xxxxxxxx1234

[zang8027]

ok, so for my portfolio, I have a php site. What i want to know is how to only show a certain part of what the user submitted (credit card)

 

So say the user put in 1234567 as his or her credit card number. On the confirmation page, I want it to say: XXXXX67

 

How can I do that  ???

use substr()

 $card = "xxxxx".substr($card_num,5,2);

 

Scott.

[derekmcd]

$cardnum = "XXXXXX".substr($_POST['creditcard_num'], -2);

you can try this as well:

 

$var = "4111111111111111";

print str_repeat("x", strlen($var)-4).substr($var, strlen($var)-4, strlen($var));
