Validate array based on a schema

[szepeviktor]

What is this feature about (expected vs actual behaviour)?

Provide a schema a check validity of/fix an array.

@voku Do you happen to know a package that does this? Do you plan to implement it?

[voku]

Sounds interesting, what kind of schema did you think of?

[szepeviktor]

I'm not ready with the answer! JSON schema seems to be popular but it is complex. As far as I can see it needs only key type, value type and is_required. ...for trees and multidimensional arrays too

[rcsofttech85]

are you talking about json validation?

[szepeviktor]

Yes. But not exclusively.

[rcsofttech85]

php has a json_validate function in its latest version ..fixing things for minor version does not make sense i guess..

[voku]

@rcsofttech85 json_validate only validates the JSON, not the data in the JSON

@szepeviktor It's already possible to validate / extract multidimensional data from JSON e.g.
