Update CC info of Braintree in PHP - php

Question

I am trying to update CC info of braintree but function provided in docs is not working . and I am unable to find out the reason.
Here is my function :
public function updateCC(){
$fname = $this->input->get_post('fname');
$lname = $this->input->get_post('lname');
$expirationYear = $this->input->get_post('expirationYear');
$expirationMonth = $this->input->get_post('expirationMonth');
$cardholderName = $this->input->get_post('cardholderName');
$cvv = $this->input->get_post('cvv');
$cc_no = $this->input->get_post('cc_no');
$token = $this->input->get_post('token');
$BTCustomerID = $this->input->get_post('BTCustomerID ');
$result = Braintree_Customer::update(
$BTCustomerID,
(
'firstName' => $fname,
'lastName' => $lname,
'creditCard' => (
'paymentMethodNonce' => 'fake-valid-nonce',
'options' => (
'updateExistingToken' => $token,
'verifyCard' => true
)
)
));
echo json_encode(array('error'=>-1));
}
Due to this code my application is crashing .
$result = Braintree_Customer::update(
$BTCustomerID,
(
'firstName' => $fname,
'lastName' => $lname,
'creditCard' => (
'paymentMethodNonce' => 'fake-valid-nonce',
'options' => (
'updateExistingToken' => $token,
'verifyCard' => true,
)
)
));

I’m a developer at Braintree. In your call to Braintree_Customer::update(), paymentMethodNonce must be passed inside of creditCard at the same level as options. In your code you are passing the it inside of options. See this code example for reference.
