Combining PHP 8 attributes with old style annotations

[jelovac]

Can we combine attributes and old style annotations when working with entities which belong to the same namespace? I am involved in refactoring and migrating some legacy codebase to Symfony 5 and would like to gradually replace the old style annotations in entities with PHP 8 attributes.

According to some discussion on StackOverflow in order to enable PHP 8 Attributes support in Symfony 5 we had to change the mapping type from "annotation" to "attribute" like in the example below:

# config/packages/doctrine.yaml

doctrine:
  orm:
    mappings:
        App:
            type: attribute

So according to the above example will old style annotations be ignored or parsed as well?

They will be ignored. It might be possible to define two mappings, App2 and then overwrite the relevant sub-option to set the namespace as App for the second entry. You might need to dig into bin/conosle config:dump-reference doctrine, DoctrineExtension and AbstractDoctrineExtension to find out exactly how.

I see, thanks for clarifying. Will check it.
