Save, I buggy here trying to get ajax to fetch data from a JSON and I need a class / help to understand how I pull the values from an array of objects (I think that's it). I have the following code, it's kind of confusing, but my goal is to do the following:

Field "areaatu_02" selected?
Yes: Then it returns as "select" from the html with the values of the "own_title" that are in JSON

But I've never worked with a more complex JSON structure, I've been working with a few more simple ones: {"name": "Rafael Eduardo"}

Now I'm encountering an array inside the array and this is bugging my head a lot ...

Was my question too confusing? here is the code I tried to create:

json.php

 $obj = ('{
    "area_atuacao": [{
        "areaatu_02": [{
            "portador_titulo": [
                "AMB",
                "RESIDÊNCIA MÉDICA"
                ],
            "possui_titulo": [
                "MEDICINA PREVENTIVA E SOCIAL",
                "ADMINISTRACAO EM SAUDE" 
            ]
            }],
        "areaatu_04": [{
            "portador_titulo": [
                "AMB",
                "RESIDÊNCIA MÉDICA"
                ],
            "possui_titulo": [
            "ALERGIA E IMUNOLOGIA",
            "PEDIATRIA"
            ]
            }],
        "areaatu_07": [{
            "portador_titulo": [
                "AMB",
                "RESIDÊNCIA MÉDICA"
                ],
            "possui_titulo": [
            "ANGIOLOGIA",
            "CIRURGIA VASCULAR",
            "RADIOLOGIA"
            ]
            }]
    }]

}
');
// converto em um Array
    $myARRAY = json_decode($obj);
//coloco na tela
    echo json_encode($myARRAY);
    ?>

To transform JSON into Array, you need to indicate true within json_decode

Looking like this:

$myARRAY = json_decode($obj, true);

And to get the data in PHP just try:

$myARRAY['area_atuacao']['areaatu_04']['...'];

Here's a solution, which involves changing the structure of JSON (since you said that this was possible). This way it gets simpler, if you do not need to complicate it better.

JSON framework:

{
    "areaatu_02": {
        "portador_titulo": [
            "AMB",
            "RESIDÊNCIA MÉDICA"
        ],
        "possui_titulo": [
            "MEDICINA PREVENTIVA E SOCIAL",
            "ADMINISTRACAO EM SAUDE"
        ]
    },
    "areaatu_04": {
        "portador_titulo": [
            "AMB",
            "RESIDÊNCIA MÉDICA"
        ],
        "possui_titulo": [
            "ALERGIA E IMUNOLOGIA",
            "PEDIATRIA"
        ]
    },
    "areaatu_07": {
        "portador_titulo": [
            "AMB",
            "RESIDÊNCIA MÉDICA"
        ],
        "possui_titulo": [
            "ANGIOLOGIA",
            "CIRURGIA VASCULAR",
            "RADIOLOGIA"
        ]
    }
}

jQuery:

function areaAtuFun() {

    var opFormValue = $('#areaAtu').val();
    var tituloSelect = $('#PossueAreaAtu');
    var opFormUrl = "json.php?data=area_atuacao." + opFormValue;

    $.ajax({
        dataType: "json",
        url: opFormUrl,
        method: "GET",
        success: function(retorno) {
            var valores = retorno[opFormValue].possui_titulo;
            if (valores.length == 0) return alert('Houve um erro com os dados! 0');
            $('#PossueAreaAtu option').remove(); // apagar as options existentes
            valores.forEach(function(string) {
                $('<option/>', {
                    value: string,
                    html: string
                }).appendTo(tituloSelect);
            });
        },
        error: function() {
            alert("Falha de conexão, tente novamente. 1")
        }
    })
}
