I'm trying to get some statistics about how most PHP sites are configured, specifically what extensions are installed on them.

I'm particularly interested in knowing if Mcrypt is installed or not.

Anyone know of any sites collating such information?

I'm interested in this too, for the mb_string extension especially :) – Alex Sep 22 '11 at 16:09
Is the question : "what percentage of php instances from providers give you access to this extension ?" or "what percentage of php instaces have Mcrypt enabled ?". If the question if the first, you can have your answer quite easily, just do it by hosting provider / number of instances served, I'm pretty sure you can cover the top providers quickly. I can see sites collating the info about hosting providers - not about specific individual PHP instances (which are a minority anyway). – Morg. Sep 29 '11 at 9:58
