Question

所以，在尝试登录localhost中的html页面后，我在firebug中收到此错误。我正在尝试建立一个登录页面。使用php和extjs 3.2.1

这是第一行html行的错误

DOCTYPE HTML PUBLIC“ - // W3C // DTD HTML 4.01 // EN”“http://www.w3.org/TR/html4/strict.dtd”

我的php代码使用php5.3.10

 <?php

ob_start();
$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name="my_db"; // Database name 
$tbl_name="my_user"; // Table name 


mysql_connect("$host", "$Username", "$Password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

$Username=$_POST['Username']; 
$Password=$_POST['Password']; 

$Username = stripslashes($Username);
$Password = stripslashes($Password);
$Username = mysql_real_escape_string($Username);
$Password = mysql_real_escape_string($Password);
$sql="SELECT * FROM $tbl_name WHERE Username='$Username' and Password='$Password'";
$result=mysql_query($sql);

$count=mysql_num_rows($result);

if($count==1){

session_register("Username");
session_register("Password"); 
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
ob_end_flush();
?>

我想首先测试页面login_success.php页面。

<html>
<body>
Login Successful
</body>
</html>

html代码
