我已经开始为一个关于生物的游戏编写一个 PHP 脚本，有 4 个是/否问题，我想做的是编写一个函数，该函数将显示 2 个表示是和否的按钮，然后每次运行时给出不同的名称函数，例如 yes1 和 no1，那么下次运行该函数时，按钮的名称将是 yes2 和 no2。

我已经尝试过这样做，但它不能正常工作，下面是我到目前为止所做的代码，任何帮助将不胜感激。

<?php
session_set_cookie_params(2592000);
session_start();
?>

<html>
<head>
<title>Creature Guessing Game</title>
</head>
<body>
<h1>Creature Guessing Game</h1>
<p> Welcome to the creature guessing game! </p>
<p>Click the button below to start or restart the game </p>

<form method="post" action="Creatures.php">
<input type="submit" name="start" value="Start Game" />
</form>
 <?php
 $questions = array('Does the creature live on land?', 'Does it have wings?', 'Does it live near water?', 'Can it fly?');
 function repeat()
 {
 $number = 0;
 $number++;
 echo "<form method ='post' action='Creatures.php'>
<input type='submit' name='yes'.$number value='Yes' />
<input type='submit' name='no'.$number value='No' />
</form>";

 }
//If form not submitted, display form.
if (!isset($_POST['start'])){
?>
<?php
} //If form is submitted, process input
else{ 
switch($_POST)
{
case yes1:
echo $questions[0];
repeat();
break;
case no1:
echo $questions[1];
repeat();
break;
case yes2:
echo $questions[2];
repeat();
break;
case no2:
$questions[3];
repeat();
}
}
?>
</body>
</html>

为此，您需要维护请求之间的状态。

 function repeat() {
      $number = $_SESSION['number'];
      $number++;
      echo "<form method ='post' action='Creatures.php'>
     <input type='submit' name='answer' value='Yes' />
     <input type='submit' name='answer' value='No' />
     </form>";
     $_SESSION['number'] = $number;
 }

转变

   if($_POST['answer']=='Yes') {
      switch($_SESSION['number']) {
            case 1:
            break;
            case 2:
            break;
      }
   } else {
      switch($_SESSION['number']) {
            case 1:
            break;
            case 2:
            break;
      }
   }

我不同意接受的答案：这是一种无需会话即可进行的更简单方法：

function repeat() {
      static $number = 0;
      $number++;
      echo "<form method ='post' action='Creatures.php'>
     <input type='submit' name='answer' value='Yes' />
     <input type='submit' name='answer' value='No' />
     </form>";
 }

您必须将“数字”存储在会话或 cookie 中，因为每次提交（重新加载）页面时它都会丢失该值。
