想要将doctrine实体对象转换为普通数组,这是我的代码到目前为止,
$demo = $this->doctrine->em->find('Entity\User',2);
获取实体对象,
Entity\User Object
(
[id:Entity\User:private] => 2
[username:Entity\User:private] => TestUser
[password:Entity\User:private] => 950715f3f83e20ee154995cd5a89ac75
[email:Entity\User:private] => [email protected]
[firm_id:Entity\User:private] => Entity\Firm Object
(
[id:Entity\Firm:private] => 16
[company_name:Entity\Firm:private] => TestFirm
[company_detail:Entity\Firm:private] => India
[created_at:Entity\Firm:private] => DateTime Object
(
[date] => 2014-08-01 18:16:08
[timezone_type] => 3
[timezone] => Europe/Paris
)
[user:Entity\Firm:private] =>
)
[created_at:Entity\User:private] => DateTime Object
(
[date] => 2014-08-01 15:12:36
[timezone_type] => 3
[timezone] => Europe/Paris
)
[updated_at:Entity\User:private] => DateTime Object
(
[date] => 2014-08-01 15:12:36
[timezone_type] => 3
[timezone] => Europe/Paris
)
[firm:protected] =>
) ,
试过this,但根据我的要求,不想使用doctrine_query。谢谢。
你可以尝试这样的事情,
$result = $this->em->createQueryBuilder();
$app_code = $result->select('p')
->from('YourUserBundle:User', 'p')
->where('p.id= :id')
->setParameter('id', 2)
->getQuery()
->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);
其他方式,
$this->em->getRepository('YourUserBundle:User')
->findBy(array('id'=>1));
上面将返回一个数组但包含doctrine对象。返回数组的最佳方法是使用doctrine查询。
希望这可以帮助。干杯!
注意:如果您想要实体的数组表示的原因是将其转换为JSON以获得AJAX响应,我建议您查看此问答:How to encode Doctrine entities to JSON in Symfony 2.0 AJAX application?。我特别喜欢使用内置的JsonSerializable接口,这与我的回答相似。
由于Doctrine没有提供将实体转换为关联数组的方法,因此您必须自己完成。一种简单的方法是创建一个基类,该基类公开一个返回实体数组表示的函数。这可以通过让基类函数调用get_object_vars
来实现。此函数获取传入对象的可访问属性,并将它们作为关联数组返回。然后,只要创建一个要转换为数组的实体,就必须扩展此基类。
这是一个非常简单的例子:
abstract class ArrayExpressible {
public function toArray() {
return get_object_vars($this);
}
}
/** @Entity */
class User extends ArrayExpressible {
/** @Id @Column(type="integer") @GeneratedValue */
protected $id = 1; // initialized to 1 for testing
/** @Column(type="string") */
protected $username = 'abc';
/** @Column(type="string") */
protected $password = '123';
}
$user = new User();
print_r($user->toArray());
// Outputs: Array ( [id] => 1 [username] => abc [password] => 123 )
注意:您必须使实体的属性受到保护,以便基类可以使用get_object_vars()
访问它们
如果由于某种原因你不能从基类扩展(可能是因为你已经扩展了基类),你至少可以创建一个interface并确保你的实体实现接口。然后你必须在每个实体内部实现toArray
函数。
例:
interface ArrayExpressible {
public function toArray();
}
/** @Entity */
class User extends SomeBaseClass implements ArrayExpressible {
/** @Id @Column(type="integer") @GeneratedValue */
protected $id = 1; // initialized to 1 for testing
/** @Column(type="string") */
protected $username = 'abc';
/** @Column(type="string") */
protected $password = '123';
public function toArray() {
return get_object_vars($this);
// alternatively, you could do:
// return ['username' => $this->username, 'password' => '****']
}
}
$user = new User;
print_r($user->toArray());
// Outputs: Array ( [id] => 1 [username] => abc [password] => 123 )
几个月前我在我的存储库中创建了一个递归函数,它并不完美(比如,如果你有一个字段createdBy和updatedBy,它只会检索一个用户的值,因为使用$ aClassNamesDone提供了相当简单的递归保护),但它可能会有所帮助:
public function entityToArray($entity, &$aClassNamesDone=array(), $latestClassName="") {
$result = array();
if(is_null($entity)) {
return $result;
}
$className = get_class($entity);
// init with calling entity
if(empty($aClassNamesDone)) {
$aClassNamesDone[] =$className;
}
$uow = $this->getEntityManager()->getUnitOfWork();
$entityPersister = $uow->getEntityPersister($className);
$classMetadata = $entityPersister->getClassMetadata();
//DEPENDS ON DOCTRINE VERSION
//if(strstr($className, 'DoctrineProxies\\__CG__\\')){
if(strstr($className, 'Proxies\\__CG__\\')){
$uow->initializeObject($entity);
}
foreach ($uow->getOriginalEntityData($entity) as $field => $value) {
if (isset($classMetadata->associationMappings[$field])) {
$assoc = $classMetadata->associationMappings[$field];
if (isset($classMetadata->columnNames[$field])) {
$columnName = $classMetadata->columnNames[$field];
$result[$columnName] = $value;
}
// to avoid recursivity we can look for the owning side (gives similar results as Query::HYDRATE_ARRAY):
// elseif($assoc['isOwningSide']) { ...
// or we can track entities explored and avoid any duplicates (this will however ignore some fields pointing to the same entity class)
// for example: only one of createdBy, updatedBy will be kept
else if(!in_array($assoc['targetEntity'], $aClassNamesDone) || $assoc['targetEntity'] == $latestClassName) {
try {
if ($assoc['targetEntity'] != 'Timestamp') {
$aClassNamesDone[] = $assoc['targetEntity'];
$targetClass = $this->getEntityManager()->getClassMetadata($assoc['targetEntity']);
if (($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::MANY_TO_MANY) || ($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::ONE_TO_MANY)) {
$getterName = 'get' . ucfirst($assoc['fieldName']);
$entityChildren = $entity->$getterName();
foreach ($entityChildren as $oneChild) {
$result[$assoc['fieldName']][] = $this->getEntityManager()->getRepository($assoc['targetEntity'])->entityToArray($oneChild, $aClassNamesDone, $assoc['targetEntity']);
}
} else if (($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::ONE_TO_ONE) || ($assoc['type'] == \Doctrine\ORM\Mapping\ClassMetadata::MANY_TO_ONE)) {
$getterName = 'get' . ucfirst($assoc['fieldName']);
$entityChild = $entity->$getterName();
$result[$assoc['fieldName']] = $this->getEntityManager()->getRepository($assoc['targetEntity'])->entityToArray($entityChild, $aClassNamesDone, $assoc['targetEntity']);
}
}
} catch (\Exception $e) {
//var_dump('No entityToArray for ' . $assoc['targetEntity']);
throw ($e);
}
}
}
}
return $result;
}
我是Symfony的新手,但有一些工作(但很奇怪)的方式:
json_decode($ this-> container-> get('serializer') - > serialize($ entity,'json'))
你可以用它
$demo=array($demo);
