SiteMapper

SiteMapper is a lightweight, chainable PHP library to generate SEO-friendly XML sitemaps dynamically.
Designed for modern PHP projects and frameworks (Laravel, Codeigniter, Symfony, plain PHP).

---

Features

• Fluent API: addUrl(...)->save() for concise, readable code.
• Add per-URL metadata: priority, lastmod and changefreq.
• generateXml() returns an XML string ready to return from controllers.
• outputXml() sends correct headers and echoes XML directly.
• saveToFile() writes sitemap XML to disk.
• Minimal dependencies — requires only PHP and SimpleXML.

---

Requirements

• PHP 7.4 or newer
• ext-simplexml enabled

---

Installation

Install via Composer:

composer require kri55h/php-sitemapper

Then autoload:

require 'vendor/autoload.php';

use Kri55h\SiteMapper;

Quick Example (recommended)

<?php
require 'vendor/autoload.php';

use Kri55h\SiteMapper;

$map = new SiteMapper();

// Add and save entries (pass full URLs)
$map->addUrl('https://example.com/about', 0.8, '2025-08-09', 'daily')->save()
    ->addUrl('https://example.com/contact', 0.5, '2025-08-09', 'weekly')->save();

// Return XML from a controller or script
header('Content-Type: application/xml; charset=UTF-8');
echo $map->generateXml();

Important: addUrl() stages a URL in memory. Call save() to commit the staged entry into the sitemap list — otherwise it will not appear in generateXml().

Full Example (all functions / backwards-compatible style)

<?php
require 'vendor/autoload.php';

use Kri55h\SiteMapper;

$map = new SiteMapper();

// Staged style: call setters, then save()
$map->addUrl('https://example.com/')
    ->setPriority(1.0)
    ->setLastModified('2025-08-09')
    ->setChangeFrequency('daily')
    ->save();

// Another entry, using positional args
$map->addUrl('https://example.com/about', 0.8, '2025-08-09', 'weekly')->save();

// Save sitemap to disk
$map->saveToFile(__DIR__ . '/public/sitemap.xml');

// Or output directly (sets header + echoes XML)
$map->outputXml();

Public API Reference

• addUrl(string $location, ?float $priority = null, ?string $last_modified = null, ?string $change_frequency = null): self Adds a staged URL entry. Pass a full URL (https://example.com/page). Returns $this for chaining.

• setPriority(float $priority): self Set priority (0.0 — 1.0) for the currently staged entry. Chainable.

• setLastModified(string $last_modified): self Set the last modified date (YYYY-MM-DD) for the currently staged entry. Chainable.

• setChangeFrequency(string $change_frequency): self Set change frequency (always|hourly|daily|weekly|monthly|yearly|never). Chainable.

• save(): self Commit the currently staged entry into the sitemap list. Throws RuntimeException if no loc was staged. Chainable.

• generateXml(): string Generate and return the sitemap XML string. Use this to return XML from controller routes.

• outputXml(): void Send Content-Type: application/xml; charset=UTF-8 and echo the generated XML. Convenience helper for quick endpoints.

• saveToFile(string $filePath): void Write the generated sitemap XML to the given file path.

Migration notes (from previous versions that had addBaseUrl())

If you upgraded from a version that supported addBaseUrl() and relative paths:

• Before (old):

$map->addBaseUrl('https://example.com');
$map->addUrl('/about');
echo $map->generateXml();

• Now (new):

$map->addUrl('https://example.com/about')->save();
echo $map->generateXml();

Why: The library no longer maintains global base URL state. This makes the API explicit and safer for mixed-domain usages.

Best practices

• Always call save() after addUrl() (or use positional arguments with addUrl(...)->save()).

• Use generateXml() to return XML from controllers (so the framework can manage responses).

• Use outputXml() only for simple scripts or endpoints where you want the library to send headers.

• For bulk imports, add entries in a loop and call save() per entry, or implement your own batching helper.
