php-guzzleHow to add an authorization header in PHP Guzzle?

Adding an authorization header in PHP Guzzle is a simple process.

$client = new GuzzleHttp\Client();
$res = $client->request('GET', 'http://httpbin.org/get', [
    'headers' => [
        'Authorization' => 'Bearer YOUR_TOKEN_HERE'
    ]
]);

The output of the above code will be a response object containing the response from the server.

The code consists of the following parts:

1. $client = new GuzzleHttp\Client(); - This creates a new Guzzle client object.
2. $res = $client->request('GET', 'http://httpbin.org/get', [ - This sends a GET request to the specified URL.
3. 'headers' => [ - This is an array of headers to be sent with the request.
4. 'Authorization' => 'Bearer YOUR_TOKEN_HERE' - This sets the Authorization header with the specified token.
5. ]); - This closes the array of headers and the request method.
