Question

我想回显从json对象中从数据库中提取的php字符串。请问是否可以，如果是的话，我在哪里弄错了？以下是代码：其余的效果很好。

<script type='text/javascript'>

(function() {
   <?php
     $sql = "SELECT * FROM quiz WHERE subject='SOCIAL STUDIES' AND type='challenge'";
     $results = $pdo->query($sql);
     $results->setFetchMode(PDO::FETCH_ASSOC);
     while($rows = $results->fetch()){
     ?>

    var questions = [{
        question: "<?php echo $rows['text'];?>",
        choices: [2, 5, 10, 15, 20],
        correctAnswer: 2
        }, 
  <?php 
    }
  ?>
    }];

您可以尝试

对于json格式，您应该使用json_encode

$sql = "SELECT * FROM quiz WHERE subject='SOCIAL STUDIES' AND type='challenge'";
$results = $pdo->query($sql);
$results->setFetchMode(PDO::FETCH_ASSOC);
while($rows = $results->fetch()){
    $q = $rows['text'];
    $result[] = array(
        "question" => $q,
        "choices" => [2, 5, 10, 15, 20],
        "correctAnswer" => 2
    ); 
}
$arrRecord['data']['success'] = $result;
echo json_encode($arrRecord);
