任何人都知道如何解决这个问题？

<?php
$auctionSurvey = "SELECT questions.question_id, answers.question_id, answers.survey_id, question_body, answer_body FROM questions
                  INNER JOIN answers ON answers.question_id = questions.question_id
                  WHERE answers.survey_id='1'";
$aucResult = mysql_query($auctionSurvey) or die (mysql_error());

while ($auctionRow = mysql_fetch_assoc($aucResult)) {
    echo $auctionRow['question_body'] . $auctionRow['answer_body'];
}

Answer 1

$questionId = 0;
while($auctionRow = mysql_fetch_assoc($aucResult)){
   if($auctionRow['question_id'] != $questionId){
        echo $auctionRow['question_body'];
        $questionId = $auctionRow['question_id'];
   }  
   echo $auctionRow['answer_body'];
}

添加一些HTML来格式化它，这应该适用于你。
