Preventing redirects when submitting a form

I recently (with a little help) wrote this simple form in an email script. It works, the only problem is that at startup it redirects to the included PHP script. Does anyone have any ideas on how to stop this, and instead just show a thank-you note on the original page?

index.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Megaform</title>
</head>

<body>
  <?php include 'form.php' ?>
</body>
</html>

form.php

<form name="email" method="post" action="email.php">
  <p>
    <label for="name">Full Name</label>
    <input type="text" name="name" id="name">
  </p>
  <p>
    <label for="email">Email Address</label>
    <input type="text" name="email" id="email">
  </p>
  <p>
    <label for="phone">Phone Number</label>
    <input type="text" name="phone" id="phone">
  </p>
  <p>
    <label for="subject">Subject</label>
    <input type="text" name="subject" id="subject">
  </p>
  <p>
    <label for="message">Message<br>
    </label>
    <textarea name="message" id="message" cols="45" rows="5"></textarea>
  </p>
  <p><input type="submit" name="send" id="send" value="Submit"><input type="reset" name="send" id="send" value="Reset">
  </p>
</form>

email.php

<?php  

// Get the Variables
  $name = $_POST['name'];
  $visitor_email = $_POST['email'];
  $phone = $_POST['phone'];
  $subject = $_POST['subject'];
  $message = $_POST['message'];


// Validate against spammers
function IsInjected($str)
{
    $injections = array('(\n+)',
           '(\r+)',
           '(\t+)',
           '(%0A+)',
           '(%0D+)',
           '(%08+)',
           '(%09+)'
           );

    $inject = join('|', $injections);
    $inject = "/$inject/i";

    if(preg_match($inject,$str))
    {
      return true;
    }
    else
    {
      return false;
    }
}

if(IsInjected($visitor_email))
{
    echo "Bad email value!";
    exit;
}


// Compose the Email
    $email_from = 'a@b.com';  // Set a valid email address that the form can use

    $email_subject = "New Form submission - $subject";  //  Change the message subject here

    $email_body = "You have received a new message from $name ($phone) .\n Here is the message:\n $message";


// Send The Email
  $to = "c@d.com";  // Set a valid email address to send the form to

  $headers = "From: $email_from \r\n";

  $headers .= "Reply-To: $visitor_email \r\n";

  mail($to,$email_subject,$email_body,$headers);

?>
<p>Thankyou for your email.</p>

change your form tag to say:

<form name="email" method="post" action="index.php">

and change your index php to say:

<body>
<?php
    if (isset($_POST['email'])) {
        include 'email.php';
    } else {
        include 'form.php';
    }
?>
</body>

So, if the form was submitted, send an email, otherwise show the form.

}

form.php

Put this at the end of form.php

header("url: index.php");

or even:

header("url: index.php?sent=true");

And in index.php you can have

if($_GET['sent']){
   echo "Message Sent.";
}
