How to use

Request

This class exists to handle HTTP requests. Each one has a property on \Attw\Http\Request that returns an instance of \Attw\Http\Request\Method\RequestsCollection, that extends \Attw\Tool\Collection\ArrayCollection., _(*3)

The values of each property can be defined on constructor of the request class. If null (array()), the value will be the properties of the globals ($_GET, $_POST, $_FILES, $_SERVER, $_COOKIE)., _(*4)

Parameters order: Request([array $query = array(), [array $post = array(), [array $files = array(), [array $server = array(), [array $cookies = array()]]]]]), _(*5)

Example

With globals:, _(*6)

use Attw\Http\Request;

$_GET['foo'] = 'bar';
$request = new Request();
echo $request->query->get('foo');// bar

Without globals:, _(*7)

use Attw\Http\Request;

$request = new Request(['bar' => 'foo']);
echo $request->query->get('bar');// foo

Response

With it you can send a response to client machine. The response will send to the client if the request was executed with success (Status code is 200) or not (Status code is not 200), the content type to the brownser show (HTML, JSON, image, etc.) and others headers., _(*8)

You can create a collection of headers to send all in the same time or send one each one., _(*9)

On the instance of \Attw\Http\Response you can define the current status code and the version used of HTTP protocol: Response([$statusCode = 200, [$protocol = 'HTTP/1.1']])., _(*10)

Example:

Sending one header:, _(*11)

use Attw\Http\Response;

$response = new Response();
$response->sendHeader('Location', 'http://foo.bar'); //will redirect to http://foo.bar

Sending several headers:, _(*12)

$response->addHeader('Content-type', 'text/html');
$response->addHeader('Charset=UTF-8');
$response->sendAllHeaders();

Cookies

Cookies are, basically, some data that the server "ask" client to save. Every time that you access that domain, your machine sends to it all cookies saved to it. A cookie is exclusive of you, of your machine., _(*13)

The class used to set cookies is \Attw\Http\Cookie\Cookies and used to read a cookie is \Attw\Http\Request., _(*14)

Example

use Attw\Http\Cookie\Cookie;
use Attw\Http\Cookie\Cookies;
use Attw\Http\Request;

$cookies = new Cookies();
$cookie = new Cookie('foo', 'bar');//name: foo; value: bat
$cookies->set($cookie);
$request = new Request();
echo $request->cookie->get('foo');// bar
