  // $file should include path and filename
  $filename = basename($file);
  $file_size = filesize($file);
  $content = chunk_split(base64_encode(file_get_contents($file))); 
  $uid = md5(uniqid(time()));
  $from = str_replace(array("
", "
"), '', $from); // to prevent email injection
  $header = "From: ".$from."
