Chapter 8: Working with Models 110
Now consider the DQL equivalent of the SQL query we used:
Listing
8-38
// test.php
// ...
$q = Doctrine_Query::create()
->select('u.id, u.username, p.phonenumber')
->from('User u')
->leftJoin('u.Phonenumbers p');
$results = $q->execute(array(), Doctrine_Core::HYDRATE_ARRAY);
print_r($results);
The structure of this hydrated array would look like:
Listing
8-39
$ php test.php
Array
(
[0] => Array
(
[id] => 1
[username] =>
[Phonenumbers] => Array
(
[0] => Array
(
[id] => 1
[phonenumber] => 123 123
)
[1] => Array
(
[id] => 2
[phonenumber] => 456 123
)
[2] => Array
(
[id] => 3
[phonenumber] => 123 777
)
)
)
)
// ...
This structure also applies to the hydration of objects(records) which is the default hydration
mode of Doctrine. The only differences are that the individual elements are represented as
Doctrine_Record objects and the arrays converted into Doctrine_Collection objects.
Whether dealing with arrays or objects you can:
1. Iterate over the results using foreach
2. Access individual elements using array access brackets
3. Get the number of elements using count() function
4. Check if given element exists using isset()
