• 🔒 Type-safe enums - Use the Frequency enum for change frequency values
• 🎯 Standards compliant - Follows sitemaps.org protocol specifications
• 📝 Automatic handling - Manages large sitemaps (splits after 40,000 URLs)
• 🔄 Sitemap index support - Create sitemap indexes for multiple sitemaps

Installation

Install via Composer:

composer require jdz/sitemap

Quick Start

Basic Sitemap

<?php

require_once 'vendor/autoload.php';

use JDZ\Sitemap\Map;
use JDZ\Sitemap\Url;
use JDZ\Sitemap\Frequency;

// Create a sitemap
$sitemap = new Map('/path/to/public', 'sitemap', 'https://example.com');

// Add URLs
$sitemap->addItem(new Url('/', 'now', Frequency::DAILY, 0.9));
$sitemap->addItem(new Url('/about', 'now', Frequency::WEEKLY, 0.8));
$sitemap->addItem(new Url('/contact', 'now', Frequency::MONTHLY, 0.7));

// Write sitemap to file
$sitemap->write();

This generates: /path/to/public/sitemap/sitemap.xml

Sitemap Index

<?php

require_once 'vendor/autoload.php';

use JDZ\Sitemap\Index;
use JDZ\Sitemap\Map;
use JDZ\Sitemap\Group;
use JDZ\Sitemap\Url;
use JDZ\Sitemap\Frequency;

$publicPath = '/path/to/public';

// Create sitemap index
$index = new Index($publicPath);

// Create main sitemap
$sitemap = new Map($publicPath, 'sitemap', 'https://example.com');
$sitemap->addItem(new Url('/', 'now', Frequency::DAILY, 0.9));
$sitemap->addItem(new Url('/blog', 'now', Frequency::DAILY, 0.8));
$sitemap->write();

// Add to index
foreach ($sitemap->writtenFilePaths as $path) {
    $index->addItem(new Group('https://example.com/sitemap/' . $path));
}

// Create subdomain sitemap
$subSitemap = new Map($publicPath, 'subdomain', 'https://blog.example.com');
$subSitemap->addItem(new Url('/', 'now', Frequency::DAILY, 0.9));
$subSitemap->addItem(new Url('/posts', 'now', Frequency::WEEKLY, 0.8));
$subSitemap->write();

// Add to index
foreach ($subSitemap->writtenFilePaths as $path) {
    $index->addItem(new Group('https://example.com/sitemap/' . $path));
}

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

This generates:

• /path/to/public/sitemap.xml (index)
• /path/to/public/sitemap/sitemap.xml
• /path/to/public/sitemap/subdomain.xml

Frequency Enum Cases

The Frequency enum provides type-safe change frequency values:

use JDZ\Sitemap\Frequency;

Frequency::ALWAYS   // 'always'
Frequency::HOURLY   // 'hourly'
Frequency::DAILY    // 'daily'
Frequency::WEEKLY   // 'weekly'
Frequency::MONTHLY  // 'monthly'
Frequency::YEARLY   // 'yearly'
Frequency::NEVER    // 'never'

Examples

Creating a URL with all parameters

use JDZ\Sitemap\Url;
use JDZ\Sitemap\Frequency;

$url = new Url(
    '/products/item-123',           // Location (path)
    '2023-12-07 10:30:00',         // Last modification date
    Frequency::WEEKLY,              // Change frequency
    0.8                             // Priority (0.0 to 1.0)
);

Using default values

// Only path is required, other parameters have defaults:
// - lastmod: 'now' (current timestamp)
// - changefreq: Frequency::WEEKLY
// - priority: 0.5

$url = new Url('/simple-page');

Handling duplicate URLs

Duplicate URLs are automatically ignored:

$sitemap->addItem(new Url('/page1'));
$sitemap->addItem(new Url('/page1')); // Ignored
$sitemap->addItem(new Url('/page2'));
// Only 2 URLs will be in the sitemap

Automatic file splitting

The library automatically creates multiple sitemap files when you exceed 40,000 URLs:

$sitemap = new Map($publicPath, 'sitemap', 'https://example.com');

for ($i = 1; $i <= 100000; $i++) {
    $sitemap->addItem(new Url("/page-{$i}"));
}

$sitemap->write();

// Generates:
// - sitemap/sitemap.xml (URLs 1-40,000)
// - sitemap/sitemap-2.xml (URLs 40,001-80,000)
// - sitemap/sitemap-3.xml (URLs 80,001-100,000)

// Access generated files
print_r($sitemap->writtenFilePaths);
// Array: ['sitemap.xml', 'sitemap-2.xml', 'sitemap-3.xml']
