Question

我为摇滚纸剪刀游戏做了一个小代码，它对我来说非常好。但是我需要计算最后一页的胜利，损失和数字。

我是php的新手，我无法这样做。

的index.php

<html>
<head>
     <title>Rock Paper Scissors Game</title>
</head>
<body>
<h1> Rock Paper Scissors Game</h1>
<form action="submit.php" method="POST">
    <p>Please Choose Your Player</p>
    <h2>Rock<input type="radio" value="rock" name="playerturn"  /><br />
       Paper<input type="radio" value="paper" name="playerturn"  /><br />
       Scissors<input type="radio" value="scissors" name="playerturn" /><br />
    </h2>
    <p><input type="submit" value="Play"></p>
</form>
</body>
</html>

Submit.php（最终页面）

<html>
<head>
</head>
<body>
<h1> Rock Paper Scissors Game</h1>
<?php
    if($_POST['playerturn']){

}

    else if(!$_POST['playerturn']){

}
        $playerturn = $_POST['playerturn'];
        $rpc= array('rock', 'paper', 'scissors');
        $rndm= rand(0,2);
        $Computer=$rpc[$rndm];

    echo '<h2>You picked: '.$playerturn.'</h2>';
    echo '<br /><br />';
    echo '<h2>The computer picked: '. $Computer .'</h2>';
  echo '<br /><br />';
    if($playerturn == $Computer){
    }
    if ($playerturn == $Computer){
    echo ' Draw  ';
    }
    else if($playerturn == 'rock ' && $Computer == 'scissors'){
    echo '<h1>You Win!</h1>';
}
    else if($playerturn == 'rock' && $Computer == 'paper'){
    echo  '<h1>You Lose! </h1>';
}
    else if($playerturn == 'scissors' && $Computer == 'rock'){
    echo  ' <h1>You Lose!</h1> ';
}
    else if($playerturn == 'scissors' && $Computer == 'paper'){
    echo '<h1> You Win! </h1>';
}
    else if($playerturn == 'paper' && $Computer == 'rock'){
    echo '<h1>You Win!</h1>';
}
    else if($playerturn == 'paper' && $Computer == 'scissors'){
    echo '<h1>You Lose!</h1>' ;
}

我们是否需要创建一个数据库然后才能运行。或者我们可以使用session来做同样的事情。

Answer 1

要在PHP中使用会话，您需要

session_start();

位于PHP文件的顶部。

然后，您可以使用$ _SESSION作为关联数组，例如

$_SESSION['my_wins'] = 99;
$_SESSION['cpu_wins'] = 8;

Answer 2

我正在为您的游戏提供工作代码：

gameStart.php

<?php
session_start();

if(isset($_GET['exit']) == 1){
session_destroy();
header('Location: gameStart.php');
}
?>
<html>
<head>
     <title>Rock Paper Scissors Game</title>
</head>
<body>
<h1> Rock Paper Scissors Game</h1>
<form action="gameResult.php" method="POST">
    <p>Please Choose Your Player</p>
    <h2>Rock<input type="radio" value="rock" name="playerturn"  /><br />
       Paper<input type="radio" value="paper" name="playerturn"  /><br />
       Scissors<input type="radio" value="scissors" name="playerturn" /><br />
    </h2>
    <p><input type="submit" value="Play"></p>
</form>
</body>

gameResult.php

<?php
// Start the session
session_start();

if(empty($_SESSION['your_win'])  &&

    $_SESSION['your_win'] = 0;
    $_SESSION['cpu_win'] = 0;
    $_SESSION['draw'] = 0;
    //Printing the initiation of session variables for your reference
    echo $_SESSION['your_win']; 
    echo $_SESSION['cpu_win'];
    echo $_SESSION['draw'] ;
}
    $playerturn = $_POST['playerturn'];
    $rpc= array('rock', 'paper', 'scissors');
    $rndm= rand(0,2);
    $Computer=$rpc[$rndm];

    echo '<h2>You picked: '.$playerturn.'</h2>';

    echo '<h2>The computer picked: '. $Computer .'</h2>';

    if ($playerturn == $Computer){
        $_SESSION['draw']+=1;

请单击“退出”选项以正确销毁会话。希望这会对你有所帮助!!!。
