PHP: How To Create a Unique #
<p>I've seen lots of examples of how to use uniqid() in PHP to create a unique string, but need to create a unique order number (integers only, no letters).</p>

<p>I liked the idea of uniqid() because from what I understand it uses date/time, so the chances of having another id created that is identical is nil.... (if I'm understanding the function correctly)</p>
