Using PHP > automatic redirection to previous page

1

hi! i was wondering how to use php for automatic redirection to a page on the website

basically, the visitors first fill out a form, and the form gets e-mailed to me and takes the visitors to a page saying “Thank you for filling out the form”.

This form e-mail thing is done using php … and i was wondering how to incorporate a redirection code in the following code so that afer submitting a form, the user goes to the page thats says “thank you …” and redirects the user back in 3 seconds to the a different page

<?PHP 
$to = "BLABLA@gmail.com"; 
$subject = "Submit a FORM";
$headers = "From: Form Mailer";
$forward = 0;
$location = "";

$date = date ("l, F jS, Y"); 
$time = date ("h:i A"); 



$msg = "Below is the result of your feedback form. It was submitted on $date at $time.

"; 

if ($_SERVER['REQUEST_METHOD'] == "POST") {
    foreach ($_POST as $key => $value) { 
        $msg .= ucfirst ($key) ." : ". $value . "
"; 
    }
}
else {
    foreach ($_GET as $key => $value) { 
        $msg .= ucfirst ($key) ." : ". $value . "
"; 
    }
}

mail($to, $subject, $msg, $headers); 
if ($forward == 1) { 
    header ("Location:$location"); 
} 
else { 
    echo "Thank you for submitting your review."; 
} 

?>

THANX A LOT FOR HELPING!!
