Original Pull Request: https://github.com/doctrine/orm/pull/9535

State: closed
Merged: Yes

In PHP 8, classes that implement the __toString() method automagically implement a new interface called Stringable. This means that we can rewrite method_exists() checks for __toString() to instanceof checks.

We could also consider announcing the Stringable interface explicitly on our own classes with a __toString() method. But that would be pure documentation because, as already mentioned, PHP will add the interface whether we announce it or not.
