請查看我的Paypal IPN處理程序

Question

我為某人編寫了一個自動捐贈系統，以便在他的游戲服務器上玩的人可以輸入他們的信息，捐贈並自動添加到數據庫中。 它的工作很棒，但是我不是很懂PHP，所以我希望你們可以看看並告訴我還應該添加什么。 我需要在訂閱結束時刪除它們，我認為這是subscr_eot，但是我找不到使用它的任何好例子。 至於其余的我只是希望看起來還可以，謝謝！

<?php

// database
include_once('config.php');

//Connect
$db_connect = mysql_connect($DB_host, $DB_username, $DB_password) or die(mysql_error());
mysql_select_db($DB_name) or die(mysql_error());

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value)
{
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
