PHP Array to JSON in this format as requested

I need to make a php array from a mysql request, and in a loop pass into a JSON.

My sql is like this below:

$arDados = array();
$result = $conexao->sql("SELECT * FROM sys_fabrica WHERE fl_ativo = 1 ORDER BY tl_fabrica");    
while($dados = mysql_fetch_array($result)) {
    $cd_fabrica = $dados['cd_fabrica'];
    $tl_fabrica = $dados['tl_fabrica'];
    $tl_razao = $dados['tl_razao'];
    
    $totalValorAno = retornaValorTotalAnoPecas($ano, $cd_fabrica);
    $metaFaturamentoAnual = retornaMetaFaturamentoAnual($ano, $cd_fabrica);
    $percentMetaFaturamentoAnual = number_format(($totalValorAno * 100) / $metaFaturamentoAnual, 0, ',', '.');
    if($percentMetaFaturamentoAnual < 50){
        $classeProgressFaturamento = "danger";
    } else if($percentMetaFaturamentoAnual < 90){
        $classeProgressFaturamento = "warning";
    } else {
        $classeProgressFaturamento = "success";
    }
    
    $arrayDados[]      = array(
        fabrica => $tl_fabrica, 
        value => abs($percentMetaFaturamentoAnual),
        full => 100,
        columnSettings => array(
            fillOpacity => 1,
            fill => "am5.color(KTUtil.getCssVariableValue('--bs-$classeProgressFaturamento'))";
        )
    ); 
}
$arrayDados = json_encode($arrayDados, JSON_PRETTY_PRINT);
echo $arrayDados;

And this is the data I need to pass into thee graphics (AMCharts).

// Data
                var data = [
                    {
                        fabrica: "Fabrica",
                        value: 80,
                        full: 100,
                        columnSettings: {
                            fillOpacity: 1,
                            fill: am5.color(KTUtil.getCssVariableValue('--bs-info')),
                        },
                    }
                ];
