Keep field data as selected

Navigation

I have the following code: 

    // Dentro do arquivo somar.js
    <script>
    function soma(){
    if(document.getElementById('QtdAcomodacaoSingle').options[0].selected == false){
     TextoAcos = (QtdAco == 1)?("passageiro"):("passageiros");           
                 document.getElementById("alterar").innerHTML = QtdAcos + " " + TextoAcos;
    ......
    }
    }
    </script>

    // Página index.php
    <select name="QtdAcomodacaoS" id="QtdAcomodacaoSingle" class="form-control" style="width:130px" onchange="soma()">
    <option value='1'>1</option>
    <option value='2'>2</option>
    <option value='3'>3</option>
    </option>
<div id="alterar" style="text-align: center; ">---</div>

When you select the number of accommodations, the selected number in the change div automatically appears. So far so good. However, I want to keep the information on the form that has been registered. I get it in all fields, but how would I make this effect of selecting a number appear in the div change, work after bringing those results in php? I tried this way: 

<?php if($_SESSION['Ativo'] == false){ ?>
       <div id="alterar" style="text-align: center; ">---</div>
       <?php }else{ 
              echo $visualizarS->QtdPax; 
            } 
       ?>

When I do this, the change div gets stuck inside the session validation.

Try this: 

<div id="alterar" style="text-align: center; ">
    <?php 
    echo ($_SESSION['Ativo'] == false) ? '---' : $visualizarS->QtdPax; 
    ?>
</div>
