{
$_SESSION["Authenticated"]= 1;
}
else {
$_SESSION["Authenticated"]= 0 ;
header("Location: index.html");
echo " incorrect login or password! ";

$_SESSION["Authenticated"]= 0 ; header("Location: index.html"); echo " login or password incorrect! ";


the header() function immediately redirects to the target, no lines of code will be executed after this function. If you want to display a message on index.php, we can imagine this: 

header("Location: index.php?Authentification=Error");


Just check on index.php if $_GET["Authentication"] is present and equals "Error", in this case, the credentials are incorrect.

I hope this help is important to you!
Have a good evening!
