php로 mysql 테이블작성하는데 구문좀 봐주세요ㅠㅠ

<?php
header("Content-Type: text/html; charset=UTF-8");
include_once('./_common.php');

 $db_host = "localhost"; 
 $db_user = "xxxxx"; 
 $db_passwd = "xxxxxxxx";
 $db_name = "gnu5"; 
 $connect = mysql_connect($db_host,$db_user,$db_passwd);

mysql_select_db($db_name,$connect);

$sql = "create table `guest` (
       `id` varchar(12) not null,
       `name` char(10) not null,
       `sex` char(4),
       `age` int,
       `point` int,
       `email` varchar(30),
       primary key(id) ); ";

$result = mysql_query($sql, $connect);

if($result){ echo " 테이블 생성 성공"; }
else{ echo "실패";exit;}

?>
