My root folder structure is as follows:
I have an index.php as the home page and I want it to load when i simply go to my domain (ex: http://example.com)
Then, I have user.php page that GET data and show the user. current url http://example.com/user.php?u=johndoe
I want it to be http://example.com/johndoe
and I want it to identify other php files and folders without any conflict with above structure.
(http://example.com/about not interpret as http://example.com/user.php?u=about or http://example.com/folder as http://example.com/user.php?u=folder)
I appreciate a SEO friendly answer. Thank you
