How to Get Headers Data from Request in Laravel ?

In this article we will learn to get headers data from request in laravel. Http Request headers are used to send the information to server like what type of content clients accept, Content type or authorizations technique used to validate the request.To retrieve the headers data in laravel we need to call header method of request class.

Sometimes we send some hidden information like token or cookies in the headers which we want to access at server side so to access that in laravel we use header method of request as follow

$request->header(); // get all headers

or

$data = request()->header('header_name'); // array list of headers
$data['field_name'];

});
