PHP Redirect on Database Connection Error

I'm new to PHP - after doing a lot of ASP and I'm stumbling on a few issues.
The first issue I have is redirecting to a new page during error handling.

I have the following code:

<?php
session_start();
$error_text = $_SESSION['dberror'];
include 'inc/dbconnect.php';
include 'inc/session_handle.php';
?>

dbconnect.php establishes the connection to the database.
If there's an error, I'd like to redirect to a friendly error page, since the code can't continue.

my dbconnect.php page looks like this:
<?php
$conn = mysql_connect("localjost","root");  //misspelled to trigger error
if (!$conn)
  {
  $_SESSION['dberror'] = mysql_error();
 
        /* Redirect browser */
      header("Location: dberror.php");
      exit;
  }
 
$dbname = 'myown_db';
mysql_select_db($dbname);
?>

This is the result I get:

Warning: mysql_connect() [function.mysql-connect]: Unknown MySQL server host 'localjost' (1) in /Applications/XAMPP/xamppfiles/htdocs/mysite/inc/dbconnect.php on line 3

Warning: Cannot modify header information - headers already sent by (output started at /Applications/XAMPP/xamppfiles/htdocs/mysite/inc/dbconnect.php:3) in /Applications/XAMPP/xamppfiles/htdocs/mysite/inc/dbconnect.php on line 9

In ASP this was pretty easy to code.  i could redirect people to however many pages I needed to based on what error was triggered.  It doesn't appear that I can do that in PHP.
(or, at least it appears I need to do it in a much different way.)

Any help you can provide would be appreciated.

Thanks!!!
