Excluding certain links from the menu

[prtst33]

How can I exclude certain links from the menu?
Let's say I have the following pages, home, blog, news, contact.
How can I keep in the main menu only links to home, blog, contact?

Original nav.php, where the menu is dynamically constructed:

<nav class="navigation">
  <ul>
    <li>
      <a<?= $site->is('home') ? ' class="current"' : ""; ?> href="<?= $url; ?>">
        <?= i('Home'); ?>
      </a>
    </li>
    <?php foreach ($links as $link): ?>
      <li>
        <a<?= $link->current ? ' class="current"' : ""; ?> href="<?= $link->link ?: $link->url; ?>">
          <?= $link->title; ?>
        </a>
      </li>

    <?php endforeach; ?>

  </ul>
</nav>

I've found two solutions that work, but i'm not sure if that's the right way to do it.
First option:

<nav class="navigation">
<ul>
    <?php

    $navLinks = [
        $url . '/home' => 'Home',
        $url . '/blog' => 'Blog',
        $url . '/contact' => 'Contact',
    ];

    $currentUrl = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    $currentUrl = preg_replace('#([^:])//+#', '$1/', $currentUrl);

    foreach ($navLinks as $url => $name) {
        $url = preg_replace('#([^:])//+#', '$1/', $url);
        $isCurrent = strpos($currentUrl, $url) === 0 ? ' class="current"' : '';

        echo "<li$isCurrent><a href=\"$url\">$name</a></li>";
    }
    ?>
</ul>
</nav>

Second option:

<nav class="navigation">

    <ul>
    <li><a href="<?= $url; ?>/home">Home</a></li>
    <li><a href="<?= $url; ?>/blog">Blog</a></li>
    <li><a href="<?= $url; ?>/contact">Contact</a></li>
    </ul>
    
</nav>

Is there a better way to do this? I don't know php.

You can add custom property to a page to tell the loop that certain item need to be excluded. This is common example:

---
title: Exclude Me
description: Exclude this page from menu.
skip: true
...

Lorem ipsum dolor sit amet.

Then in the navigation loop (the second line):

<?php foreach ($links as $link): ?>
  <?php if ($link->skip) continue; ?>
  <li>
    <a href="<?= $link->url; ?>">
      <?= $link->title; ?>
    </a>
  </li>
<?php endforeach; ?>
