3. What is a software
framework?
• It is software that assists in structuring
an application, with the most common
bells and whistles to get you on running
almost instantly.

4. Why use a framework?
• It assist in not coding yourself in a corner.
• It allow you to focus on the software you have write
• It has all the basics built in already, no need to re-invent the
wheel
• It comes with ready made components like, authentication,
routing, configuration etc..

6. Choosing a framework
• Choosing a framework can be difficult
• Its personal choice
• Its up to you, with what you comfortable with
• There is no right and wrong when choosing
• Contribution and Support in open source is what makes
the software a preferred choice.

7. Symfony
• http://symfony.com/
• We use it at Afrihost.com
• It is the core of the business
• We run Symfony 1 and 2 concurrently

8. Getting Started
• Composer
• https://getcomposer.org/
• Composer is used to install different components to your
application.
• You decide what component you would like to use and
you install it - https://packagist.org/
• composer create-project symfony/framework-standard-edition
my_project_name

11. Now what?
• We need to view our application in the browser.
• php bin/console server:run
• This starts a server on the command line
• You would only do this when developing

12. Home

13. The Page – IT WORKS!

14. The Console
• ./bin/console

15. Bundles
• Symfony uses the term Bundle, for each unit of
packaged code that serves a particular purpose.
• For example, BlogBundle – it’s a bundle that should
contain code related to a Blog
• SecurityBundle – should have things related to security
stuff

16. Bundles
• Creating a bundle
• ./bin/console generate:bundle

17. Bundles

18. MVC
• Model
• View
• Controller

19. On To The Code!

20. Routing
• Routing can be configured by annotations, yml,
xml and PHP
• The most common configuration is using
annotation as the route is above the controller you
are currently working with.

21. Controllers
• The code in a controller must be lean
• All business logic must be separated from the
controller
• Create manager functions to consolidate business
logic to a particular bundle domain.

22. Displaying the page

23. Model
This is the data source
./bin/console doctrine:generate:entity

24. Model
• app/config/parameters.yml
• Setup the database information in the
parameters file
• This file is used for storing all the information
required for configuration
• Mail hosts, database connections. Etc..

25. Creating the table
• ./bin/console doctrine:schema:create

26. Putting it all together
• Now we have a model
• We can create a view to read the model and a
controller to add data to the model

27. Create a new Controller
ExampleBundleControllerDefaultController::userAction

28. Create a new View
src/ExampleBundle/Resources/views/Default/user.html.twig

29. Check out the result!
