重要 前台和后台访问的时候，都是空白页

<?Php
$Host = "166.111.9.181";
$Database = "nsse";
$DbaUser     = "nsse";
$DbaPassword = "690201";
 
 
////数据库的连接
 
$db = mysql_pconnect($Host, $DbaUser,$DbaPassword);
if(!$db)
{
echo "Error: Could not connect to database.Please try again.";
        exit;
}
else
{
	echo " success" ;
 
$query = "SELECT name FROM jos_users where id = 63";
$result = mysql_query($query);
echo $result;
 
echo "1";
 
}
 
 
?>
