PHP Reference/Order Code Generator

[trivia89]

Hello All. Before I start....thanks for your patience.
I need to have my order form (PHP) generate a reference or order form that's unique when the user clicks the SUBMIT button (the form then gets email to me in text). I figured using a time/date stamp would make it unique enough.

I pulled this off of another forum...

$reference_num_date = date("ymdHis",$reference_num_secs);

Apparently, it generates a code like this... 070125230302

Which is Jan 25, 2007 11:03:02pm.

This is exactly what I can use. The problem is, how do I get this reference number to appear on the "Thank You for your order" page and have it emailed to me along with the rest of the order?

Please help!! THANKS

Found a way...

use $time() function to give you a Unix Time Stamp.

It's a 10 digit number in seconds from 1970.

Works for me. Maybe this might help others.

THANKS...
