function any_uploaded($name) {
  foreach ($_FILES[$name]['error'] as $ferror) {
    if ($ferror != UPLOAD_ERR_NO_FILE) {
      return true;
    }
  }
  return false;
}

if (any_uploaded('smth')) {
  // ..operating with $_FILES...
}

Yes, something like this, only that doesn't work - $FILES is always set.

Actually you'd need to iterate through your $_FILES and check for UPLOAD_ERR_NO_FILE in the error-key. See http://php.net/manual/en/features.file-upload.errors.php for more.

Apart from that, there are countless ways of checking if an array is empty! i.e. empty() or count()

just check for the file's name:

foreach($_FILES as $key => $val){
  if(strlen($_FILES[$key]['name']) > 0){
    //here we got a file from user
  }else{
    //no files received
  }
}
