Since v1.0.0

Description

NotExtendedStatus is a HttpStatus value object. It represents the HTTP 510 Not Extended status.

Public Interface

NotExtendedStatus has the following public interface:

// NotExtendedStatus lives in this namespace
namespace GanbaroDigital\HttpStatus\StatusValues\RuntimeError;

// our base classes and interfaces
use GanbaroDigital\HttpStatus\Interfaces\HttpRuntimeErrorStatus;
use GanbaroDigital\HttpStatus\Interfaces\HttpStatus;
use GanbaroDigital\HttpStatus\StatusValues\HttpStatusObject;

     */
    public function __construct();

    /**

     *

     */
    public function getStatusCode();

    /**

     *
     * @return string

How To Use

Construction

The constructor for NotExtendedStatus takes no parameters.

use GanbaroDigital\HttpStatus\StatusValues\RuntimeError\NotExtendedStatus;

$httpStatus = new NotExtendedStatus;

getStatusCode()

NotExtendedStatus::getStatusCode() returns the HTTP status code as an integer:

use GanbaroDigital\HttpStatus\StatusValues\RuntimeError\NotExtendedStatus;

$httpStatus = new NotExtendedStatus;
$statusCode = $httpStatus->getStatusCode();

// $statusCode contains the value '510' as an integer

HTTP status codes are part of the HTTP standards. Servers, proxies and clients use these codes to understand what happened with a HTTP request.

getReasonPhrase()

NotExtendedStatus::getReasonPhrase() returns the HTTP reason phrase as a string:

use GanbaroDigital\HttpStatus\StatusValues\RuntimeError\NotExtendedStatus;

$httpStatus = new NotExtendedStatus;
$reasonPhrase = $httpStatus->getReasonPhrase();

// $reasonPhrase contains the value 'Not Extended' as a string

HTTP reason phrases are part of the HTTP standards. They're RuntimeError, and are there for humans to read. Servers, proxies and clients may store, forward and log these reason phrases, but they should never actually parse them or use them to understand what happened with a HTTP request.

getStatusLine()

NotExtendedStatus::getStatusLine() returns the HTTP status line. This is the string that is printed after the HTTP protocol version at the start of any HTTP response.

use GanbaroDigital\HttpStatus\StatusValues\RuntimeError\NotExtendedStatus;

$httpStatus = new NotExtendedStatus;
$statusLine = $httpStatus->getStatusLine();

// $statusLine contains the value "510 Not Extended" as a string

// use $statusLine to set the response from your PHP app
header($_SERVER["SERVER_PROTOCOL"] ." " . $statusLine);
