PHP：将notify.php从HTTP 1.0更改为1.1失败

Question

PayPal has mailed me that they will no longer support HTTP1.0 in a few days.

So i've changed my old PHP code:

$header = "POST /cgi-bin/webscr HTTP/1.0
";  
$header .= "Content-Type: application/x-www-form-urlencoded
";  
$header .= "Content-Length: " . strlen($req) . "

";  

to what they've recommended:

$header="POST /cgi-bin/webscr HTTP/1.1
";
$header .="Content-Type: application/x-www-form-urlencoded
";
$header .="Host: www.paypal.com
"; 
$header .="Connection: close

";

Now the notify.php don't work anymore :(

Any ideas?

Thanks!

Found this:

PayPal recently announced that they're going to "discontinue support for HTTP 1.0 protocol starting February 1, 2013." Today I ran into some problems implementing these changes. It turns out that the VERIFIED response code is now followed by a . So, the previous if (strcmp($res, "VERIFIED") == 0) { code no longer works by itself. I was able to solve this by trimming off the using $res = trim($res);.
