Counting array in API JSON Response - php

Question

I'm trying to do a simple count of how many refunds are in my Stripe Response but count() isn't working and I don't really know any other way of achieving this.
Could anyone point me in the right direction?
$retrieve_event = Stripe_Event::retrieve("evt_00000000000000");
$event_json_id = json_decode($retrieve_event);
$refund_array = $event_json_id->{'data'}->{'object'}->{'refunds'};
die(count($refund_array));
This is the response of $retrieve_event

Answer 1

It's just the way you're trying to output the count. This example outputs 3:
echo count($refund_array);
exit;
Whereas this example doesn't:
die(count($refund_array));
The reason is because you're simply passing in an integer into die(). From the manual:
If status is an integer, that value will be used as the exit status and not printed. Exit statuses should be in the range 0 to 254, the exit status 255 is reserved by PHP and shall not be used. The status 0 is used to terminate the program successfully.
This example works because the message is a string:
die('Count: ' . count($refund_array)); // Count: 3
...or:
die((string) count($refund_array)); // 3

Answer 2

The count() just needs to be cast as a string:
die((string) count($refund_array));

Answer 3

As per new version of Stripe API which was released on 2014-06-17, Refunds object is modified for Charges Method.
Now you can directly get refund count using total_count parameter in refunds object.
data->object->refund->total_count
