get customer payment ids from CIM - php

Question

How can I get customer payment method ids from AuthorizeNetCIM_Response object?
There's a method in AuthorizeNetCIM_Response which is supposed to return payment method ids
public function getCustomerPaymentProfileIds()
{
$ids = (array)$this->xml->customerPaymentProfileIdList;
return $ids["numericString"];
}
but calling this function results in error
Notice: Undefined index: numericString
The response object outputs as:
AuthorizeNet_AuthorizeNetCIMResponse Object
(
[xml] => SimpleXMLElement Object
(
[messages] => SimpleXMLElement Object
(
[resultCode] => Ok
[message] => SimpleXMLElement Object
(
[code] => I00001
[text] => Successful.
)
)
[profile] => SimpleXMLElement Object
(
[merchantCustomerId] => 10
[email] => user#nine.com
[customerProfileId] => 25441529
[paymentProfiles] => Array
(
[0] => SimpleXMLElement Object
(
[billTo] => SimpleXMLElement Object
(
[firstName] =>
[lastName] =>
[address] =>
[city] =>
[zip] =>
[country] =>
[phoneNumber] =>
)
[customerPaymentProfileId] => 23298664
[payment] => SimpleXMLElement Object
(
[creditCard] => SimpleXMLElement Object
(
[cardNumber] => XXXX2224
[expirationDate] => XXXX
)
)
)
[1] => SimpleXMLElement Object
(
[customerType] => individual
[billTo] => SimpleXMLElement Object
(
[firstName] => Test
[lastName] => Individual
[company] => SimpleXMLElement Object
(
)
[address] =>
[city] =>
[state] =>
[zip] =>
[country] =>
[phoneNumber] => SimpleXMLElement Object
(
)
[faxNumber] => SimpleXMLElement Object
(
)
)
[customerPaymentProfileId] => 23299421
[payment] => SimpleXMLElement Object
(
[creditCard] => SimpleXMLElement Object
(
[cardNumber] => XXXX0027
[expirationDate] => XXXX
)
)
)
)
)
)
and I supposed to get the array of paymentProfiles as
$response->xml->profile->paymentProfiles;
but it only returning the first element of paymentProfiles not an array.

Answer 1

Since there can be more then one, as per your example, you need to loop through each profile to get that information:
$paymentProfileIds = array();
foreach ($response->xml->profile->paymentProfiles AS $profile) {
$paymentProfileIds[] = (string) $profile->customerPaymentProfileId;
}
print_r($paymentProfileIds);
