增量在php while循环中

嗨,大家好,我想知道你是否可以帮助我在我的while循环中递增.我正在使用php编写在线测验,并希望每次选择提交按钮时更新qustion编号,但变量$ questionNumber只保留在一个

我的代码如下所示

<?php session_start(); ?>
<html>
<head>
<title> World Cup Quiz  </title>
</head>
<body>
<div align = center><strong> World Cup Quiz</strong></div>
<br />

<div align =center>
<?php



include ("dbConnect.php");

$_SESSION['number']=1;
$questionNumber = $_SESSION['number'];
$userScore=0;
$number= rand(1,4);

//search database for generated number and match ID
$dbQuery= "SELECT * FROM `questions 1.0` WHERE  `ID` =$number";
$dbResult=mysql_query($dbQuery);

echo "Question:".$questionNumber."/5<br>";

//Assign variables to each attribute

while ($dbRow=mysql_fetch_array($dbResult))

{


   $theID=$dbRow["ID"];
   $theQuestion=$dbRow["Question"];
   $theAnswer1=$dbRow["Correct Answer"];
   $theAnswer2=$dbRow["Wrong Answer 1"];
   $theAnswer3=$dbRow["Wrong Answer 2"];
   $theAnswer4=$dbRow["Wrong Answer 3"];
   $_SESSION['number']=$questionNumber+1;
}




  //Print Questions and Answers


    echo '<strong>'."$theQuestion".'</strong><br>';
   ?> <form name="correctAnswer" form method="post" action="quiz.php"> 
  <?php
   echo "$theAnswer1";?> <input type="radio" name="correctAnswer">
  <?php
   echo "<br>$theAnswer2"; ?> <input type="radio" name="wrongAnswer1"> 
   <?php
   echo "<br>$theAnswer3"; ?> <input type="radio" name="wrongAnswer2"> 
   <?php
   echo "<br>$theAnswer4"; ?> <input type="radio" name="wrongAnswer3"> 
   <br><input type="submit" value="Submit Answer">
   </form>


</div>
</body>

您正在重置脚本开头的数字:

$_SESSION['number']=1;

您需要将其更改为:

if (!isset($_SESSION['number']))
{
    $_SESSION['number']=1;
}
