How to correctly change url using rewrite rule in htaccess?

Question

PHP

I'm going to make readable URLs like this on the site -
site.ru/id/title.html
Here id and title are GET parameters that initially have this kind of
site.ru/blog.php?id=1500&title=interesting-article
All this I want to use .htaccess and rewrite rules to remake this
site.ru/1500/interesting-article.html Please help me
make a rule with a regular expression that allows this to be implemented.
