As is mentioned on CodeIgniter.com, they've set up a survey to find out more information about how PHP are using frameworks.

The anonymous survey is very brief - just seven questions - and should take no more than five minutes or so to complete. The survey is open immediately and will remain open over the weekend.

The seven questions on the survey include questions about framework usage, sets of how you feel about different framework-related topics, what editor you usually use (and for how long), how you usually interact with Git/Github. Go and voice your opinion now!
