I'm currently using a CMS solution that does not generate any type of Sitemap for use with Google/Bing/Yahoo!/etc. I've requested it for 4 years now but they do not show any interest in adding it any time soon.
With that being said, I'm trying to find a way to create a sitemap for 1) all of our pages over 5,000; 2) all of our images; and 3) all of our documents.
Can anyone help me with this? I know my way around PHP and would like to code this up that way but I don't know where to start with crawling my site to generate the links needed. I tried https://github.com/jdevalk/XML-Sitemap-PHP-Script but had no luck as it only returned the 5 pages in the root and none of the child pages inside folders like it was suppose to. It also showed our last modification date as 1970 which is incorrect.
