Flyr is a simple and extensible PHP micro-framework. It aims to be fast and lightweight while including common utilities like routing, logging, templates, and session/cookie handling. Flyr can be installed via Composer and includes features like RESTful routing, PHP and Twig templates, and APIs for managing HTTP headers, sessions, and cookies. The framework focuses on being easy to use and extend while providing the essential tools for building applications.

1. Flyr – PHP micro framework

2. There are a lot of frameworks, each one with their particularities. There are really good
frameworks like laravel, codeigniter, cakephp, etc.
Flyr wants to be easy, simple and extensible. The goal is develop a fast micro-framework
which be so fast as user needs to develop applications.
Why try to remake validators, uploaders, orms and more software pieces if you can find
them in github with great quality and well tested?
Then you can add those libraries with a package manager like composer in your flyr
project.
Why another framework?

3. Flyr comes with a set of utilities:
- Router system with support for GET, POST, PUT and DELETE methods.
- Simple log component with email and file support.
- Http header manipulation.
- Cookies encryption.
- Simple cookie and session api.
- Easy multi-language component.
- Twig and php templates.
- Simple application skeleton for organize your project.
- Little mail sender support with PHPMailer.
What contains Flyr?

4. Installing flyr is as simple as creating a composer project or downloading the zip file inside
the flyr github REPOSITORY that contains all packages needed to run your application.
Run the following command to start a new project(at the current moment):
> composer create-project “flyr/flyr”:“1.0.*@dev”
Or simply download Flyr.zip in https://github.com/SiroDiaz/Flyr.
Now you have installed a copy of Flyr framework and you are ready to start developing.
How to install Flyr?

5. You can design a REST API easily using four request methods: GET, POST, PUT and DELETE.
Also, each route can contain parameters.
Finally you can pass a callback(anonym function) or the controller and method name. This
last option would be better for organize your project.
To resume this part you will see a few lines of code to understand better all refered to
routes.
Routes

6. Routes example

7. • Flyr also provides support for simple PHP templates (with tags <?php ?>) and Twig
template engine.
• You can render templates with the render method.
• But not only one template can be rendered for show in the browser, also you are able
to render multiple php or twig templates calling multiple times render method.
All templates are saved inside the folder app/views/ and all Twig templates are
automatically cached.
Views

8. Views example

9. For developing the REST of APIs you will need to return in your response body a data type
like JSON or XML and must be defined the response encoding as application/json or
text/xml for each data type.
You can set all response headers using the header->set method.
Maybe you need to remove headers like X-powered-by , redirect or send a response code.
It is simple and you can see the following examples using header object.
HTTP headers

10. HTTP headers example

11. Session and cookies have a new API for make many actions in the correct way like
deleting sessions and cookies, encrypting cookies or prevent cookie access from the
browser.
In the PHP cofiguration file (Flyr/Config/php_config.php) cookies and sessions are
correctly cofigured for avoid main source of session hijack.
Cookies methods are: create, delete, deleteAll, set, get.
Session methods are: start, set, get, delete, deleteAll.
You can see the following examples:
Managing sessions and cookies

13. Other important object is the flyr loader. You can load helpers and language files. Helpers
are files containing functions or classes to solve a specific group of problems. For example,
you can create a file called string_helper.php that has some functions to manipulate strings.
In the following example you can see how to load a language file containing the seven days
in Spanish:
Loader

14. Loading a language file example
A language file with an
associative array style
Loading the language file named ‘days.php’
inside the language folder ‘es’
