    Compare symfony 1.4 and Symfony 2

    Recently I have been at the crossroads of choosing between symfony 1.4 and Symfony2. This is a short list of pros and cons that helped with the decision making.

    Other factors to consider:

    Symfony 1


    • Knows it very well. Public API as well as internal workings.
    • PEAR for plugin management
    • Tried tested and true framework
    • Lots of plugins off the shelf from the community
    • I18N / L10N database for dates, etc complete ICU data
    • Well known best practices, naming conventions, configuration framework
    • Know what solution fits the job (when to use filters, helpers, extend internal components, etc)
    • Lots of documentation, how to’s, guides, tutorials, etc


    • Non xunit testing framework (lime)
    • Slower then symfony 2
    • End of maintenance 11/2012
    • Older technology
    • Does not take advantage of PHP 5.3 namespaces

    Symfony 2


    • ESI – edge side includes. Big performance boost if used correctly.
    • Dependancy Injection and decoupling of modules
    • Takes advantage of PHP 5.3 – namespaces, etc. This provides much cleaner code.
    • Uses standard logging, etc other components from Zend
    • Standardized testing framework (PHPUnit)
    • Twig templating seem to provide succinct syntax
    • Mongo DB support out of the box
    • Doctrine 2


    • New to the team. Learning curve
    • Not finished development. Target is March 2011 for final
      • API not stable yet
      • Not as many projects in production
      • No admin generator bundle
    • Some modules we need may not be built yet
    • Seems like only support for handling install / upgrade / dependancies of bundles in git sub modules. No PEAR2 support (yet?)
    • Lack of complete documentation and how to’s

    I actually had a small Q&A with symfony creator Fabien Potencier:

    Me: Are there plans to integrate Pyrus package management into Symfony 2 for bundles? Is GIT submodules all there is / planned?

    Fabien: We have something planned, but it’s too early to talk about it. I can say that the tools will be more flexible than Pyrus and will probably be something on top of it (to be able to install a bundle hosted on Git without the need to create a PEAR package for instance).

    Me: Are there plans to create a Jobeet style end-to-end application tutorial? At what date?

    Fabien: No. However, a book is being written.

    Me: Are there any feature sets of Symfony 2 that are lacking compared to the more mature symfony 1?

    Fabien: The admin generator. But that’s something we will work on soon.

    Me: Does Symfony 2 have a supported way to handle an asset CDN other then a hack like the override of “_compute_public_path()” helper in symfony 1?

    Fabien: Yes, it is supported out of the box.
