XML Sitemap Generator


There are two versions of the sitemap generator. One script to use with BASH (Linux/Unix) and one script written in PHP.

Sitemap format: http://www.sitemaps.org/protocol.html

XML Sitemap Generator - BASH
XML Sitemap Generator - PHP


XML Sitemap Generator - BASH


The BASH script is using WGET to download the website. The first script parameter is the website URL. The second parameter is the output file (sitemap file) and is optional. See line 116-123 to exclude links.

Example 1 (output in current directory): sh sitemap.sh https://www.example.com

Example 2: sh sitemap.sh https://www.example.com /var/www/mysite/sitemap.xml


sitemap.xml


Add the XML file to your /robots.txt.

Example line for the robots.txt:

Sitemap: https://www.example.com/sitemap.xml

XML Sitemap Generator - PHP


This is a simple and small PHP script that I wrote quickly for myself to create a XML sitemap of my page for Google and other search engines. Maybe others can use the script too.

Plans for 2.5: Sitemap index file for websites with more than 50000 pages or XML files larger than 10 MB. Maybe gzip compression for the sitemap file.

If the PHP script is very slow, then there are problems with the DNS resolution. I have no fix at the moment. Try the BASH Version of the sitemap generator.


The script


The configuration settings are between line 62 and 102. At first, set the SITE variable at line 68 with the URL of your website.
Example: define ("SITE", "https://www.example.com");

The script can be started as CLI script or as website. CLI is the preferred way to start this script.

CLI scripts are started from the command line, can be used with CRON and so on. You start it with the php program.

CLI command to create the XML file: php sitemap-2.4.php

To start the program with your webserver as website change in the script the line 74 from
   define ("CLI", true);
to
   define ("CLI", false);


sitemap.xml


Add the XML file to your /robots.txt.

Example line for the robots.txt:

Sitemap: https://www.example.com/sitemap.xml

Note for version 1.0


When only the first page is scanned, then add a slash at the end of the start url at line 34.

Example: $url = "http://www.example.com/";

Thanks to David Cordovez for that info. This problem is fixed in 2.x.
