Get last 4 digits of credit card after successful Stripe payment

Question

I have the following code that processes a charge on a users credit card using Stripe.

// Create the charge on Stripe's servers - this will charge the user's card
    try {
        $charge = Stripe_Charge::create(array(
          "amount" => $grandTotal, // amount in cents, again
          "currency" => "usd",
          "card" => $token,
          "description" => "Candy Kingdom Order")
        );
    } catch(Stripe_CardError $e) {
      // The card has been declined
    }

Now I want to be able to show the last 4 digits of the card that was used on the order confirmation page. But I want to do it in a way that it does NOT store the full card number. JUST the last 4. I'm not sure how to retrieve this information, if it's even possible. Pleas help?

The API Documentation has the answer you are looking for. $charge->card->last4 should have the value you are looking for. Using your example, the following would work:

$last4 = null;
try {
    $charge = Stripe_Charge::create(array(
      "amount" => $grandTotal, // amount in cents, again
      "currency" => "usd",
      "card" => $token,
      "description" => "Candy Kingdom Order")
    );
    $last4 = $charge->card->last4;
} catch(Stripe_CardError $e) {
  // The card has been declined
}
