    if ((($_FILES["file"]["type"] == "application/zip")
    || ($_FILES["file"]["type"] == "application/x-zip-compressed")
    || ($_FILES["file"]["type"] == "multipart/x-zip")
    || ($_FILES["file"]["type"] == "application/x-compressed")
    || ($_FILES["file"]["type"] == "application/octet-stream"))
    && ($_FILES["file"]["size"] < 20000000))

          if ($_FILES["file"]["error"] > 0)
         {
            echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
         }
         else
         {
            echo "Upload: " . $_FILES["file"]["name"] . "<br>";

         echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";


        if (file_exists("upload/" . $_FILES["file"]["name"]))
        {
           echo $_FILES["file"]["name"] . " already exists. ";
        }
        else
        {
          move_uploaded_file($_FILES["file"]["tmp_name"],"upload/". $_FILES["file"]  ["name"]);

        }
     }
     }
   else
   {
     echo "Invalid file(please upload zip file)";
     header("refresh: 1; upload.html"); 
    }
  }
else
{
  echo "please select a zip file";
  header("refresh: 2; upload.html");
