PHP ORMs and optimized relationship queries

I need a PHP ORM to work with relations well. Please consider code below in Zend:

$persons = new Persons();
$person = $persons->find(5)->current();
echo 'Name: '.$person->fullname;

$phones = $person->findDependentRowset('Phones');
foreach($phones as $phone)
    echo 'Phone: '.$phone->phonenumber;

Or code below in xPDO:

$person = $xpdo->getObject('Persons', 5);
echo 'Name: '.$person->get('fullname');

$phones = $person->getMany('Phones');
foreach($phones as $phone)
    echo 'Phone: '.$phone->get('phonenumber');

in both scripts, ORMs executes two queries as below:

SELECT * FROM persons WHERE id=5;
SELECT * FROM phones WHERE person=5;

It means one query for main object and one query for each relation but what i need is using ONE query for main object and its relations! xPDO can do it as below:

$person = $xpdo->getObjectGraph('Persons', '{"Phones":{}}', 5);
echo 'Name: '.$person->get('fullname');

foreach($person->Phones as $phone)
    echo 'Phone: '.$phone->get('phonenumber');

which executes this query:

SELECT * FROM persons
LEFT JOIN phones ON phones.person=persons.id
WHERE persons.id=5

This is great but its not possible to set fields to get from tables! it means in this case xPDO use "SELECT * " so if i get an object and its 4 relations, i will get all fields of all these tables!

So i need an ORM to execute query below for example above:

SELECT persons.fullname , phones.phonenumber FROM persons
LEFT JOIN phones ON phones.person=persons.id
WHERE persons.id=5

Doctrine can do it via DQL but i think Doctrine is not good for personal projects. Is there any PHP ORM to do this?

Thanks AHHP

Solution

xPDO can do it. You just have to adjust your thinking and your request.

Remember the objectGraph utilizes the class name of the object, where as the relationships in the graph are used in the graph and query.

 $criteria = $this->xpdo->newQuery('prefixClient');
            if (!empty($limit))
                $criteria->limit($limit);
            $criteria->where(array('Child.planid' => $this->getPrimaryKey(),
                                   'Child.active' => true,
                                   'GrandChild.someAttribute' => true,
                                   'GreatGrandChild.someOtherAttribute' => true,
                                   'suspended' => false
                             ));

            $out = $this->xpdo->getCollectionGraph('prefixClient', '{"Child":{"GrandChild":{"GreatGrandChild":{}}}}', $criteria);

You set the WHERE on any aspect of the relation, including the current object as show in the suspended => false line.

My book might help you a little in establishing your schema and relations. Objects should always be singular in nomenclature, whereas their relations can be plural (1:M) or singular (1:1).
