Question

我试图简单计算条纹响应中有多少退款，但count()不起作用，我真的不知道实现此目的的任何其他方法

有人能指出我正确的方向吗？

$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));

这是$retrieve_event

Answer 1

这就是你尝试输出计数的方式。 This example outputs 3：

echo count($refund_array);
exit;

Whereas this example doesn't：

die(count($refund_array));

原因是因为您只是将整数传入die()。 From the manual：

如果status是一个整数，该值将用作退出状态而不打印。退出状态应在0到254范围内，退出状态255由PHP保留，不得使用。状态0用于成功终止程序。

This example有效，因为该消息是一个字符串：

die('Count: ' . count($refund_array)); // Count: 3

...或：

die((string) count($refund_array));    // 3

Answer 2

count()只需要转换为字符串：

die((string) count($refund_array));

Answer 3

根据2014-06-17上发布的新版Stripe API，针对Charges方法修改了退款对象。

现在，您可以使用退款对象中的total_count参数直接获取退款计数。

DATA-＆GT;对象 - ＆GT;退还的款项＆GT; TOTAL_COUNT
