From:

it all comes down to autoload magic. The autoload magic assumes a certain directory structure, that is (among other things) defined in composer.json. It essentially says:

namespace AppBundle\... is in directory src/AppBundle/...

and every class AppBundle\Something\Else is therefore located in src/AppBundle/Something/Else.php

now, symfony starts to load the service that is supposed to handle an event (due to your configuration) AppBundle\Event\MaintenanceListener, which it tries to instantiate, which leads to the auto loader loading the file src/AppBundle/Event/MaintenanceListener.php which only contains the class MListener/MListener.

Since auto-loading is a bit hacky, usually, it will try other approaches / definitions and possibly try to read that file again and it'll then fail to re-declare the MListener/MListener class, since it already exists.

Just to be explicit about this: These approaches work very well if standards are followed (specifically PSR-4 in this case), which bind the directory structure to namespace structure. If you put something in a file, that - according to PSR-4 - doesn't belong there, you gonna get problems, like the one you got.

The fix is easy and obvious: namespace is the directory (with backslash instead of whatever directory separator your OS has), filename is the classname (without .php obviously). So either, rename your file to src/MListener/MListener.php and adapt the services.yaml accordingly: MListener\Mlistener: ... or you rename your namespace and class in that file to AppBundle\Event and MaintenanceListener respectively.

It is showing you have the mongo extension, which is apparently deprecated and should be mongodb. Check this out from the mongo docs:

The mongo extension available from PECL is an older, legacy driver for PHP 5.x. The mongo extension is no longer maintained and new projects are advised to use the mongodb extension and PHP library. A community-developed Mongo PHP Adapter project implements the legacy mongo extension’s API using the new mongodb extension and PHP library, which may be useful for those wishing to migrate existing applications.

Installation for mongodb extension per the PHP docs can be found here. It basically says to do this with PECL:

So yeah, basically answered my own question. I got my own solution for this kind of approach. I have to change my eventlistener for "Edit Form".

As I understood when you query database by repository you get PersistentCollection and when your working with your entities you get ArrayCollection

I have changed the \Doctrine\Common\Collections\ArrayCollection $sector as array $sector in $formModify function. also I have changed in PRE_SET_DATA and POST_SUBMIT Events too.

Below is the full code of changed event listener.
