How to use existing instance without creating new connection to database?

Before I used DriverManager::getConnection(['pdo' => PDO_INSTANCE]); but it does not work anymore.

Using 'pdo' option results in mysql error No such file or directory

For now I've used own driver, but it should not be a solution…I think

You cannot. In order to share the same PDO instance between DBAL and other components, initialize the connection in DBAL and access it using Connection::getNativeConnection().

Sure. If you have an idea how to improve the developer experience in your case, please submit a PR to the DBAL repository and we consider it. 🙂

We created a library that relies on the ability to pass an existing PDO connection into it, and internally, the library uses this PDO connection with Doctrine in the same way @jakublabno describes. When trying to upgrade to Doctrine 3.x, I ran into this issue, which led me here.

To be clear, we don't want to get the native connection from Doctrine. We want to give Doctrine an existing native connection that it can use with the ORM.

From your answer, it sounds like this is no longer possible?

You can build a driver yourself that does this. Afaik Laravel does that so the code is out there somewhere

Yes, I've built my own driver, it's very simple to achieve that 🙂

Okay. That's what I've done, then.
