Hello Nogdog,
Well, I been reading a lot about it because is a world I really want to learn and most sites that compare different frameworks that I been reading and it gets to the comparason of Symfony and Zend to be the best. The Frameworks that I been reading about are the major ones on my opinion those are CakePhp, CodeIgniter, Yii, Symfony and Zend.
CodeIgniter they sayed is really good as you said is easy to learn that for me that is a big plus since I am a newbie on the subject but, the problem with CI is that is not trustfull to use in a big project like for example a dating site like matchdotcom it is more suitable to use it to build blogs, forums or projects that you do not have a lot of users with a lot of features to manage like a social network or dating site for example.
Cakephp it seems that is suitable for that kind of projects and the plus it has that has a great community and a lot of projects prebaked as they called but, personally I just seem the process of building something in Cakephp was very difficult and did not make sense to me all the bakery process.
Then there is Yii people been talking a lot about it and it seems very interesting because a lot of people said that is better than Zend or Symfony since its not as hard to learn, also the community is great, there not as many Yii developers as Zend or Symfony, also it saves a lot of time and its really robust for larger projects.
Symfony has an awesome fame after Yahoo announce it uses symfony for del.icio.us, Yahoo Answers and Yahoo Bookmarks, that really put them upthere most symfony developers are completely safisfied with the framework but, the problem with it that is very slow with small projects, its great for large projects like Yahoo but, not for small things and also, people said it is very dificult for a newbie to make sense to it.
Zend Framework is like the main framework on the PHP world or its been seeing that way because its the same company that build PHP language what it is today, also there are tons of developers for Zend, there even certificacions from Zend for developers, a lot of large projects are done on Zend, has great documentation and a a great community for support.
After you asking me this I went and took another look and I think i just decide what to choose not Zend or Symfony I think I feel more attract for Yii, has a lot of great reviews from newbies and experience developers that are happy with it. If anyone can recommend me a book to read and learn Yii I will appreciate or tutorials and also give me his/her opinion of Yii.
Thanks for helping me decide which to use.
