我有一个PHP代码,必须从mysql表中选择所有字段三个字段,但问题,结果只是2个字段如何修复此错误？

mysql表"用户"

的Fileds:

• ID.
• 用户.
• 密码.
• 日期.

结果是:

{"userlist":[{"id":"2","user":"user2"},{"id":"3","user":"michel"},{"id":"4","user":"georges"},{"id":"5","user":"testtest1"}],"success":1}

这是代码

<?php

/*
 * Following code will list all the emp
 */

// array for JSON response
$response = array();


    // include db connect class
    require_once __DIR__ . '/db_connect.php';

    // connecting to db
    $db = new DB_CONNECT();

// get all emp from emp table
$result = mysql_query("SELECT *FROM users") or die(mysql_error());

// check for empty result
if (mysql_num_rows($result) > 0) {


    // looping through all results
    // emp node …
