Symfony2 - how to check if an object is a specific entity?

Question

symfony

How can such a check be done in symfony2?
There are such objects that come from the form:

Project\MediaBundle\Entity\File Object
(
    [id:Project\MediaBundle\Entity\File:private] => 
    [name:Project\MediaBundle\Entity\File:private] => Symfony\Component\HttpFoundation\File\UploadedFile Object
        (
            [test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 
            [originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 2014-04-09 00-25-51.JPG
            [mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => image/jpeg
            [size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 32347
            [error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0
            [pathName:SplFileInfo:private] => /tmp/phpBvJQSn
            [fileName:SplFileInfo:private] => phpBvJQSn
        )

    [size:Project\MediaBundle\Entity\File:private] => 
    [description:Project\MediaBundle\Entity\File:private] => описание картинки
    [type:Project\MediaBundle\Entity\File:private] => 
)

Project\CurBundle\Entity\Prop Object
(
    [id:Project\CurBundle\Entity\Prop:private] => 
    [value:Project\CurBundle\Entity\Prop:private] => первый текст
    [element:Project\CurBundle\Entity\Prop:private] => 
    [property:Project\CurBundle\Entity\Prop:private] => 
    [property_id:Project\CurBundle\Entity\Prop:private] => 
)

Those. two objects Project\MediaBundle\Entity\File and Project\CurBundle\Entity\Prop . What these objects are is not known in advance. They can be any (from a certain set).
Is it possible to check something like:

if (isEntityObject('Project\MediaBundle\Entity\File')) {
    echo 'Это объект из нашего проекта типа "файл"';
}
if (isEntityObject('Project\CurBundle\Entity\Prop')) {
    echo 'Это объект из нашего проекта типа "свойство"';
}

Or it can be done simply by means of php, something I don't know :(

If your class is under the namespace Entity, then it should be Entity, if it is not, then you need to take these classes out of this namespace.
Entity in the context of Symfony is an ordinary class (we do not take into account the fact that when it is selected from the base, it turns into a proxy). If you need to check if a variable is a class instance, then use instanceof.
ps storing UploadedFile in Entity is not the best solution.
