contact form with auto generated confirmation number

How about something like: $Confirm='CN_'.time().'_'.rand(0,9);

I added a single random number to the end of the string on the off chance there is a collision on the exact time a message is sent... It should not effect ordering or sorting and the time can easily be extracted from it. Anyway, my first thought for a quick, simple unique confirmation number.

Hi TheMadScientist, So Can i just echo out $confirm?

Hi TheMadScientist, So how would I include it to be sent both to recipient and sender so both parties can get same confirmation code.

Thanks for all your help.

Without seeing the code you are using I can't really tell you what to do, except to say, put the variable $confirm in the message body...

mail('recipient email','subject',"Confirmation Number: ".$confirm."\n\nmessage text",'headers');
