return message to user

Question

How can I change the message from "Log in" to "Welcome, User X". On the index.html page.

in index. html is like this

<p class="login"><b><a href="login.php">Faça o seu login!</a></b></p>

after the typed data is passed to the validator

<form class="form-signin" method="POST" action="valida.php">

and validates this if the login is successful :

if(isset($resultado)){
            $_SESSION['usuarioId'] = $resultado['id'];
            $_SESSION['usuarioNome'] = $resultado['nome'];
            //$_SESSION['usuarioNiveisAcessoId'] = $resultado['niveis_acesso_id'];
            $_SESSION['usuarioEmail'] = $resultado['email'];
                        if($_SESSION['usuarioId'] == $resultado['id']){
                header("Location: index.php");
            }

Initially your index should be . php to be able to make the change I will give as an example. In index you put an if to check if there is a Session if it exists it shows a div otherwise shows the login. Example:

index php.

if (isset($_SESSION['usuarioNome'])) {
   echo '<p class="exemplo"><b><a href="">Bem Vindo, Usuário '.$_SESSION['usuarioNome'].'</a></b></p>';
}
else{
   echo '<p class="login"><b><a href="login.php">Faça o seu login!</a></b></p>';
}
