Question

I use kohana and when you try to fetch data from database it returns class variables(like $user->firstname) as a database data. User table have a 12 columns and i fetch 8 columns but at this point some of columuns maybe empty(like $user->phone). How can i found empty column number ?(Proper way..)

Thanks A Lot

Generically, you could try something like:

/**
 * Count number of empty data members in a row object.
 */
function countEmpty($row){
  $fields = array_keys($row->as_array());
  $cnt = 0;
  foreach($fields as $f){
    if (empty($row->$f)) $cnt++;
  }
  return $cnt;
}
