I have a code igniter controller ," TEST " . and I want to access this controller in REST API.
When I include this controler file using " include_once(APPPATH.'/controllers/test.php'); " , everything works fine.
But Is this the only way to access the controller inside REST API? or is there any other way to do so?
I'm not fully sure what you're trying to do, but it looks like a rather unlogical approach.
Have a look at creating own libraries. The REST API should be easy to implement through there and it's much more logical.
