Can Symfony Bundle be used in non-Symfony project (f.e. Zend)? - symfony

Can I reuse my Bundle created in Symfony in non-Symfony project, f.e. Zend? (Or I only can reuse Components?)
What about services from that Bundle?

A Symfony bundle can certainly be included in with other projects, via a composer.json & composer.lock file - it doesn't mean that there is any useful code to run within that bundle however.
If there is useful code as part of the bundle, then you can use it directly, but a Symfony Bundle is just a library that will usually include some Symfony-specific configuration.
Best practice for a bundle is to put any useful, common code, into a separate library (which could be used independently - such as what Symfony calls a 'Component'), and then enable that code (for example creating Symfony services, or configuration) with the bundle configuration.
There have been projects that are Symfony bundles, and also have the configurations for other frameworks as well, such as Silex, and also appropriate Laravel configurations within the same codebase.

Where to save your TWIG templates in Symfony framework

What is the best place to keep your TWIG template and why?
app/Resources/views folder
or
YourBundle/Resources/views
Traditionally, Symfony developers stored the application templates in
the Resources/views/ directory of each bundle. Then they used the
logical name to refer to them (e.g.
AcmeDemoBundle:Default:index.html.twig).
But for the templates used in your application, it's much more
convenient to store them in the app/Resources/views/ directory.
Syfmony Documentation
In Symfony 2, auto generated twig files were located in YourBundle/Resources/views
In Symfony 3, auto generated twig files are located in app/Resources/views
When developing your application, best place is YourBundle/Resources/views. It will be more consistent and probably it will be easier to maintain and eventually, decouple your bundle for installation in other projects.
I find app/Resources/views useful to override other bundle's templates, for example when creating Error pages http://symfony.com/doc/current/cookbook/controller/error_pages.html
It depends of your bundles architecture. The point is to be consistent with your current architecture.
From the official doc:
For most projects, you should store everything inside the AppBundle
If you use a main bundle structure (like a big AppBundle with many small domain bundles) then you probably want to centralize your templates in App or the ressources of your main Bundle.
But if you use a functionnal bundles (like EmailBundle, UserBundle, Invoice Bundle) then you probably want to ignore the symfony best practice and put the concerned twig in these bundles.

What is the difference between a bundle, component and a service in Symfony Framework?

What is a difference between bundle, component, service in Symfony? Thank you in advance
Bundle: A collection of code and other files written for use in a Symfony application.
http://symfony.com/doc/current/book/bundles.html
Component: Parts of the Framework that handle a certain task. They can also be used without the Framework.
http://symfony.com/doc/current/components/index.html
Service: Just a php class that provides certain functionality. It can be loaded through the Service Container which automatically handles dependencies.
http://symfony.com/doc/current/book/service_container.html
As I understand:
Components - standalone official libraries that can be used ether separately from Symfony framework or as a part of so called "Symfony-framework-skeleton". They are independent from other libraries.
Bundles - libraries that are additional to "core Symfony". They are dependent from Symfony components.
Services - libraries written by usual users for local projects that can be reused in different projects.
Service is any php class that has a relation with the dependency injection container, meaning that the container is able to manage it.
A component is a self contained entity that has usability even outside of a symfony based application, a library like PDO.
A bundle is symfony flex abstraction for providing simple modularity including configurations and automations.
So a bundle can be made out of a component.

About the default AppBundle in Symfony2

When creating a new SF2 project, the project contains an AppBundle by default. Should this be removed like the AcmeDemoBundle?
Symfony best practice
For most projects, you should store everything inside the AppBundle.
http://symfony.com/doc/current/best_practices/business-logic.html
Multiple bundles
I tend to create multiple bundles, e.g. I have these bundles in src/:
MyProjectEntityBundle
MyProjectBackendBundle
MyProjectHomePageBundle
And for reusable components I create a symfony bundle that I put into a git repository and load it via composer using satis. So for example I have some bundles in vendor/:
VendorCmsUtilBundle
VendorImageThumbnailBundle
"Domain Driven Design (DDD)"
I have yet to try this approach (I will soon):
http://williamdurand.fr/2013/08/07/ddd-with-symfony2-folder-structure-and-code-first/
As #Marcel Burkhard pointed out, the AppBundle is where you should put all your application logic according to Symfony best practices. Of course you can throw it away and build your own, but it's definitely not like the Acme Demo bundle.
I disagree with the strategy of splitting Entities and Frontend / Backend in different bundles.
I agree with the strategy of creating your own "utility" bundle(s) so that you can reuse your code in different projects via composer.

Where to place Application bundles?

I have an application written with Symfony and want to merge some small bundles as part of that app.
Regarding the quick Symfony2 bundle tour from Sonata, I need an ApplicationBundle.
quick Symfony2 bundle tour:
There are two types of bundles:
Application Bundle (AB),
Vendor Bundle (VB), that should not be modified inside a project.
The AB directory is where developers implement the project requirements,
An AB can overwrite almost everything from a VB, example: you can redefine a VB template at the AB level.
(Source)
Symfony documentation says about architecture:
The directory structure of a Symfony application is rather flexible,
but the recommended structure is as follows:
app/: the application configuration;
src/: the project's PHP code;
vendor/: the third-party dependencies;
web/: the web root directory
(Source)
But where shall I place it?
There are two possibilities:
app/Application (Sonata EasyExtends places ApplicationBundles here)
src
But what is the right one?
And why are there two possibilities?
The Symfony documentation doesn't cover ApplicationBundle.
Thanks for any hints.
The documentation say that :
Application Bundles (in 2 words, this is important) are stored in src/ directory.
Vendor Bundles are stored in vendor/directory (and came from your composer.json dependencies).
You can (and should) create many bundles for you application.

Create a bundle in vendors in Symfony2

I am trying to create a bundle in vendors in Symfony2.
MyBundle(MineUserBundle) needs to inherit other two bundle in vendors FOSUserBundle and HWIOAuthBundle.
How to get inherit both bundles properties, templates etc in Mybundle?
vendors
FOSUserBundle
HWIOAuthBundle
MineUserBundle
Here MineUserBundle needs to have all features of other two bundle.
How to get the process work?
Since you are using namespaces it does not mater into which folder you are going to deploy your Bundle. Just include use statements in your bundle with ones you need:
use Path\To\FOS\UserBundle;
use Path\ToHWIO\AuthBundle;
And you can extend whatever you need.
But if you really want to install your bundle to vendor directory, then you have to configure define it in your deps file.
[YourVendorYouBundle]
git=git#github.com:yourRepository/YourVendorYouBundle.git
target=/bundles/YourVendor/YouBundle
