A Hydrator implementing Zend\Stdlib\Hydrator\HydratorInterface, completely based on Doctrine\Common
- can return cloned object
- let's you control what field should be extracted (recursively)
- can flat single keys
## Requirements
- [Zend Stdlib 2.2](https://github.com/zendframework/Component_ZendStdlib)
- [Doctrine\Common >=2.2](https://github.com/doctrine/common)
- [Doctrine\ORM >2.2](https://github.com/doctrine/doctrine2) or [Doctrine\ODM\MongoDB](https://github.com/doctrine/mongodb-odm)
## Installation
1. Add `"prolic/humus-doctrine-hydrator": "dev-master"` to your `composer.json`
2. Run `php composer.phar install`
## Example
Let's assume you want to hydrate an array to an object, and then you want to extract all it's internals
Example Class:
"User", has relationships to his "Locale", "Language" and "Address".
The address entity has also a relation to "Country".
```php
$hydrator = new \Humus\Doctrine\Hydrator\Hydrator(
$context->get('EntityManager'), // the entity manager
true, // yes, we want a cloned object, not the original one
array(
'id',
'name',
'firstname',
'fax',
'email',
'gender',
'locale' => array(
'name'
),
'preferred_contact_type' => array(
'id'
),
'address' => array(
'street',
'zip',
'city',
'country' => array(
'id',
'name'
),
),
'spoken_languages' => array(
'id',
),
), // we describe, what should be returned by extract, otherwise it could be that
// a) We dump the Unit of Work
// b) We dump half of the database
false //do not flat single keys
);
// we got some data
$data = array(
'id' => 5,
);
// we get the cloned address object,
// just switch the clone argument in constructor to false, in order to get the real object back
$address = $hydrator->hydrate($data, new \Application\Entity\Contact());
$result = $hydrator->extract($address);
var_dump($result);
// output:
array(6) {
["id"]=>
int(5)
["gender"]=>
string(4) "male"
["name"]=>
string(20) "Sascha-Oliver Prolic"
["locale"]=>
array(1) {
["name"]=>
string(10) "Deutsch DE"
}
["address"]=>
array(4) {
["street"]=>
string(13) "Sample Street"
["zip"]=>
string(5) "00000"
["city"]=>
string(6) "Berlin"
["country"]=>
array(2) {
["id"]=>
int(1)
["name"]=>
string(7) "Germany"
}
}
["spoken_languages"]=>
array(1) {
[0]=>
array(1) {
["id"]=>
int(1)
}
}
}
// Please note how the output changes (watch for locale) when you switch the "flatSingleKeys" flag to true
// in the constructor of the hydrator
