[SOLVED] Print last four digits of credit card number only

[JCS1988]

I am designing an eCommerce site as a class project, I have gotten most of it done by now but I am just working on the last few steps. Right now I am working on a page that displays an overview of the customers order. It pulls all the information from the database and displays it, but for the billing info section I just wanted to print out the card info and then the number like **** **** **** 5784. I'm sure most of you have seen this done on other shopping web sites, so I was curious as to how I would go about doing something like that. The number is stored in the "users" table  under the field "card_number". Their is no encryption as of right now, I am keeping things simple since this isn't going to be an actual site. Right now on the confirmation page I have a recordset in Dreamweaver that calls in all information from the users table, so it will be there already I guess I just need to change how it's printed. Any help would be great, thanks in advance!

you could make some code like this

$card_display="**** **** **** ".substr($card_number,12,4);

Looks simple enough, how could I replace this code with that. I see the code I have refers to a rowset, Dreamweaver set it all up for me.

 

<?php echo $row_userSet['card_number']; ?>

[ratcateme]

<?php echo $row_userSet['card_number']; ?>

this should do it:

<?php echo "**** **** **** ".substr($row_userSet['card_number'],12,4); ?>
