Storing value fetched from PHP into UE4 Array

I am working on a specific UI for my project which contains many fields.

I am fetching my data from PHP using vaREST plugin.

Problem : Is there a way to fetch this value from PHP and storing it in UE4 arrays so that i can use it evenly inside my EventGraph.
Is this even possible ?

Any help or push in right direction is appreciated.

What exactly is the problem? You can store the fetched data any way you like.
