Sessions on a login system

I made a login system in PHP where, after authentication, I go back to the page index.php.

So far so good, the problem is that when I redirect the user to the index.php again, it asks me for login data.

Someone knows what I’m doing wrong?

Follow the page index.php:

<?php
if(!isset($_SESSION)){ 
   session_start(); 
} 

if(!isset($_SESSION["$Email"])){
   echo 'todos os forms de login';
} 
else{
   echo 'todo o site';
}

And here is the authentication function:

public function autenticacao($Email, $Senha){
    $oConexao = new conexaoclass();
    $oConexao -> abrirConexao();
    $sql = "SELECT * FROM Professores 
            WHERE Email = '$Email' AND Senha = '$Senha'";

    $this -> resultado = mysql_query ($sql, $oConexao -> getConn());

    $rows = mysql_num_rows($this -> resultado);

    if ($rows > 0) {
        session_start();
        $_SESSION["$Email"] = $Email;
        $_SESSION["$Senha"] = $Senha;

        echo "Login realizado com sucesso! <br> Aguarde, você será redirecionado...";
        echo "<script>login()</script>";
    }
    else{
        echo "Login inválido!!! Dados incorretos! <br> Aguarde, você será redirecionado...";
        echo "<script>loginFail()</script>";
    }
}

    Instead of $_SESSION['$email'] use $_SESSION['email'] = $email.

    Maybe it’s not the focus of the question. But always try to avoid keeping a pure password in the bank. Try to store the encrypted password and at the time of authentication only compare the encrypted passwords. Security issue.

In part $_SESSION["$Email"] take off the $.

You are telling php that you want to use the contents of the variable as the session index $Email, which is not defined in the vector.

Preferably, when using associative arrays, use single quotes '.

Do this with the other similar occurrences in your code.
