Validators: support for types int[] and string[]

[JanTvrdik]

How do you feel about supporting either specifically int[] and string[] (defined as list where all values are of given type)?

Or we can generally support anything[], but I don't think that's necessary.

[JanTvrdik]

Alternative approach: add Validators::isListOfType($value, $type) or add new optional parameter $type to current isList method. But then you cannot simple use Validators::assert(). You can however use PHP built-in assert().

Do you have any use real cases for this?

[JanTvrdik]

Yes, of couse. For example list of ids in query param.

[TomasVotruba]

Could you prepare PR for this?

[JanTvrdik]

It's undecided how this should be implemented (see the first two comments). The implementation itself is likely trivial.

[TomasVotruba]

Validators::isListOfType($value, $type) seems much clear to me and describes the intention better.

And what if it is not a list, but a map (i.e. key => value array)?

[JanTvrdik]

@dg Then it will return FALSE =)

Would you prefer more general approach, e.g. array<string, bool> or vector<string>?

In PHP is more understandable anything[] than array<anything>
