How to return response text/html from controller in laravel 5?

Few days ago, i was working on my new project and project was migrate project php into laravel. I need to migrate apis, So in old php application it returns response as text and i have to keep same response in laravel 5.4 application. So i thought how we can do it, finally i got it, we can do it using response().

response() helper will help to return simple text. So in my php it was like as bellow:

PHP response:

<?php
	
	....
	....
	echo "return response";
	exit();
?>

Now i am going to give example of return response as text/html not json. In this example i am going to use response() for return simple text.

Laravel response in controller method:

/**
 * Show the application dashboard.
 *
 * @return \Illuminate\Http\Response
 */
public function logActivity(Request $request)
{
    $input = $request->all();
    return response('return response');
}

I hope you found, your solution from here....
