I am sorry if that question is a little silly. I am not so familiar with the .htaccess.
Assume that I have a file folder/index.php, it is dynamic. So, to access this, users need to enter something like folder/index.php?id=11111.
Now I want that the users can go to folder/index.php?id=11111 by entering only folder.php/11111.
How could it be done? Thank you very much if you can give a full solution.
