I build PHP applications and have yet to use a framework. However, I am greatly considering to start. I was wondering what the general opinions here about using an existing framework.
I never used to but I tend to for all but the simplest of things these days. I personally use CodeIgniter because I like how it stays out of my way.<p>Be aware though that CI tends to be looked down upon in a similar way to how PHP itself is. I like it (and it has good docs), but if you use it be prepared to be the lowest of the low :)
We CakePHP on our flagship product, which is a government level enterprise application.<p>I used to use codeigniter, but there are too many things that (in my opinion) should be done for you, that you have to do yourself.<p>Codeigniter is a great first framework also. Much easier to pick up than CakePHP, or Zend.
I'd definitely recommend CodeIgniter with the Data Mapper ORM, I've tried others (Cake, Zend, etc) and CI seems to be the only one that never over-complicates things.<p>For me it's about getting shit done, I'm too busy to worry about being looked down on by Zend users :)
Existing frameworks remove a lot of the problems that come with attempting to roll your own code all the time. From security to just making things simpler.<p>I would suggest usually using a framework when you can.
I always use either a framework or a CMS that's a framework, like Wordpress with Thematic. Every time I get involved in a project that has no framework (and too low of a budget) I regret it.
So far we have 1 recommendation to use a framework, and 1 recommendation to use KohanaPHP IF you choose to use a framework. Any other recommendations or thoughts?
