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...:):D
