Library for generating Google sitemap XML files
License: MIT License
Languages: PHP
For the 90's people, i'm keeping this repository as 5.2 compatible. If you need PSR-0 and Composer compatible version, here is a fork that maintained by Evert Pot.
Fast and lightweight class for generating Google sitemap XML files and index of sitemap files. Written on PHP and uses XMLWriter extension (wrapper for libxml xmlWriter API) for creating XML files. XMLWriter extension is enabled by default in PHP 5 >= 5.1.2. If you having more than 50000 url, it splits items to seperated files. (In benchmarks, 1.000.000 url was generating in 8 seconds)
Include Sitemap.php file to your PHP document and call Sitemap class with your base domain.
include 'Sitemap.php';
$sitemap = new Sitemap('http://example.com');
Now, we need to define path for saving XML files. This can be relative like xmls
or absolute /path/to/your/folder
and must be a writable folder. In default it uses same folder with your script.
$sitemap->setPath('xmls/');
Generated XML file names defaulted to sitemap-*.xml
, you can customize prefix of filenames with setFilename
method.
$sitemap->setFilename('customsitemap');
We'll add sitemap url's with addItem
method. In this method, only first parameter (location) is required.
$sitemap->addItem('/', '1.0', 'daily', 'Today');
$sitemap->addItem('/about', '0.8', 'monthly', 'Jun 25');
$sitemap->addItem('/contact', '0.6', 'yearly', '14-12-2009');
$sitemap->addItem('/otherpage');
w/ method chaining.
$sitemap->addItem('/projects', '0.8')->addItem('/somepage')->addItem('/hiddenpage', '0.4', 'yearly', '01-01-2011')->addItem('/rss');
from a sql result, or whatever.
$query = Doctrine_Query::create()
->select('p.created_at, p.slug')
->from('Posts p')
->orderBy('p.id DESC')
->useResultCache(true);
$posts = $query->fetchArray(array(), Doctrine_Core::HYDRATE_ARRAY);
foreach ($posts as $post) {
$sitemap->addItem('/post/' . $post['slug'], '0.6', 'weekly', $post['created_at']);
}
If you need to change domain for sitemap instance, you can override it via setDomain
method.
$sitemap->setDomain('http://blog.example.com');
Finally we create index for sitemap files. This method also closes tags of latest generated xml file.
$sitemap->createSitemapIndex('http://example.com/sitemap/', 'Today');
When you run your script, it generates and saves XML files to given path.
sitemap-0.xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>http://example.com/</loc>
<priority>1.0</priority>
<changefreq>daily</changefreq>
<lastmod>2011-04-07</lastmod>
</url>

</urlset>
sitemap-index.xml
<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<sitemap>
<loc>http://example.com/sitemap/sitemap-0.xml</loc>
<lastmod>2011-04-07</lastmod>
</sitemap>
</sitemapindex>
You need to submit sitemap-index.xml to Google Sitemaps.
Please note that, generating sitemaps not overrides any previous generated sitemap file. You need to delete old files before the operation.
$ rm -rv sitemap-*
For the truncating a file with php, use the following snippet:
$handle = fopen("/path/to/sitemap/file.xml", "w");
fclose($handle);
