PHP in Email Template v3.0

I can't work out how to have php in the email template in version 3.0.

In v2.x I add the following code to the email template, but with 3.0 wysiwyg editor it rmoves my php code. Can any one help me to get this to work with 3.0?

<?php if($_POST['txtPhone'] != "") echo "<b>Phone</b>: ".$_POST['txtPhone']."<br>"; ?>

Hi, in the emails setup page, choose the email which you want to switch OFF the editor for, at the Email properties section you can see a switch for the editor for this email's template, note that you must click apply then save the whole form so that page reloads and changes take place!
