Display correctly RELATIONSHIP

Hello,
In a dashboard that I prepare, I need to retrieve the information "RELATIONSHIP"

When I do: $ profile-> getFieldValue ('RELATIONSHIP')

This displays (For example)
{ "Target": [ "984"], "targetRelation": [ "984"], "type": "relationship"}

I would like to display it correctly.

I thought of directly drawing this information from the table "social_relationship_status", but jp teach that I complicate and that there is certainly a much simpler way.

Also when I do: $ profile-> getFieldValue ('BIRTHDAY') ;, I would like to display that day and month, how do I format this display?

Best regards.

Eric
