How to get all header information in laravel?

@dana 

In Laravel, you can retrieve all header information by using the header() method on the IlluminateHttpRequest object.

Here is an example of how you can get all header information in Laravel:

1
2
3
4
5
6
7
8

use IlluminateHttpRequest;

public function getHeaders(Request $request)
{
    $headers = $request->header();

    return $headers;
}

In this example, the header() method returns an associative array of all the headers. You can then use this array to access specific headers or loop through all the headers.

Alternatively, you can also use the headers property on the IlluminateHttpRequest object to access specific headers. For example:

1
2
3
4
5
6
7
8

use IlluminateHttpRequest;

public function getHeader(Request $request)
{
    $contentType = $request->headers->get('Content-Type');

    return $contentType;
}

In this example, the get() method of the headers property is used to retrieve the value of the Content-Type header specifically.
