Thank you, exactly what I was looking for. However, it looks like the doesn't update by itself daily. In order to have it updated, I need to save the sitemap-urls.txt file. There is a way hoe I can have this done automatically everyday?

You need a cron job + the source of the URLs (database/json or whatever) and a mofified php script like this...

Hi,

Thank you for your reply.

Do you have a working solution for this?

Hello,
thank you very much for your work! Is it possible to make script for case when URLs more than 50K? It requires index sitemap file.

@Vision20202 See https://gist.github.com/artlung/613e6ac577a170bf2b4b9045486f129e for a longer list of URLs. This breaks up the longer list up into chunks according to the rules for sizing.

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.

Thank you very much!
