Yeah, you can work it out with Ajax / jQuery:

Home page (index php.):

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <script type="text/javascript" src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
</head>
<body>
    <div id="DivSaida">
        <!-- VALOR DA VARIÁVEL SERÁ MOSTRADO AQUI -->
        <?php require_once("minhapagina.php"); ?>
    </div>
</body>
<script type="text/javascript">
    $(document).ready(function(){

        minhaUrl = "minhapagina.php"; // CAMINHO DA PÁGINA COM O ECHO

        setInterval(function(){

            $.ajax({
                url: minhaUrl,
                success: function( response ) {
                    $('#DivSaida').html( response );
                }
            });

        }, 5000); // TEMPO PARA ATUALIZAR EM MS (milissegundos)

    });
</script>
</html>

Page with the echo of the variable (php.):

<?php

$file = file_get_contents('json.php');
$decode = json_decode($file, true);
$ultimo = end($decode);
$variavel = $ultimo['latitude'];
echo $variavel; //MOSTRA EXATAMENTE ESSE VALOR NA PÁGINA PRINCIPAL

?>

I didn’t change your exit variable, just gave a echo! I left some comments in the code, which I found interesting you change.
