Adding another thing to a mail form

1

I’ve been following this tutorial - http://www.tutorial5.com/content/view/82/42 on making a mail form -

it works no problem but the thing is… I want to add in a field for the person to enter their phone number, I edited the php code to look like this

<?php
@extract($_POST);
$name = stripslashes($name);
$email = stripslashes($email);
$subject = stripslashes($subject);
$phone = stripslashes($phone);
$text = stripslashes($text);
mail(' info@suzyjohnston.co.uk This e-mail address is being protected from spam bots, you need JavaScript enabled to view it ',$subject,$phone,$text,"From: $name <$email>");
echo("Thank you for your interest, your e-mail was sent.");
?>

As you can see I added in this code to the above…

$phone = stripslashes($phone);

',$subject,$phone,$text,"From: $name <$email>");

but when I add this into the code it messes up who the sender of the email was - it just says in the ‘From’ field
