网站连接数据库，打开错误，是什么问题mysql_connect() in？

网站打开后显示错误如下：数据库连接后网站错误Fatal error: Uncaught Error: Call to undefined function mysql_connect() in D:\wwwroot\xxx.com\conn.php:3 Stack trace: #0 D:\wwwroot\xxx.com\nav.php(6): include_once() #1 D:\wwwroot\xxx.com\sysadmin.php(11): include_once('D:\\wwwroot\\xxx...') #2 {main} thrown in D:\wwwroot\xxx.com\conn.php on line 3这个是数据库用密码数据库名：syzb 用户名：syzb 密码：ckBf3S8TXpLPPMbi这个是CONN配置文件：<?phpheader("Content-type: text/html; charset=utf-8");$con = mysql_connect("localhost","syzb","ckBf3S8TXpLPPMbi");if (!$con) { die('Could not connect: ' . mysql_error()); }mysql_select_db("syzb", $con);mysql_query("set names utf8");?>求大神指点，看看那里错了。
