PHP already has a few things built in to make working with HTTP easier. For example there are the [superglobals](http://php.net/manual/en/language.variables.superglobals.php) that contain the request information.
These are good if you just want to get a small script up and running without much thought on maintenance. But if you want to write clean, maintanable, [SOLID](http://en.wikipedia.org/wiki/SOLID_%28object-oriented_design%29) code, then you will want a class with a nice object oriented interface that you can use in your application.

Once again, you don't have to reinvent the wheel and just install a package. I decided to write my own [HTTP component](https://github.com/PatrickLouys/http) because I did not like the existing components, but you don't have to do the same.

This will send the response data to the browser. If you don't do this, nothing happens as the `Response` object only stores data. This is handled differently by most other HTTP components where the classes send data back to the browser as a side-effect, so keep that in mind if you use another component.
Right now it is just sending an empty response back to the browser with the status code `200`, so to change that add the following code between the code snippets from above:

Remember that the object is only storing data, so you if you set multiple status codes before you send the response, the last one will be applied.

I will show you in later parts how to use the different features of the components. In the meantime, feel free to read the [documentation](https://github.com/PatrickLouys/http) or the source code if you want to find out how something works.
