Rewrite rules

Hello all,

I need to rewrite “myblog.com/post_exemple?my_var=1” in “myblog.com/post_title/my_var/1” and also use the content of the my_var in the “post_exemple” post.

For using my_var in the post I will use the plugin from here https://www.hongkiat.com/blog/execute-php-in-wordpress-post-page-and-widget-sidebar/ . I’m not sure if is the best solution.

But for the rerwite procedure I don’t know how to do.

Any idea?
