Paypal 샌드 박스 IPN이 내 데이터베이스 테이블을 업데이트하지 않습니다

Question

저는 페이팔 IPN을했는데 데이터베이스에 아무것도 표시되지 않았습니다. 여기 내 단추가 (나는 그것을 reoccuring 기반으로 만들었습니다) 내 코드, 아무도 내가 잘못 갔는지 보지? 누구는 나에게이 문제

<?php 
$conn = mysql_connect('localhost', 'USERNAME', 'PASSWORD'); 
if(!$conn) { die("Could not connect: ".mysql_error()); } 

$database = mysql_select_db('fbkidsonlinedb', $conn); 
if(!$database) { die("Can't use database: ".mysql_error()); }

왜 호스트에 대한 링크를 할당 할를 해결하는 데 도움이 될 수 : 어쨌든

$header .= "Host:http://www.sandbox.paypal.com:443\r\n"; 

:

$header .= "Host: <!-- w --><a class="postlink" href="http://www.sandbox.paypal.com:443">www.sandbox.paypal.com:443</a><!-- w -->\r\n"; 

그게 있어야한다 생각 PayPal에 익숙하지 않은 분, 실수라면 미안 해요
