Douglas Brown is running a poll in a new post to his blog asking which of the six choices (of the major PHP frameworks) is your favorite PHP framework.
In a perfect world, I would suggest to learn them all! However, there are only 24 hours in a day, and prioritizing your PHP framework education might be a good idea. So above I added a poll that I plead to other PHP developers out there to vote on. Hopefully after a lot of participation we will see the most popular PHP framework.
His motivation is to provide a good resource to developers looking to choose a framework and wanting to find one of the best supported and most used choices. He also solicits comments on the post if you have opinions on why one framework shines above the rest.
