/**
*
* This is a quick way to turn a simple text file
* with a very long list of urls in a text file (sitemap-urls.txt)
* Where "very long" is an expected url number greater than 10,000
* If loaded without a valid query parameter "page" it will load a
* Site Index site map, otherwise load the individual XML site map
* 10,000 urls into a valid XML Sitemap:
* http://en.wikipedia.org/wiki/Sitemaps
* Put this file sitemap.xml.php and sitemap-urls.txt at
* the webroot http://example.com/sitemap.xml.php
* Then add the text in quotes below to your robots.txt file as a new line:
* "Sitemap: http://example.com/sitemap.xml.php"
*
* Questions? email joe@artlung.com
*
* Based on https://gist.github.com/artlung/210438

Reported by @Vision20202:

I tried this version but received the following error:
Undefined index: page in .../sitemap/sitemap.xml.php on line 25

line 25: $page = (int)$_GET['page'];
Please help to solve the problem.

Code updated to address this issue.

@Vision20202 I updated to use the null coalescing operator available in PHP7. If you are using something older that won't work. What version of PHP are you using?
