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

 World Cup Quiz




";

//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 ''."$theQuestion".'
';
   ?> 
 
   
  $theAnswer2"; ?>  
   $theAnswer3"; ?>  
   $theAnswer4"; ?>  
   

   

希望你能帮忙

谢谢
