php - What is the best way to solve this problem in a model? -

-

i come across lot, , have been curious if there better way.

consider (example only, assume oo query builder)

class dogs extends pets {      public function getall() {         return $this->parserows($this->db->get('dogs'));     }      public function getbig() {         return $this->parserows($this->db->get('dogs')->where('size', '>', 10));     }      public function getsmelly() {         return $this->parserows($this->db->get('dogs')->where('smell', '=', 'bad'));     }      private function parserows($rows) {         foreach($rows &$row) {             $row['id'] = (int) $row['id'];             $row['categoryname'] = categories::getbyid($row['categoryid']);         }         return $rows;     }  }

basically, need use lot of database queries, need go through post-processing assign things them. have been using pattern above.

is best practice way this?

to me public interface seems decent. regarding implementation, there lot said, object-relational mappers 1 of cornerstones of modern programming imho.

if learn more alternate ways of implementing orm, i'd suggest looking @ open-source frameworks such doctrine or cakephp's orm.

one note i'd add regarding private implementation: if categories::getbyid roundtrip call database, inefficient, table many dogs lead (at least) many db calls, suboptimal. why orms ones mentioned above allow developer specify associations (eg. dog has category) , automatically generate "left join" statements.
