php开发留言板之数据库文件配置(二)

新建文件conn.php 用来设置连接数据库文件

<?php
header('content-type:text/html;charset=utf8');
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "bbs";
 
$conn = mysqli_connect($servername,$username,$password,$dbname);
if(!$conn) {
	die("连接失败:".mysqli_connect_error());
}

mysqli_query($conn,"set names utf8");//使用utf-8中文编码
?>
