How to access data sent by PUT (ajax) in php?

Question

I am creating an application in REST format in which my front-end requests a PUT (By ajax) to the back-end. No request I am sending the new information for update, but I am not able to access this information in PHP, I did a research on the subject, I know that PHP has not defined the super global $_PUT as the $_POST. I came across people searching the data from php://input but when I perform the procedure parse_str(file_get_contents('php://input'), $teste); the return does not come in Array. Has anyone ever gone through this and can give me a light? Note: I am not using backend frameworks.

PHP code I have a file of routes that calls the method.

    public static function update($param){
        parse_str(file_get_contents('php://input'), $teste);
        echo "<pre>";
        var_dump($teste);
        exit;

    }

Javascript code

Method for making PUT calls

function putAjax(uri, data, callback) {
    $.ajax({
        url: uri,
        type: "PUT",
        dataType: "json",
        data: data,
        cache: false,
        contentType: false,
        processData: false
    }).done(function (data) {
        if (callback) {
            for (var i = 0; i < callback.length; i++) {
                callback[i](data);
            }
        }
    }).fail(function () {
        fechaLoading();
        return false;
    });
}

Method that is calling the putAjax

function updateServidores(form) {

    var verificaRetorno = function (data) {
        if (data.status) {
            if (data.status === true) {
                servidor.splice(indiceUpdateServidores, 1);
                servidor.push(data.data[0]);
                montaGrid(".tableServidores");
                abreTela("#viewServidores");

                notify("success", "Sucesso!", "Item alterado com sucesso!");

            }else {
                notify("error", "Erro!", data.erro.message);
            }

            indiceUpdateServidores = null;
        }
    };

    after = [];
    after.push(verificaRetorno);

    var formData = new FormData(form);
    putAjax(url + "servidor/" + servidor[indiceUpdateServidores].ID_SERVIDORES, formData, after);
}

Exit from file_get_contents('php://input'):

If you are receiving the data in the backend in JSON format, you should use the function json_decode and not parse_str:

public static function update($param){
    $teste = json_decode(file_get_contents('php://input'));
    echo "<pre>";
    var_dump($teste);
    exit;
}

Thus the variable $teste will contain an object or array depending on what was sent

You can use $teste = json_decode(file_get_contents('php://input'), true); so that objects are transformed into associative arrays
