note 47282 added to function.str-replace

For printing invoices with only the last 4 digits of a credit card showing, we used both str_repeat and str_replace functions as follows: <?php echo substr_replace($var, str_repeat("*", strlen($var)-4), 0, -4); ?> $var being the raw credit card number and '*' being the desired placeholder for the other digits. Enjoy!
