How to remove public/index.php/ from url

If xxx/controller doesn't work, but xxx/index.php/controller does, then your htaccess is not working. Could be rewrite_module not loaded, or wrong permissions.
If xxx/controller doesn't work, but xxx/public/controller does, then your document root is set incorrectly inside apache.

If you have to resort to xxx/public/anything, then your document root is set incorrectly!
