1.配置文件：connect.php
<?php $host="localhost"; $db_user="root"; $db_pass="root"; $db_name="wh"; $timezone="Asia/Shanghai"; $link=mysql_connect($host,$db_user,$db_pass); mysql_select_db($db_name,$link); mysql_query("SET names UTF8"); header("Content-Type: text/html; charset=utf-8"); ?>
2.页面：index.php
<!DOCTYPE HTML>
