Singular

Usage

$items = array(
    new SiteMapItem("http://example.com"),
    new SiteMapItem("http://example.com/foo", "2016-04-16", "monthly", 0.8),
    new SiteMapItem("http://example.com/bar", null, "always", 0.6)
);

$collection = new SiteMapCollection($items);

echo $collection->toXml();

Output

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
    <url>
        <loc>http://example.com</loc>
    </url>
    <url>
        <loc>http://example.com/foo</loc>
        <lastmod>2016-04-16</lastmod>
        <changefreq>0.8</changefreq>
        <priority>monthly</priority>
    </url>
    <url>
        <loc>http://example.com/bar</loc>
        <changefreq>0.6</changefreq>
        <priority>always</priority>
    </url>
</urlset>

Multiple

Usage

// configure output directory, URL prefix and URLs per site map
$siteMapWriter = new SiteMapXMLWriter('/var/www/example.com', "http://example.com", 50000);

// add records to writer
$siteMapWriter->addItem(new SiteMapItem("http://example.com"));
$siteMapWriter->addItem(new SiteMapItem("http://example.com/foo", "2016-04-16", "monthly", 0.8));
$siteMapWriter->addItem(new SiteMapItem("http://example.com/bar", null, "always", 0.6));
$siteMapWriter->addItem($item);

// finish generation and write index file
$siteMapWriter->writeSiteMapIndex();

Output

/var/www/example.com/sitemap.xml

<?xml version="1.0" encoding="UTF-8"?>

Using language annotations

Usage

// configure output directory, URL prefix and URLs per site map
$siteMapWriter = new SiteMapXMLWriter('/var/www/example.com', "http://example.com", 50000);

// add records to writer
$siteMapWriter->addItem(new SiteMapItem("http://example.com"));

// optional: add alternate links for specific language pages
$item = new SiteMapItem("http://example.com/foo-bar");
$item->addRelAlternate(array(
                               "hreflang" => "en",
                               "href" => "http://example.com/foo-bar"
                           )
                       );
$item->addRelAlternate(array(
                               "hreflang" => "de",
                               "href" => "http://example.com/de/foo-bar"
                           )
                       );
$siteMapWriter->addItem($item);

// finish generation and write index file
$siteMapWriter->writeSiteMapIndex();

Output
