Installation

Installation via Composer is very simple:

composer require EnvyTek/
composer require EnvyTek/sitemap:dev-master

After that, make sure your application autoloads Composer classes by including vendor/autoload.php.

How to use it

use EnvyTek\Sitemap\Sitemap;
use EnvyTek\Sitemap\Index;

// create sitemap
$sitemap = new Sitemap(__DIR__ . '/sitemap.xml');

// add some URLs
$sitemap->addUrl(new Url('http://example.com/mylink1'));
$sitemap->addUrl(
    (new Url('http://example.com/mylink2'))
        ->setLastModified(new \DateTime())
);
$sitemap->addUrl(
    (new Url('http://example.com/mylink3'))
        ->setLastModified(new \DateTime())
        ->setChangeFrequency(Frequency::HOURLY)
);
$sitemap->addUrl(
    (new Url('http://example.com/mylink4'))
        ->setChangeFrequency(Frequency::DAILY)
        ->setLastModified(new \DateTime())
        ->setPriority(0.3)
);

// write it
$sitemap->write();

// get URLs of sitemaps written
$sitemapFileUrls = $sitemap->getSitemapUrls('http://example.com/');

// create sitemap for static files
$staticSitemap = new Sitemap(__DIR__ . '/sitemap_static.xml');

// add some URLs
$staticSitemap->addUrl(new Url('http://example.com/about'));
$staticSitemap->addUrl(new Url('http://example.com/tos'));
$staticSitemap->addUrl(new Url('http://example.com/jobs'));

// write it
$staticSitemap->write();

// get URLs of sitemaps written
$staticSitemapUrls = $staticSitemap->getSitemapUrls('http://example.com/');

// create sitemap index file
$index = new Index(__DIR__ . '/sitemap_index.xml');

// add URLs
foreach ($sitemapFileUrls as $sitemapUrl) {
    $index->addSitemap($sitemapUrl);
}

// add more URLs
foreach ($staticSitemapUrls as $sitemapUrl) {
    $index->addSitemap($sitemapUrl);
}

// write it
$index->write();

Multi-language sitemap

use EnvyTek\Sitemap\Sitemap;

// create sitemap declaring you need alternate links support
$sitemap = new Sitemap(__DIR__ . '/sitemap_multi_language.xml', [AlternateLink::class]);

// add some URLs

$sitemap->addUrl(
    (new Url('http://example.com/en/mylink2'))
        ->setLastModified(new \DateTime())
        ->setChangeFrequency(Frequency::HOURLY)
        ->add(new AlternateLink('en', 'http://example.com/en/mylink1'))
        ->add(new AlternateLink('ru', 'http://example.com/ru/mylink1'))
);

$sitemap->addUrl(
    (new Url('http://example.com/en/mylink2'))
        ->setLastModified(new \DateTime())
        ->setChangeFrequency(Frequency::HOURLY)
        ->add(new AlternateLink('en', 'http://example.com/en/mylink2'))
        ->add(new AlternateLink('ru', 'http://example.com/ru/mylink2'))
);

// write it
$sitemap->write();

Options

There are methods to configure Sitemap instance:

• setMaxUrls($number). Sets maximum number of URLs to write in a single file. Default is 50000 which is the limit according to specification and most of existing implementations.
• setMaxBytes($number). Sets maximum size of a single site map file. Default is 10MiB which should be compatible with most current search engines.
• setBufferSize($number). Sets number of URLs to be kept in memory before writing it to file. Default is 10. Bigger values give marginal benefits. On the other hand when the file size limit is hit, the complete buffer must be written to the next file.
• setUseIndent($bool). Sets if XML should be indented. Default is true.
• setUseGzip($bool). Sets whether the resulting sitemap files will be gzipped or not. Default is false. zlib extension must be enabled to use this feature.

There is a method to configure Index instance:

• setUseGzip($bool). Sets whether the resulting index file will be gzipped or not. Default is false. zlib extension must be enabled to use this feature.

Running tests

In order to run tests perform the following commands:

composer install
./vendor/bin/phpunit
