我已经被正确地发送邮件到我的文件的IPN，我已经证实，我接受了他们，首先这里是我的代码：贝宝IPN验证
echo "test";
// Response from Paypal
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
$req .= "&$key=$value";
}
// assign posted variables to local variables
$data['item_name'] = $_POST['item_name'];
$data['item_number'] = $_POST['item_number'];
$data['payment_status'] = $_POST['payment_status'];
$data['payment_amount'] = $_POST['mc_gross'];
$data['payment_currency'] = $_POST['mc_currency'];
$data['txn_id'] = $_POST['txn_id'];
$data['receiver_email'] = $_POST['receiver_email'];
$data['payer_email'] = $_POST['payer_email'];
$data['custom'] = $_POST['custom'];
// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.1\r\n";
$header .= "Host: www.sanbox.paypal.com\r\n";
$header .= "Accept: */*\r\n";
$header .= "Connection: Close\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "\r\n";
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
if ($fp === FALSE) {
exit("Could not open socket");
}else{
if (!$fp) {
echo "Error code: 200";
}else{
fputs ($fp, $header . $req);
$res = stream_get_contents($fp, 2048);
echo "test2";
$res = trim($res);
if (strcmp($res, "VERIFIED") == 0){
echo "test3";
// Used for debugging
//@mail("[email protected]", "PAYPAL DEBUGGING", "Verified Response<br />data = <pre>".print_r($post, true)."</pre>");
// Validate payment (Check unique txnid & correct price)
$valid_txnid = check_txnid($data['txn_id']);
$valid_price = check_price($data['payment_amount'], $data['item_number']);
// PAYMENT VALIDATED & VERIFIED!
if($valid_txnid && $valid_price){
$orderid = updatePayments($data);
if($orderid){
echo "thanks for your payment!";
$lel = mysqli_query($con,"UPDATE stats SET stats.bankedgold = 10000 WHERE stats.id = $id4");
// Payment has been made & successfully inserted into the Database
}else{
echo "Error code: 100";
// E-mail admin or alert user
}
}else{
echo "Error code: 130";
// Payment made but data has been changed
// E-mail admin or alert user
}
}else if (strcmp ($res, "INVALID") == 0) {
echo "Error code: 170";
// PAYMENT INVALID & INVESTIGATE MANUALY!
// E-mail admin or alert user
// Used for debugging
//@mail("[email protected]", "PAYPAL DEBUGGING", "Invalid Response<br />data = <pre>".print_r($post, true)."</pre>");
}
echo strcmp($res,"VERIFIED" == 0);
fclose ($fp);
}
}
}
现在，$ RES给人的var_dump：

但我需要它说只是验证或无效，所以我可以确定从那里做什么。
对我来说一个简单的解决方法是添加“strpos”，只是看看它是否包含单词，但我想向您的专家证实，这将是一个很好的解决方案？
