fsockopen() returning a weird error

[digitman]

Hi.
I'm trying to use the fscockopen function to integrate the PayPal IPN for a website. What I'm trying to do is to post some variables back to PayPal's website, and here is the one line that causes the error:

function fsockPost($data) { 
//$data is simply the $_POST array being passed to the function
$url="https://www.sandbox.paypal.com/cgi-bin/webscr";
 
//Parse url 
$web=parse_url($url); 
//build post string 
foreach($data as $i=>$v) { 
$postdata.= $i . "=" . urlencode($v) . "&"; 
}
$postdata.="cmd=_notify-validate";
//Set the port number
if($web[scheme] == "https") { $web[port]="443";  $ssl="ssl://"; } else { $web[port]="80"; }  
//Create paypal connection
$fp=@fsockopen($ssl . $web[host],$web[port],$errnum,$errstr,30); 
//Error checking
if(!$fp) { echo "$errnum: $errstr"; } 
 
//Post Data
else { 
 
  fputs($fp, "POST $web[path] HTTP/1.1\r\n"); 
  fputs($fp, "Host: $web[host]\r\n"); 
  fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); 
  fputs($fp, "Content-length: ".strlen($postdata)."\r\n"); 
  fputs($fp, "Connection: close\r\n\r\n"); 
  fputs($fp, $postdata . "\r\n\r\n"); 
//loop through the response from the server 
while(!feof($fp)) { $info[]=@fgets($fp, 1024); } 
//close fp - we are done with it 
fclose($fp); 
//break up results into a string
$info=implode(",",$info); 
}
return $info; 
   }

This line returns a really weird error..the error number is 0 and the error description is "Success". I don't know if this means an error or if this means success. Could the fsockopen be disabled at my server? What should I do about it?

This is really urgent please help.

I have had problems with fsockopen as well a while ago. Some hosts specifically disable this function for "security" reasons. Try using CURL or the Sockets extension if it is installed on your server

I fixed the problem.. for anyone else interested, I didn't have SSL installed at my server, therefore opening the SSL port was causing the error. I changed :

$url="https://www.sandbox.paypal.com/cgi-bin/webscr";

to

$url="http://www.sandbox.paypal.com/cgi-bin/webscr";

And now it works fine.
