Answer 1

Just add this else code block after if

<? else{ ?>
    <a href="login.php">Login</a>
<? } ?>

So, you code should look like this:

   <?
  if (isset($_SESSION['user_id'])) {?>
    <div class="myaccount">
    <p><strong>My Account</strong></p>
    <a href="myaccount.php">My Account</a><br>
    <a href="mysettings.php">Settings</a><br>
    <a href="logout.php">Logout </a>
    <p>You can add more links here for users</p></div>
  <? } ?>         <!-- line x -->
  <? else{ ?>     <!-- line y -->
    <a href="login.php">Login</a>
  <? } ?>

line x and y can be combined to this:

<? } else { ?>

EDIT:

Using the x and y lines combined, your code should look like this:

   <?
  if (isset($_SESSION['user_id'])) {?>
    <div class="myaccount">
    <p><strong>My Account</strong></p>
    <a href="myaccount.php">My Account</a><br>
    <a href="mysettings.php">Settings</a><br>
    <a href="logout.php">Logout </a>
    <p>You can add more links here for users</p></div>
  <? } else { ?>
    <a href="login.php">Login</a>
  <? } ?>
