You may use $_GET['confirmations'], here is a good example,

Code:

if ($_GET['confirmations'] >= 4) {              // change 4 to whatever number you want
  //Add to the database

  //Delete from pending

  if ($result) {
        echo "*ok*";
  }
} else {
   //Waiting for confirmations
   //create a pending entry

   echo "Waiting for confirmations";
}
