Symfony

It provides an architecture, components and tools for developers to build complex web applications faster. Choosing symfony allows you to release your applications earlier, host and scale them without problem, and maintain them over time with no surprise. 

Symfony is based on experience. It does not reinvent the wheel: it uses most of the best practices of web development and integrates some great third-party libraries.

Symfony has low performance overheads when dealing with an environment that supports a PHP accelerator.

Symfony is aimed at building robust applications in an enterprise context, and aims to give developers full control over the configuration: from the directory structure to the foreign libraries, almost everything can be customized. To match enterprise development guidelines, Symfony is bundled with additional tools to help developers test, debug and document projects.

I.      PHP Framework

In order to better understand what a framework is, let’s leave the world of computer science for a moment and imagine a mountaineering adventure. Developing an application is very similar to climbing a rock wall: you are at the bottom (you have an application to be created) and you need to reach the summit (and be pleased with the achievement of designing an application that works perfectly.)

If no one has ever climbed the wall in question, you will have to get by on your own: testing routes, occasionally backtracking so that you don’t get stuck in a corner, driving in pitons, etc. In contrast, if the wall has already been conquered, those who have gone before you will already have done this trial and error work, opening up possible paths (the frame) and installing the tools that will facilitate the climb (your work).

Basically, a framework consists of:

·         A toolbox - a set of prefabricated, rapidly integratable software components. This means that you will have to write less code, with less risk of error. This also means greater productivity and the ability to devote more time to doing those things which provide greater added value, such as managing guiding principles, side effects, etc.

·         A methodology – an “assembly diagram” for applications. A structured approach may seem constraining at first. But in reality it allows developers to work both efficiently and effectively on the most complex aspects of a task, and the use of Best Practices guarantees the stability, maintainability and upgradeability of the applications you develop.

And although it might be obvious, we thought it best to say it anyway – Symfony is a PHP framework, which means that it permits web applications to be built in PHP!

II.   Development roadmap

The upcoming new release version of Symfony will include new features such as: 

§  A new form generation framework, first introduced in version 1.2

§  A new admin generator (referred to as scaffolding in Rails) which makes use of the new form framework and is no longer implemented as a helper.

§  Object relationship mapping declared in a separate plug-in, rather than being integrated into the ORM

§  Choice of ORM (Doctrine or Propel, or a combination of the two)

§  Classes re-factored for looser coupling between objects, allowing for more user flexibility in using objects and fewer dependencies (similar in principle to the Zend Framework).

§  Routing rules and route objects more closely follow REST design principles.

III. conclusion

      We have described about Symfony. Symfony is a web application framework written in PHP. Symfony is aimed at building robust applications in an enterprise context, and aims to give developers full control over the configuration: from the directory structure to the foreign libraries, almost everything can be customized. To match enterprise development guidelines, Symfony is bundled with additional tools to help developers test, debug and document projects.
