Replacing characters

[kjc]

Is there a php function (or this could be for javascript instead), that would replace say the first 12 characters of a 16 character word into *.

I have credit cards stored on a database, but want to display them over secure connection, but only the last chars, leaving the first 12 chars as *.

Any ideas?

Yes.


$cardNum = "1234567901234567890";
echo preg_replace('/^(.){1,12}/', str_repeat("*", 12), $cardNum);

str_repeat()

we live and learn ...(had never heard of that one before!)
