Stripe error handling on PHP-Collection of common programming errors

I think there is more than these exceptions (Stripe_InvalidRequestError and Stripe_Error) to catch.

The code below is from Stripe’s web site. Probably, these additional exceptions, which you didn’t consider, occurs and your code fails sometimes.

try {
  // Use Stripe's bindings...
} catch(Stripe_CardError $e) {
  // Since it's a decline, Stripe_CardError will be caught
  $body = $e->getJsonBody();
  $err  = $body['error'];

  print('Status is:' . $e->getHttpStatus() . "\n");
  print('Type is:' . $err['type'] . "\n");
  print('Code is:' . $err['code'] . "\n");
  // param is '' in this case
  print('Param is:' . $err['param'] . "\n");
  print('Message is:' . $err['message'] . "\n");
} catch (Stripe_InvalidRequestError $e) {
  // Invalid parameters were supplied to Stripe's API
} catch (Stripe_AuthenticationError $e) {
  // Authentication with Stripe's API failed
  // (maybe you changed API keys recently)
} catch (Stripe_ApiConnectionError $e) {
  // Network communication with Stripe failed
} catch (Stripe_Error $e) {
  // Display a very generic error to the user, and maybe send
  // yourself an email
} catch (Exception $e) {
  // Something else happened, completely unrelated to Stripe
}

EDIT:

try {
    $charge = Stripe_Charge::create(array(
    "amount" => $clientPriceStripe, // amount in cents
    "currency" => "usd",
    "customer" => $customer->id,
    "description" => $description));
    $success = 1;
    $paymentProcessor="Credit card (www.stripe.com)";
} catch(Stripe_CardError $e) {
  $error1 = $e->getMessage();
} catch (Stripe_InvalidRequestError $e) {
  // Invalid parameters were supplied to Stripe's API
  $error2 = $e->getMessage();
} catch (Stripe_AuthenticationError $e) {
  // Authentication with Stripe's API failed
  $error3 = $e->getMessage();
} catch (Stripe_ApiConnectionError $e) {
  // Network communication with Stripe failed
  $error4 = $e->getMessage();
} catch (Stripe_Error $e) {
  // Display a very generic error to the user, and maybe send
  // yourself an email
  $error5 = $e->getMessage();
} catch (Exception $e) {
  // Something else happened, completely unrelated to Stripe
  $error6 = $e->getMessage();
}

if ($success!=1)
{
    $_SESSION['error1'] = $error1;
    $_SESSION['error2'] = $error2;
    $_SESSION['error3'] = $error3;
    $_SESSION['error4'] = $error4;
    $_SESSION['error5'] = $error5;
    $_SESSION['error6'] = $error6;
    header('Location: checkout.php');
    exit();
}

Now, you will catch all possible exceptions and you can display error message as you wish. And also $error6 is for unrelated exceptions.
