Hello. I'm having the most difficult time trying to get the Paypals IPN subscription

Id. This is my IPN  page.

<?php
  // 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";
}

  
// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);


 

if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment
  if("susbcr_signup" == $_POST['txn_type']){

      $_id = $_POST['subscr_id'];
  

 
    $websites= "websites";
    $database = "k29803_1";
   mysql_connect("localhost", $username, $password) or die(mysql_error());
   mysql_select_db($database);

  $query = "SELECT * FROM users WHERE username= 'drahoslava' AND password = 'drah0slava'";
  $results = mysql_query($query)or die(mysql_error());
    if(mysql_num_rows($results)==1){
        $add_credits = "UPDATE users SET hash = '$_id'
        WHERE username= 'drahoslava' AND password = 'drah0slava'";
        mysql_query($add_credits) or die(mysql_error());
      echo 'done';
         

      }

}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
  }
  ?>

This is my form

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="6ZZUDQCUUXGMS">

fclose needs to move, and mysql_free_result needs to be added. common mistake with mysql_free_result, the examples don't have it, but they should, code doesn't work without it.
