Answer 1

I am assuming you are using a session to check whether user logged in or not. If not, create a session variable and set once logged in. Clear the session variable on log out. So you can check

if(isset($_SESSION['logged_in'])){
//your logout link
}else{
//your login link
}

 <?php 
        if ($signout) 
        { 
            echo "<li><a href=logout.php >Logout</a></li>";
        } 
        else 
        { 
            echo "<li><a href=register.php >Register</a></li>";
            echo "<li><a href=login.php >Login</a></li>";
        } 
?>

Try this.

You need to set a variable $logged_user to identify whether the user is logged in or not

<header class="group">
<nav class="group">         
    <ul>
        <?php if ($logged_user) { ?>
            <li><a href="logout.php" title="">Logout</a></li>             
        <?php } else { ?>
            <li><a href="register.php" title="">Register</a></li>
            <li><a href="login.php" title="">Login</a></li>   

        <?php } ?>
    </ul>
</nav>

<?php 
    if(isset($_SESSION['user_id'])) { 
        echo "<form method='POST' action='".userLogout()."'>";  ?>
            <li><button type="submit" name="userlogout" id="logout-button" class="button-logout">LOGOUT</button></li>

<?php } else { ?>
        <li><a href="login">LOGIN</a></li>
    </form>
<?php }
?>
