I note that the array element for "protocol" seemingly has no value, being reported as:

["protocol"]=> int(3)

whereas the array element for e.g. "server" is reported as (in my particular case):

["server"]=> string(5) "10.12"

A call to json_encode() however gives:

"protocol":3 and "server":"10.12"
