- php部分
<?php

$conn = mysql_connect($mysql_server_name,$mysql_username,$mysql_password) or die('error connecting');
mysql_query('set names utf8');
mysql_select_db($mysql_database);
$result = mysql_query('select * from study');
$data = '';
$array = [];
class User{
public $name;

}
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$user = new User();
$user->name = $row['name'];
$user->age = $row['age'];
$array[] = $user;
}
$data = json_encode($array);
echo $data;
