我在沙盒模式下使用PayPal IPN，但由于某种原因，此代码不起作用。
我想发生的是它说"已验证"以在括号之间执行操作。但它不是，我不知道任何PhP，但我需要这个来为我的钱工作。
这是我商店的索引.php

我认为您的网址是错误的。 尝试放置
$fh = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
而不是 '$fh = fsockopen ('ssl://www.paypal.com'， 443， $errno， $errstr， 30(;
在您的测试中，立即付款按钮也放 sandbox.paypal.com/blahglah">
所以把 sandbox.paypal.com.....而不是 paypal.com....
