Since I'm new to Joomla I would like to know whether there is a way to change the administrator URL by using PHP rather than using a plugin or extensions. As far as I see using a 3rd party component is risky. I really don't want to use 3rd party extensions at all in mysite. How can I get it done?
By default Joomla administrator URL is yoursitename/administrator.
changing constants in /includes/defines.php and /administrator/includes/defines.php does not work.
Thanks
