Basic Sitemap

This will show you how to create the most basic XML sitemap.

[!!] Only the loc argument is required, the others are optional.

// Sitemap instance.
$sitemap = new Sitemap;

// New basic sitemap.
$url = new Sitemap_URL;

// Set arguments.
$url->set_loc('http://google.com')
    ->set_last_mod(1276800492)
    ->set_change_frequency('daily')
    ->set_priority(1);

// Add it to sitemap.
$sitemap->add($url);

// Render the output.
$output = $sitemap->render();

// __toString is also supported.
echo $sitemap;

Output

The above example should output the following

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
	<url>
		<loc>http://google.com</loc>
		<lastmod>2010-06-17T19:48:12+01:00</lastmod>
		<changefreq>daily</changefreq>
		<priority>1</priority>
	</url>
</urlset>

Alternate

You can add alternate for multi-lingual page. Ex:

$url->set_alternate('fr-fr','http://google.fr');

Output:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
	<url>
		<loc>http://google.com</loc>
		<lastmod>2010-06-17T19:48:12+01:00</lastmod>
		<changefreq>daily</changefreq>
		<priority>1</priority>
		<link rel="alternate" hreflang="fr-fr" href="http://google.fr"/>
	</url>
</urlset>

Don't forget to add a set_alternate for the current page:

  $url->set_alternate('en','http://google.com');
