Capture $.getJson value is coming Undefined

Question

I’m trying to assemble a table from a JSON that I receive from a page php, meanwhile when I do the append the captured value appears as Undefined.

$.getJSON("getEventoCategoria.php", {ID_EVT_Evento: ID},function (data) {
                var tabledata = "";
                console.log(data);
                console.log(data[0].DSC_Nome);
                $.each(data, function (index, item) {
                    console.log(item.DSC_Nome);
                    console.log(item.VLR_Inscricao);
                    
                    $('#conteudoTabelaCategoria')
                            .append(
                                    "<tr>" +
                                    "<td>" + item.DSC_Nome + "</td>" +
                                    "<td>" + item.VLR_Inscricao + "</td>" +
                                    "<td>" + item.DT_Inicio_Valor + "</td>" +
                                    "<td>" + item.DT_Fim_Valor + "</td>" +
                                    "</tr>"
                                    );
                });
            });

in php file:

<?php

$ID_EVT_Evento = $_REQUEST['ID_EVT_Evento'];
require_once './actions/aEvt_Evento_Categoria.php';

$EventoCategoria = new aEvt_Evento_Categoria();

$arr[] = $EventoCategoria->selectCategoriasDoEvento($ID_EVT_Evento);

echo json_encode($arr);

when I do a direct get by the url it displays me the following JSON:

[[{"ID_Evento_Categoria":"528c234df006558ae470fa0ccabe7892","DSC_Nome":"Categoria 01","VLR_Inscricao":"100.00","DT_Inicio_Valor":"2015-01-01","DT_Fim_Valor":"2015-12-31","ID_EVT_Evento":"528c234df006558ae470fa0ccabe7892"}]]

I’ve put some debug logs in. Someone’s been through this trouble?

Solved. I only removed the "[]" in the "arr" variable in the php file.
