How can i write an JSON file with PHP which looks like this (nested JSON structure)?

I want to write an "nested" JSON structure with PHP Have a look below how the result should look like:

(Manually written -can read in JS without errors :) )


{
    "general": {
        "language": "English",
        "workingmode": "Normal"
    },
    "scene": [{
          "id": 0,
          "calendar_event": "urlaub",
          "element": [
              {
              "device": "boiler1",
              "active_state": "nothing",
              "hybernation_state": "off",
              "calendar_name": "roomlink4"
              },
              {
              "device": "boiler1",
              "active_state": "on",
              "hybernation_state": "off",
              "calendar_name": "roomlink4"
              }
          ]
        },
        {
          "id": 1,
          "calendar_event": "urlaub",
          "element": [
              {
              "device": "boiler1",
              "active_state": "on",
              "hybernation_state": "off",
              "calendar_name": "roomlink4"
              },
              {
              "device": "boiler1",
              "active_state": "on",
              "hybernation_state": "off",
              "calendar_name": "roomlink4"
              }
          ]
        }
    ]
}

This is the code I have so far: 


$knxGenSet = (object) [
    'general' => (object) [],
    'scene' => []

    //Now i Struggle with this part, i cannot accomplish it to add "element" so that it is nested inside of "scene"
];

//creating structure for "general"
$knxGenSet->general->language = $_POST["langsetts"];
$knxGenSet->general->workingmode = $_POST["wmodesetts"];

//second part which i struggle with
  $knxGenSet->scene[] = (object) [
      //creating structure for "scene"
      'id' => 0,
      'calendar_event' => "anything"
      //Struggle: cannot get it right to add "element"-array which consists of 4 more String to the structure
  ];

I did manage to add the "general" tab and an part of "scene" but what i didn't manage to do is to add the part of "element"-array to the "scene"

btw i can allready read this json format with JS

Thanks in advance (kind of newb on json territory! :()

you were missing some minor key points 

$knxGenSet = (object) [
    'general' => (object) ["language" => $_POST["langsetts"], 
    "workingmode" => $_POST["wmodesetts"]
]
];

for($j=0; $j<2; $j++) {
    $scene = (object) [
        'id' => $j,
        'calendar_event' => $_POST["calendarevent" . $j]
    ];

    for($ii=0; $ii<2; $ii++) {
        $scene->element[] = (object) [
            "device" => "boiler".$ii,
            "active_state"=> "on",
            "hybernation_state"=> "off",
            "calendar_name"=> "roomlink4"
         ];
    }
    $knxGenSet->scene[] = $scene;
}

print json_encode($knxGenSet);

output

{
    "general": {
        "language": null,
        "workingmode": null
    },
    "scene": [{
        "id": 0,
        "calendar_event": null,
        "element": [{
            "device": "boiler0",
            "active_state": "on",
            "hybernation_state": "off",
            "calendar_name": "roomlink4"
        }, {
            "device": "boiler1",
            "active_state": "on",
            "hybernation_state": "off",
            "calendar_name": "roomlink4"
        }]
    }, {
        "id": 1,
        "calendar_event": null,
        "element": [{
            "device": "boiler0",
            "active_state": "on",
            "hybernation_state": "off",
            "calendar_name": "roomlink4"
        }, {
            "device": "boiler1",
            "active_state": "on",
            "hybernation_state": "off",
            "calendar_name": "roomlink4"
        }]
    }]
}
