Mask credit card number

While working with credit cards it often needed to mask the number or card holder name. Here's the class you may use for that purpose. It is possible to configure mask symbol and the length of shown chars.


use Payum\Core\Security\Util\Mask;

echo Mask::mask("3456-7890-1234-5678");
// 3XXX-XXXX-XXXX-5678

echo Mask::mask("4567890123456789", "*");
// 4***********6789

echo Mask::mask("4928-9012-abcd-3456", null, 8);
// 4XXX-XXXX-abcd-3456
