Fixed with array<int, mixed>.

For note: the behaviour seems different with other rule that uses syntax: mixed[] over array<int, mixed>

The improvement next maybe if it only int key, should not use array<int, type> syntax, use direct type[] instead for consistency.

All checks have passed 🎉 @TomasVotruba I am merging it ;)

Why return mixed[] for an empty array over array{}?

The array is empty and with array{} you say that it is.

I just know that it can use empty @return array{}

Let see if it can be improved next to that

The array key can never be mixed, at most it should be array-key

I created PR to use array shape empty on

• [TypeDeclarationDocblocks] use empty array shape array{} for returns empty array on DocblockReturnArrayFromDirectArrayInstanceRector #7289
