from an associative and multidimensional Array in PHP i get this object by json_encode():
{"2047":
{"f1a":
{"val":["7","7","6","1","6","6"],
"cnt":6,
"sum":33,
"avg":5.5
},
{"f2a":
{"val":["7","6","5","7","5","3","5","7","6","7"],
"cnt":10,
"sum":58,
"avg":5.8
},
"2048": ...
}
and i want to read the value of avg of f2a and 2047.
