最近要做一个网页，具体内容是：上边有一个标题，下边分成两块，左边是地图。并且地图上有两个点，点击两个点有相应的提示信息，显示数据库里最新的两条数据信息。右边是一些文字说明。本人刚开始学习，做的也不是很好
<!DOCTYPE html>
<?php
/*
创建与数据库的连接
*/
$conn=mysql_connect("","","") or die("can not connect to server");
mysql_select_db("hdm0410292_db",$conn);
mysql_query("set names utf8");
//选择出两辆车插入的最新数据,并将两条语句存在数组里
$sql0="select * from car_info where carID='20140508'order by id desc limit 1";
$sql1="select * from car_info where carID= '20140510' order by id desc limit 1";
$sql=array($sql0,$sql1);
?>
