There are a number of ways to prevent multiple form submissions.

A really easy way is to make the button disappear when it's clicked. Here's an example of how it's done:

<?php
<input 
   type="submit" 
   value="Click Me" 
   style="display:block;" 
   onclick="this.style.display='none'">

The inline CSS declaration display:block; must be there.

When the button is clicked, the onclick="this.style.display='none' attribute makes the submit button disappear.
