php - return single array from json by passing a value

I have a json that I need to filter a specific key and
value from

the following
json

{
"5": {
 "Owner":
            "94EAC",
 "Record":"0121ln"
},
"15": {
 "Owner":
            "009AC",
 "Record":"0120Pc"
},
"1": {
 "Owner":
            "00G11A",
 "Record":"000lPcn"
},
"199": {

            "Owner": "00G1y9",
 "Record":"01211cn"
},
"33":
            {
 "Owner": "001AC",

            "Record":"0121n"
}

}

I
would like to be able to pass the first int and get back array for that
number.
For example if I pass 15 I get

 {
 "Owner": "009AC",

            "Record":"0120Pc"
}

I
tried foreach loop but cannot set specific value for the first
int

If I assign $data =
            json

then $date[15] didn't
work
$data->15 also didn't work

I did also
use the json decode and was able to print an array but wasn't able to get a single
value
Any help would be great, I did spend all day and still cannot get an
answer.
Thank you
