个整数，供对手移动。您有两个Insert语句将导致每个游戏创建2个单独的行。

$pmove   = $_POST['playermove'];

$yourvar = intval($pmove);
echo "You chose: " . $yourvar . "<br>";
echo "<br>";

$oppdecision = array('rock', 'paper', 'scissors');
$oppresult = array_rand($oppdecision, 1);
echo "Your opponent chose: " . $oppresult . "<br>";
$oppsmove = $oppdecision[$oppresult];
echo $oppsmove . "<br>";

$oppvar = intval($oppresult);


$sql   = "INSERT into tb_rps2 (oppmove,playermove) VALUES ('$oppresult','$pmove')";
$success = $conn->query($sql); 

 if ($yourvar = 1 & $oppvar = 0) {
    echo '<br>' . "you tie";
} elseif ($yourvar = 1 & $oppvar = 1) {
    echo '<br>' . "you lose";
}  elseif ($yourvar = 1 & $oppvar = 2) {
     echo '<br>' . "you win";
}  else {
    echo '<br>' . "Good game!";
} 

$conn->close();
