By mvriel:

Both array and mixed[] would satisfy the PSR; though this might be mentioned in detail to prevent ambiguity.
I like the idea of being able to specify which types may be contained in an array if this is limited to a specific subset.
Though my vote would be on (int|string)[] as it feels more consistent with the other definitions to me
