确定Dreamweaver和我的本地主机服务器一直说他们是错误但我不知道在哪里请帮忙？

这是一个php脚本，用于判断用户是否已经拥有一个帐户，然后如果他没有，则会将他注册到数据库中

<html>
<head>
<style type="text/css">
p {color:white;font-size:20px;}
.toppa {width: 100%;background-color:#2D2D2D;}
</style>

<?php
//Database Information

$dbhost = "localhost";
$dbname = "a8423624_grubber";
$dbuser = "root";
$dbpass = "";

//Connect to database

mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error());
mysql_select_db($dbname) or die(mysql_error());

$username = $_POST['username'];  
$email = $_POST['email'];    
$password = md5($_POST['password']);
$repassword = md5($_POST['repassword']);

$month = $_POST['month'];  
$day = $_POST['day'];
$year = $_POST['year'];  

$Intro = 1;
$admin = "no";

首先，您应该启用error_reporting。其次，您应该使用mysql_real_escape_string来清理您的输入（否则有害的人可以SQL inject），第三，您应该在SQL查询后使用or die (mysql_error());，如下所示：

$checkuser = mysql_query("SELECT username FROM users WHERE username='$username'") or die(mysql_error());  
$checkuser1 = mysql_query("SELECT email FROM users WHERE email='$email'") or die(mysql_error());

如果您的SQL查询失败，您将看到正确的错误。

php错误但它在哪里？
