symfony vs cakephp [closed]

Question

Just to balance out this thread, this is why I like symfony:

• uses PHP5
• it runs some really big sites like Yahoo! Answers, delicious, and Daily Motion.
• good documentation. the jobeet tutorial on the website is awesome. walks you straight through all of the features, and after you are done you feel like you can build anything.
• is highly modular; many of the symfony components work on their own.
• allows you to choose either Propel or Doctrine as your ORM. Doctrine is really great and easy to use.
• you can define your models with YAML or in PHP, its up to you. Some people don't like configuration files, and you can really limit their use if you want to steer clear of YAML.
• the updated symfony cli (as of 1.2) is awesome. I agree with abales, before this version it was a little wonky, but now it is very well documented and follows a predictable format.
• there are a lot, and i mean a lot, of similarities with ruby on rails, except that of course PHP isn't quite as pretty or flexible as Ruby(!). But, if you talk to a cake developer, they will probably say the opposite :)
• the symfony admin generator, which is a step up from CRUD (which also exists in symfony), is a huge time saver. Using your data model it will generate customizable admin interfaces complete with list views (index), create, and edit pages. It's not like basic crud where it generates the source and you go in and modify it... You actually can define how each field looks, which fields you want to include, what additional actions you can perform on each object, and so on.

Conceptually, I'd say the difference is this:

• CakePHP has a smaller learning curve. If you have never used a MVC framework, Cake will be easier to pick up and run with in a short amount of time.
• Symfony feels bit "bigger," not to say that it is slow, but that there is a lot of code back there that will let you do a lot of really advanced things when you need to.

The best advice I can give is to quickly try to set up a your own simple data model in both, and experiment with some basic interfaces, and just see which fits your own coding style the best. I think both frameworks have very active and passionate user communities and you won't regret your decision either way.

• CakePHP philosophy is similar to Ruby on Rails.
• CakePHP is better for medium projects.
• CakePHP is faster to learn.
• CakePHP is lighter than symfony.
• CakePHP's Database Interaction uses CRUD.
• CakePHP uses the test system PHPUnit.
• Is interesting in CakePHP Bake and scaffolding.

• Symfony's philosophy is each version is different.
• Symfony's is slower to learn.
• Symfony's is best for large projects.
• Symfony's Database Interaction uses Doctrine.
• Symfony's uses the test system PHPUnit.
• Is interesting in Symfony's Bundles and templates.

A big difference is in how models are created: CakePHP models are written in PHP, and Symfony models are written in YAML and powered by Propel. CakePHP's approach is more similar to ROR's ActiveRecord (although it isn't exactly an AR implementation). CakePHP, in general, is more rails-esque.

CakePHP's documentation and tools, in my opinion, have a wider target audience and the syntax and helpers are easier, but thy have yet to embrace PHP5 as their exclusive target (to autoloading isn't really there). In general, I prefer CakePHP's approach because it sort of follows an established standard, and I applaude it's organization. I'd also recommend Kohana for it's PHP5 goodness.

There's another post on stack overflow about this question, although its a bit different in focus.

Edit: I revisted Symfony to find the reasons I said 'no' and came up with these — your opinions and mileage may vary:

CakePHP also offers dead simple scaffolding and easy to understand CLI tools. Symfony's CLI syntax is a bit wonky to me, and 'CRUD' in Symfony just isn't the same. Combine that with Symfony's (awkard) action syntax and throw in Symfony's poorly designed (and challenging to understand) website, and preference for 3rd-party paid documentation (books on Amazon) and you have more ticks in the cons column.

Some of the claims about CakePHP and limitations above simply isn't true. The query is possible. You just have to know how to make it. The "automagic" of CakePHP is SUPER nice so you can hit the ground running FAST. It is BY FAR the FASTEST framework to development (hence why it's so closely modelled after RoR which obviously was a big success and buzz). There are more advanced behaviors to get data returned differently and make some of those more complex queries with a few short method calls and array parameters specified.

However. As far as I can tell, no other framework has as many "automagic" methods and classes. Cake takes the most common of tasks and provides an easy way to get it done. If you're really clever, you'll do most of your coding at the model level and make use of the app_model and app_controller file and have an extremely efficient application.

The console is great and always expanding. The community is truly amazing and there are many many contributions to help you get things rolling even faster. You can literally architect and then move "pieces" into place to build an app very quickly because most of what you'll need is available. You do not get that with any other framework. You have to spend a LOT more time coding usually.

Lastly. While the documentation was lagging, it is much better now and while Cake also got some harsh reviews during this lack of documentation and version 1.1 period...It was STILL good, just severely overlooked. With 1.2 and now Cake2 and Cake3 on the horizon...You're going to see a lot of opinions changing.

I have used CakePHP since 1.1. I'm a firm believer in it. I have used it for huge corporate sites. That receive millions and millions of hits per day...We're out of the realm of things like WordPress and Drupal for solutions. When you get to that level for a CMS type site, I am super glad to have CakePHP on it. Likewise, Symfony and CodeIgniter will help you with the scaling. I can't say anything bad about either of those frameworks either. I can only say that you will spend less time coding and find a larger community (and a super friendly IRC channel) with CakePHP.

I'm going through and documenting some of my responses to the above comments about CakePHP and some of it's (in some cases rightly) perceived faults.

Big websites are run using CakePHP, some being Mozilla Addons, Scratch by MIT, and Hot Scripts. There is a bigger list right at the bottom of the CakePHP website (http://cakephp.org). Regardless, any good developer should be able to build a scalable website using a framework as long as the framework isn't completely silly (CakePHP isn't too silly :D ).

It is true that there isn't one very good (free) CakePHP tutorial that goes through every feature of the framework, but the documentation is extremely well laid out and verbose. Anything that isn't clear can be cleared up through the Google Group and on IRC, and we welcome any and all changes/corrections to the documentation. Documentation is not just a core developer issue, as many things are application specific and people come up with interesting tips and tricks, and so thusly everyone is invited to contribute (Not just comment!). Of course it is all moderated, so most of the cruft/spam is not added.

The code is modular in that you can add in new code that supercedes core functionality. Much of the code is simply PHP classes. It is true that writing such functionality may be a burden, and I have not tried using alternate classes as fillins. Yes, it does not handle other ORMs, so you are stuck with the default, but this should be fixed in Cake3, which will be able to mix and match any other PHP classes at will (that includes Propel and Doctrine support).

The CLI is very good, and it is easy to extend for App-specific support. One example is that I recently developed a shell plugin that would automatically install any other CakePHP plugin that I have indexed from github. Took about 5 hours to build something extremely usable and flexible. I'm sure such functionality exists for Symfony, and it DOES exist for RoR :)

As for being Rails-like, it is and it isn't. Many things are similar, they are MVC frameworks after all, and CakePHP goes for the "Conventions vs Configuration" approach. PHP4 support mucks with a nicer syntax, which Symfony doubtless has because of PHP5-only support, but it is still extremely usable and intuitive. The framework does not provide EVERY feature of Rails out of the box as it isn't a straight clone. CakePHP is a framework, not a library (hi Zend), so it won't provide everything out of the box.

Generation of views is, I agree, a bit wonky in CakePHP. It is being greatly enhanced in CakePHP 1.3 and 2.0. It will support custom templates for each and every Model, View and Controller (as opposed to just a type of view as it does now). Also, there exists a set of shell tasks on github by a user going by neilcrookes that auto-bakes only certain types of views (including only admin views) which can be used in combination with custom templates to produce exactly what you want. CSS styling also helps :) but this is definitely something that can be improved.

CakePHP takes many varied parameters in it's Model::find methods, although in certain cases it may be useful to use raw SQL queries. The Model::find() method is very flexible and has not failed me insofar as creating complex finds. I suppose that is related to being comfortable with the ORM, which inevitably always takes time.

Form validation should logically be in the model layer, as that is where any action related to the database is being performed. You can specify alternate validation in a specific view I believe, or swap validations (there is a behavior for this but it wouldn't be hard to do so without it).

Multidimensional arrays are a bit silly, but you'd still likely have multidimensional objects. PHP4 had a broken Object Model and so that is why CakePHP does not use objects. This is being corrected in a future version of CakePHP (as I pointed out above in a previous comment), but it is useful to have a framework that supports PHP4 in some cases. Again, YMMV and I agree that full PHP5 will be a great boon, both in speed of the application and of development.

Databases can be swapped out at will. CakePHP does not allow functionality that is inherent in only one type of DB (hence the dropped support of ENUMs that are only in MySQL), so that the ORM is always supported and can always build valid queries. You can have multiple databases in an application, one per each Model if you wanted, and can swap them at will or even not use a database at all for a specific model. So no, it is not tied to a specific database.

In the end, your choice is your own, and I wholeheartedly suggest looking into both and reading through the documentation, checking out the Groups, IRC channels, blogs and any forums for both and seeing which framework suits your development style the best. Reader beware, I'm a CakePHP developer so my post has some bias.
