Question

I want to format the credit cards like below when i display it,

Eg:

1234 4567 9874 1222

as

1xxx xxxx xxx 1222

Is there any formatting function like this in Yii ?

Answer 1

And you could also use preg_replace :

$card='1234 4567 9874 1222';
$xcard = preg_replace('/^([0-9])([- 0-9]+)([0-9]{4})$/', '${1}xxx xxxx xxxx ${3}', $card);

This regex will also take care of hyphens.

There is no in-built function in Yii.
