Answer 1

<?php
include_once("connect.php");//连接数据库

$sql = "select * from quiz order by id asc";
$query = mysql_query($sql); //查询数据
while($row=mysql_fetch_array($query)){
$answers = explode('###',$row['answer']); //将答案选项分开
$arr[] = array(
'question' => $row['id'].'、'.$row['question'], //题目
'answers' => $answers //答案选项
);
}
$json = json_encode($arr); //转换json格式
?>
