How to parse multidimensional json array in php?

Question

PHP

Good afternoon, I receive a json array of the following form via rest api.

data {
  calls
    {
    "id": "7e734dc1-544d-4f04-8ccc-8bd5b197a88c",
    "caller": 
    {
        "name": "u2 u2",
        "extension": "101"
    },
    "called": 
    [
        {
            "isConnected": true,
            "name": "akmightycall4 akmightycall4",
            "extension": "100"
        },
        {
            "isConnected": false,
            "name": "u3 u3",
            "extension": "102",
            "phone": "[phone]"
        }
    ],
    "businessNumber": "[phone]",
    "dateTimeUtc": "2018-06-05T13:38:29.522Z",
    "duration": "23066",
    "direction": "Outgoing",
    "callStatus": "Connected",
    "callRecord": 
    {
        "fileName": "records/T1U9Y5b197a88c.wav",
           "uri": "http://localhost/u2.wav?recordid=fdaVn2YWttaWdodHljYWxGV20"
    }
}
}

With the help of the following code, I can pull out the values ​​that come after calls of type id:

$json = json_decode($result, true);

foreach($json['data']['calls'] as $item) {
print $item['id'];
print '<br>';
}

But I don't understand how I can get values ​​from called and caller. Explain, please.

Answer 1

var_dump($item)...
