A different service for my Flex app using Zend_Amf - apache-flex

Question

I have an iterator service that works fine already and returns a correctly structured values to my flex application through my Zend Amf server
$contacts = array();
mysql_connect( 'localhost', 'root', 'test' );
mysql_select_db( 'test' );
$res = mysql_query( 'SELECT * FROM contact' );
while( $contact = mysql_fetch_assoc($res) ) {
$contacts []= $contact;
}
return $contacts;
However I would like to adjust this so that I can leverage my MVC structure and achieve the same results.
I have placed an excerpt that can be brought to working condition
$contacts = array();
$table = new Model_DbTable_Contact();
$result = $table->fetchAll();
//Return an array to be consumed by my flex application
foreach ($result as $row)
{
/*do something*/
}
return $contacts;

Answer 1

You'll want to look into ValueObjects. Zend_Amf supports those, and it's a good idea to use that. That way you can have objects that are native to both PHP and Flex.
$server->setClassMap('ContactVO', 'Contact');
Your Flex would then have a class:
[Bindable]
[RemoteClass(alias="Contact")]
public class ContactVO
{
}
Would tell your server that you're going to map your Contact class to ContactVO in Flex.
then you could do:
$data = array();
foreach ($result as $row)
{
$data[] = new Contact($row);
//assuming the Contact constructor parses the array data
}
return $data;
and your Contact objects would get to Flex as ContactVO objects

So here I have a function in the logical model for a database table:
public function fetchAll() {
$resultSet = $this->getDbTable()->fetchAll();
$entries = array();
foreach( $resultSet as $row ) {
$entry = new Model_ClosingData();
$entry->setId($row->id)
->setContractMonth($row->monthId)
->setCommodity($row->commodityId)
->setDate($row->date)
->setPrice($row->price)
->setVolume($row->volume)
->setOutstandingInterest($row->outstandingInterest);
$entries[] = $entry;
}
return $entries;
}
