Contact Us form redirect to home page after submit (Web Development)

I have developed a contact us page and also PHP code that works perfect. Know the only problem is that after submitting the form it shows only "Message sent" on a new page. I want that after submitting the form page will redirect back to home page. It is only one page "Landing Page". Here is the PHP code.`

<?php

if(!$_POST) exit;

$email = $_POST['email'];


//$error[] = preg_match('/\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i', $_POST['email']) ? '' : 'INVALID EMAIL ADDRESS';
if(!eregi("^[a-z0-9]+([_\\.-][a-z0-9]+)*" ."@"."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a-z]{2,}"."$",$email )){
    $error.="Invalid email address entered";
    $errors=1;
}
if($errors==1) echo $error;
else{
    $values = array ('name','email','message','phone');
    $required = array('name','email','message','phone');

    $your_email = "todd@toddandersonhomes.com";
    $email_subject = "Free Credit Report: ".$_POST['subject'];
    $email_content = "Following is the free credit report detail from client:\n";

    foreach($values as $key => $value){
      if(in_array($value,$required)){
        if ($key != 'subject' && $key != 'company') {
          if( empty($_POST[$value]) ) { echo 'PLEASE FILL IN REQUIRED FIELDS'; exit; }
        }
        $email_content .= $value.': '.$_POST[$value]."\n";
      }
    }

    if(@mail($your_email,$email_subject,$email_content)) {
        echo 'Message sent!'; 
    } else {
        echo 'ERROR!';
    }
}
?>

HTML Code:

 <form action="contact.php" method="post">

                        <div class="formele">
                <ul>
                    <li>
                    <label>Name:</label>
                    <input type="text" id="name" name="name" class="text2" />
                    </li>
                    <li>
                    <label>Telephone:</label>
                    <input id="name" type="text" name="phone" class="text2" />
                    </li>
                    <li>
                    <label>E-mail:</label>
                    <input id="name" type="text" name="email" class="text2" />                    
                    </li>
                    <li>
                    <label>Address:</label>
                    <input id="name" type="text" name="message" class="text2" />                    
                    </li>

                    <li class="button">
                    <input type="image" type="text" src="images/submit.png" />                   
                    </li>
                </ul>            
            </div><!--Contact Form Ends Here -->
