Good evening. This is snippet of avro schema field that I need to
build data for and populate in php *{"name": "meta__kvpairs", "type":
[ "null", { "type": "map", "values": ["null", "string"] } ] }*.Would appreciate if someone gives me an example of how data would look in php to satisfy meta__kvpairs avro rule so that it can be serialized without exception. Thanks so much.
