How to create a sitemap using PHP & MySQL
So I'm kinda stuck here. I have a website with a pretty big database, that constantly changes. Now I want to help the search engines by supplying a sitemap.xml file. Normally I would use a webservice that would do this, but thats not really possible in this case.
To be honest. I have no clue where to start. How would I go about doing this? Sorry if this is a too basic question, but Google couldn't help me.
Edit: Some more info. DB is currently 1k pages. Want to go up to like 10k. I use Mysql to echo this from my database, and then htaccess to rewrite the URLs. (PHP's get ID, etc)
