I am trying again to create a table with the entered data using

$_SESSION

    <?php session_start() ?>

        <fieldset>
            <legend>Lista de contatos</legend>
            <label for="name">
                Nome:
                <input type="text" name="nome" id="name">
            </label><br>
            <label for="tel">

            </label>
            <input type="submit" value="Cadastrar">
        </fieldset>
    </form>

    <?php 
           $contatos = [];

            if (array_key_exists('nome', $_GET)) {
                $_SESSION[contatos]['nome'][] = $_GET['nome'];
             }
            if (array_key_exists('tel', $_GET)) {
                $_SESSION[contatos]['tel'][] = $_GET['tel'];
            }
            if (array_key_exists('email',$_GET)) {
                $_SESSION[contatos]['email'][] = $_GET['email'];
            }
            $contatos = [];
            if (array_key_exists('contatos',$_SESSION)) {
                $contatos = $_SESSION['contatos'];
            }
    ?>

    <table border="1">
        <tr>
            <th>Nome</th>
            <th>telefone</th>
            <th>E-mail</th>
        </tr>
        <?php foreach($contatos as $contato=>$value) : ?>

        </tr> 
            <?php for($i=0; $i < count($value); $i++): ?>

                    <td><?php echo $value[$i]; ?></td>

            <?php endfor; ?>
        </tr>              

        <?php endforeach; ?>

    </table>
</body>

</html>

is storing normal, but is not following the order of the table.

See message in $_SESSION[contatos] the contatos is not set. If it is to be a variable, it lacked the $ in front, but does it make sense to have an empty array as the session key? If it was supposed to be string, the quotes were missing

I removed the empty contacts, but still it is not following the order of the table; It is getting all in one column.
