Question

我在php中制作游戏。我的问题是如何将其循环到10轮，以及如何使这个不区分大小写，并接受前2个字母单词，即使它被拼错了。需要将用户输入到字符串。我设法编码，不知道接下来该做什么。

<html>
    <body>
    <h1>ROCK PAPER SCISSORS</h1>

    <?php

    print ('<form action="" method="post">');
    print ('<p>Player 1: <input type="text" name="p1" /></p>');
    print ('<p>Player 2: <input type="text" name="p2" /></p>');
    print ('<input type="submit" name="submit" value="PLAY" />');
    print ('</form>');

    if (isset($_POST['submit'])) {

        $player1score = 0;
        $player2score = 0;
        $draw = 0;
        $player1 = $_POST['p1'];
        $player2 = $_POST['p2'];

        if ($player1 == 'Scissors' && $player2 == 'Scissors') { 
            $draw++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif ($player1 == 'Rock' && $player2 == 'Rock') {
            $draw++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif ($player1 == 'Paper' && $player2 == 'Paper') {
            $draw++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif ($player1 == strcasecmp('Rock','ROCK') && $player2 == strcasecmp('Scissors','SCISSORS')){
            $player1score++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif($player1 == 'Rock' && $player2 =='Paper'){
            $player2score++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif ($player1 == 'Scissors' && $player2 == 'Rock') {
            $player2score++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif ($player1 =='Scissors' && $player2 =='Paper') {
            $player1score++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif ($player1 =='Paper' && $player2 =='Rock') {
            $player1score++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        } elseif ($player1 =='Paper' && $player2 == 'Scissors') {
            $player2score++;
            print "Player 1: $player1score<br>";
            print "Player 2: $player2score<br>";
            print "DRAW: $draw";
        }
    }

    ?>

如果对用户智商有疑问，请尽可能使用下拉框，收音机等限制选择预先定义的答案。

快速写了这个。如果有任何错误，我认为你将能够调试，但我认为你会得到这个... ...

<?php
session_start();
if(isset($_POST['play']))
{
    $p1 = $_POST['p1']; //don't need to check if post empty, 'cause used has a default value
    $p2 = $_POST['p2']; //don't need to check if post empty, 'cause used has a default value
    $loop = intval($_POST['play']);
    echo $p2;
    switch($p1)
    {
        case 'ROCK':
            if($p2=='PAPER')$_SESSION['game'][$loop]='Round '. $loop . ' - Player 2 WINS!';
            else if($p2=='SCISSORS')$_SESSION['game'][$loop]='Round '. $loop . ' - Player 1 WINS!';
            else if($p2=='ROCK')$_SESSION['game'][$loop]='Round '. $loop . ' - It\'s a DRAW!';
            break;
        case 'PAPER':
            if($p2=='ROCK')$_SESSION['game'][$loop]='Round '. $loop . ' - Player 2 WINS!';
            else if($p2=='SCISSORS')$_SESSION['game'][$loop]='Round '. $loop . ' - Player 1 WINS!';
            else if($p2=='PAPER')$_SESSION['game'][$loop]='Round '. $loop . ' - It\'s a DRAW!';
            break;
        case 'SCISSORS':
            if($p2=='PAPER')$_SESSION['game'][$loop]='Round '. $loop . ' - Player 1 WINS!';
            else if($p2=='ROCK')$_SESSION['game'][$loop]='Round '. $loop . ' - Player 2 WINS!';
            else if($p2=='SCISSORS')$_SESSION['game'][$loop]='Round '. $loop . ' - It\'s a DRAW!';
            break;

    }

    $loop++;
}
?>
<html>
<body>
<h1>ROCK PAPER SCISSORS</h1>
<form method="post">
<input type="hidden" name="play" value='<?php if(isset($loop))echo $loop; else echo 1; ?>'>
<p>Player 1: 
    Rock<input type="radio" name="p1" value='ROCK' checked>
    PAPER<input type="radio" name="p1" value='PAPER'>
    SCISSORS<input type="radio" name="p1" value='SCISSORS'>

<p>Player 2:

   SCISSORS<input type="radio" name="p2" value='SCISSORS'>
</p>
<button>Submit</button>
</form>
<?php
    if(!empty($_SESSION['game']))
    {
    $game=$_SESSION['game'];
    foreach($game as $count=>$comment)echo $comment.'<br>';
    if($count==10)echo '<h1>END OF GAME</h1>';
    }
?>
</body>

为了使其不区分大小写，请在输入上使用strtolower使其为小写，并使用小写字符串进行比较。在代码中替换它：

$player1 = $_POST['p1'];
$player2 = $_POST['p2'];

有了这个：

$player1 = strtolower($_POST['p1']);
$player2 = strtolower($_POST['p2']);

您还可以通过使用多个表达式来减少elseif块的数量之一。

两个

elseif($player1 == 'Rock' && $player2 =='Paper')

和

elseif ($player1 == 'Scissors' && $player2 == 'Rock')

导致相同的操作。您可以将两者组合成一个具有OR表达式的块，如下所示：

if(($player1 == 'Rock' && $player2 =='Paper') || ($player1 == 'Scissors' && $player2 == 'Rock'))

要循环10次，你可以像这样使用for循环：

for($round=1; $round<=10; $round++)

我建议你看看http://www.w3schools.com/php/default.asp，他们有很好的PHP指南和示例。

编辑：bluepinto使用switch获得了更好的结构解决方案。
