how to remove index.php from my url in codeigniter

It's pretty much one of two things: Incorrectly-written .htaccess file, or the URI protocol isn't compatible with your server set up.

I'd recommend using the .htaccess example from the wiki link pistolPete posted. It works great for myself, and is a more thorough / better written than what you're currently using.
