The answer of your question is:

<?php
    session_start();
session_destroy();
?>
<meta charset="UTF-8">
<html>
<form method="GET" action="datos.php">
<?php
   if(isset($_GET['usuario'])){
    if(strcmp("ana",$_GET['usuario'])==0){
        if(strcmp("abc123.",$_GET['contraseña'])==0){
        $_SESSION['usuario']=$_GET['usuario'];
        }
        else{
         echo"
            <script>
                alert ('Usuario o contraseña incorrectos');
                window.location='login.php';
