Cartographer

A sitemap generation tool for PHP following the Sitemap Protocol v0.9, based on the work of Dan Horrigan (tackk/cartographer).

This fork was originally created to address vulnerabilities arising from outdated dependencies and along the way became compatible with PHP 8, bringing the original features into the current context.

Cartographer can handle Sitemaps of any size. When generating sitemaps with more than 50,000 entries, the sitemap becomes a "map of maps" (i.e. nested sitemaps).

Supported PHP/HHVM Versions

• PHP: >= 8.0.2

Installation

Composer CLI

composer require creativefactoryrv/cartographer:1.*

composer.json

{
    "require": {
        "creativefactoryrv/cartographer": "1.*"
    }
}

Basic Sitemap

If you have a sitemap that is under 50,000 items, you can just use the Sitemap class, and avoid the Sitemap Generator.

use CreativeFactoryRV\Cartographer\ChangeFrequency;
use CreativeFactoryRV\Cartographer\Sitemap;

$sitemap = new Sitemap();
$sitemap->add('http://foo.com', '2005-01-02', ChangeFrequency::WEEKLY, 1.0);
$sitemap->add('http://foo.com/about', '2005-01-01');

// Write it to a file
file_put_contents('sitemap.xml', (string) $sitemap);

// or simply echo it:
header ('Content-Type:text/xml');
echo $sitemap->toString();

Output

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>http://foo.com</loc>
    <lastmod>2005-01-02T00:00:00+00:00</lastmod>
    <changefreq>weekly</changefreq>
    <priority>1</priority>
  </url>
  <url>
    <loc>http://foo.com/about</loc>
    <lastmod>2005-01-01T00:00:00+00:00</lastmod>
  </url>
</urlset>

Basic Sitemap Index

If you want to build a Sitemap Index, separate from the Sitemap Generator, you can!

$sitemapIndex = new CreativeFactoryRV\Cartographer\SitemapIndex();

$sitemapIndex->add('http://foo.com/sitemaps/sitemap.1.xml', '2012-01-02');
$sitemapIndex->add('http://foo.com/sitemaps/sitemap.2.xml', '2012-01-02');

// Write it to a file
file_put_contents('sitemap.xml', (string) $sitemapIndex);

// or simply echo it:
header ('Content-Type:text/xml');
echo $sitemapIndex->toString();

Output

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>http://foo.com/sitemaps/sitemap.1.xml</loc>
    <lastmod>2012-01-02T00:00:00+00:00</lastmod>
  </url>
  <url>
    <loc>http://foo.com/sitemaps/sitemap.2.xml</loc>
    <lastmod>2012-01-02T00:00:00+00:00</lastmod>
  </url>
</sitemapindex>

Sitemap Factory

The Sitemap Factory create Sitemaps and Sitemap Indexes and writes them to the Filesystem. It can be used to generate full Sitemaps with more than 50,000 URLs.

If more than one sitemap is generated, it will create a Sitemap Index automatically.

Instantiating

The factory uses Flysystem to write the sitemaps. This means you can write the sitemaps to Local Disk, S3, Dropbox, wherever you want.

<?php

use CreativeFactoryRV\Cartographer\SitemapFactory;
use League\Flysystem\Filesystem;
use League\Flysystem\Local\LocalFilesystemAdapter;

$adapter = new LocalFilesystemAdapter(__DIR__ . '/sitemaps');
$filesystem = new Filesystem($adapter);

$sitemapFactory = new SitemapFactory($filesystem);

Base URL

The Base URL is used when generating the Sitemap Indexes, and for the returned entry point URL.

You can set the Base URL:

$sitemapFactory->setBaseUrl('http://foo.com/sitemaps/');

You can get the current base URL using getBaseUrl().

Creating a Sitemap

To create a sitemap you use the createSitemap method. This method requires an Iterator as its only parameter.

<?php

use CreativeFactoryRV\Cartographer\SitemapFactory;
use League\Flysystem\Filesystem;
use League\Flysystem\Local\LocalFilesystemAdapter;

$adapter = new LocalFilesystemAdapter(__DIR__ . '/sitemaps');
$filesystem = new Filesystem($adapter);

$sitemapFactory = new SitemapFactory($filesystem);
$sitemapFactory->setBaseUrl('http://foo.com/sitemaps/');

$entries = [
    [
        'url' => 'http://example.com/page1',
        'lastmod' => '2023-04-01',
        'changefreq' => 'daily',
        'priority' => '1.0'
    ],
    [
        'url' => 'http://example.com/page2',
        'lastmod' => '2023-04-02',
        'changefreq' => 'weekly',
        'priority' => '0.8'
    ],
];

$iterator = new ArrayIterator($entries);

// Returns the URL to the main Sitemap/Index file
$mainSitemap = $sitemapFactory->createSitemap($iterator);

Return Value

The two creation methods (createSitemap and createSitemapIndex) will return the URL of the root sitemap file. If there is only 1 sitemap created, it will return just that URL. If multiple sitemaps are created, then a Sitemap Index is generated and the URL to that is returned.

List of Created Files

You can get a list (array) of files the Factory has created by using the getFilesCreated method.

$files = $sitemapFactory->getFilesCreated();

Running Tests

This assumes you ran composer update.

From the repository root, run:
