<?php
// 创建数据库连接
$con = mysql_connect("localhost",'root','') or die('error:'.mysql_error());
mysql_select_db('hyxx',$con) or die('error:'.mysql_error());
mysql_query('set NAMES utf8');
?>

userListt.php

  
    
<?php
require_once 'inc/dbConn.php';
//这是啥东东。。
date_default_timezone_set("PRC");
//读数据。。。
  $sql = "select * from user order by id asc";
  $result = mysql_query($sql,$con);
  $userList = '';
  while($rs = mysql_fetch_array($result)){
        $userList[] = $rs;
    }
          // 循环用户列表
        foreach ($userList as $user){
          echo "
