[SOLVED] Exxxing out parts of a String... Hmmmm...

[bri0987]

 

I need to "x" out part of a credit card...

 

So if the credit card is: 1111555567891234

 

I need it to echo:

 

xxxx-xxxx-xxxx-1234

 

 

Anyone know how to do this.

 

Thanks,

 

BRI

something like this should work

 

$intCardNo = "4111111111111111";

$strCardNo =  "xxxx-xxxx-xxxx-".substr($intCardNo, -4);

print $strCardNo;
