我有以下PHP PayPal IPN，它在几天前一直运行良好。
然而，自从昨晚以来，它突然停止工作，并且我在paypal沙盒ipn模拟器中测试多少次并不重要，它只是没有在MYSQL数据库中插入任何内容！
我没有更改我的php文件中的任何内容，所以我不明白为什么会出现这个问题。
这是我的全部代码：
<?php
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);
$murl = "http://".$_SERVER['HTTP_HOST'];
// Check to see there are posted variables coming into the script
if ($_SERVER['REQUEST_METHOD'] != "POST") die ("No Post Variables");
// Initialize the $req variable and add CMD key value pair
$req = 'cmd=_notify-validate';
// Read the post from PayPal
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// Now Post all of that back to PayPal's server using curl, and validate everything with PayPal
// We will use CURL instead of PHP for this for a more universally operable script (fsockopen has issues on some environments)
//$url = $paypal_url;
$url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
$curl_result=$curl_err='';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded", "Content-Length: " . strlen($req)));
curl_setopt($ch, CURLOPT_HEADER , 0);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$curl_result = @curl_exec($ch);
$curl_err = curl_error($ch);
curl_close($ch);
$req = str_replace("&", "\n", $req); // Make it a nice list in case we want to email it to ourselves for reporting
// Check that the result verifies
if (strpos($curl_result, "VERIFIED") !== false) {
$req .= "\n\nPaypal Verified OK";
} else {
$req .= "\n\nData NOT verified from Paypal!";
mail("myemail@yahoo.co.uk", "IPN interaction not verified", "$req", "From: myemail@yahoo.co.uk" );
exit();
}

任何帮助将不胜感激。
