einzelne Getter oder eine Methode - Datenrückgabe Struktur

[jobo]

Hallo,

Naja, active-record wäre das dann, oder? Kann sein, muss nicht. Dann regelt die Klasse den Zugriff auf die Datensätze, oder? ZF kennt auch eine DB_Row-Klasse glaub ich. Aber fetchAssoc() gibt bestimmt die Zeilenwerte als assoziatives _Array_ wieder.

http://framework.zend.com/manual/de/zend.db.table.row.html

bzw.

http://framework.zend.com/apidoc/core/ und darin eben die Klasse:

http://framework.zend.com/apidoc/core/Zend_Db/Table/Zend_Db_Table_Row.html

Der Zugriff auf Daten ist über die Methoden geregelt. __get/set wird auch - wie ich finde garnicht so unübersichtlich - genutzt.

  
abstract class Zend_Db_Table_Row_Abstract implements ArrayAccess  
{  
  
    /**  
     * The data for each column in the row (column_name => value).  
     * The keys must match the physical names of columns in the  
     * table for which this row is defined.  
     *  
     * @var array  
     */  
    protected $_data = array();  
  
    /**  
     * This is set to a copy of $_data when the data is fetched from

     * when dirty data is posted to the database with save().  
     *

    protected $_table = null;

        }
