card numbers

[Anon]

Hi,

I know there is probably some easy way to do this, but I have not figured it out.

What I need to is when I display a credit card number back to the user after they have submitted them to me, how do I have the first 12 numbers display * and then the last four digets of the number like:

************1234

you know all of the ecommerce sites do.

I have a variable, say $ccnumber , how would I echo it back in the above formt.

Thanks for the help.

$new_ccnum = "************" . substr($ccnumber, 12);

That will give you a variable with 12 *'s followed by the 13,14,15, and 16th digit of your original variable.

Try:

<?php

$card = '9999888866661234';

print substr_replace( $card, '************', 0, 12 ) . "\n";

print '************' . substr( $card, 12, 4 ) . "\n";

?>

Both of these produce the output I believe you're looking for.

Of course, there are other ways you could do this....these are just 2 examples.
