PHP PayPal IPN

How exactly is this PHP paypal IPN used?
I found a lot of code online, someone wrote a good class, directly can call on it, the bottom of the reply is also can be used.
Why can't I use it? I've been testing in the sandbox.

is not in the Sandbox test tool point send IPN, and then open their own server ipn.php on the test?
Or do I have a wrong test method in the sandbox?

Who used IPN, teach me how to use AH

Reply to discussion (solution)

No one will know, right?????
I'm so worried.

The method is wrong.

Do you have a sandbox account?

IPN is essentially a URL callback function, and the method you test is right.
It should be noted that the URL port of the callback must be 80

Thank you I have solved, my method is wrong, do not need to refresh ipn.php that page, refresh is useless.
