Tricky PHP Array - php

Question

I used stripe to return a Customer Object. I want to extract the bank account ID and save it in a database for later use. What is the proper syntax to access the array properly?
Here is what I have tried:
$bank_account=$customer->lastResponse['json']['sources']['data'][0]['id'];
I was told to try:
$bank_account=$customer->bank_accounts->data[0]['id'];
But that came up null as well...
Im not sure how to work with the object or what the right way to do this is.
I need the bank_account_id
This is what the var_dump($customer) looks like after some formatting and removing information that is not pertinent. I think I can either use a JSON decode or access the array called 'json' i dont know the proper syntax for either of those solutions. Help please (:

Answer 1

I think it should be:
$bank_account = $customer->sources->data[0]->id
If the customer has multiple fund sources, you may need to loop through the data array to find the one you want. $customer->sources->data[$i]->object will be "bank_account" for the source you want.

Answer 2

Pretty sure there is a getter in there. You can just use the properties you would expect on the object.
Example:
$customer_id = $customer->id;
$bank_account_id = $customer->sources->data[0]->id;
