doctrine - DDD PHP Doctrine2 - Mapping -

i hear how peoploe map domain objects data mapper pattern in doctrine2. went problem, when aggregates use clean php array , use php functions work array array_shift example. anyway till started integrate doctrine mappings domain entities. problem how doctrine works assosciations between entities. whenever aggregate root had 1 many relationship (or other tbh), doctrine used arraycollection class on that, instead of normal array. use 1 of methods toarray(), have check first in domain object if doctrine collections class, dirty. anyway chose in aggregate repository, before returning class. made reflection class set property public , replaced clean php array. works less dirty, still dont tbh. question is, how guys handle limitations od doctrine or maybe there no limitation :). , next question, if guys use doctrine arraycollection in domain classes?

what using array for?

i suspect problem using arrays instead of objects. objects should reflect domain , provide methods exists in domain. if replacing real world behaviour arrays not following ddd principles.

simple example:

/**  *  * @orm\table(name="sales_flat_order")  * @orm\entity(repositoryclass="candle\orderbundle\repository\mage\orderrepository")  */ class order implements orderinterface {      /**      * @orm\onetomany(targetentity="orderitem", mappedby="order", cascade={"persist"})      *       * @var orderitem[]      */     private $orderitems;      /**      * constructor.      */     public function __construct()     {         $this->orderitems = new arraycollection();     }      /**      * check if items marked scanned       *       * @param integer $warehouseid warehouse id check for.       *       * @return boolean      */     public function isorderscancompleted($warehouseid)     {         foreach ($this->orderitems $orderitem) {             if ($orderitem->getwarehouseid() == $warehouseid                 && !$orderitem->isscancomplete()) {                 return false;             }         }          return true;     } } 

i have iterated through array of db values of related orderitems , check values constitute "isscancomplete" flag, decided implement , encapsulate in orderitem class. hence no need array of values.
