A few fun and useless facts I collected while mining through 54 WordPress releases, from 0.7.1 to 3.0.1:

  • The latest version of WordPress, 3.0.1 as of publishing, has 3240 PHP functions defined.
  • The first version (0.7.1) had 309
  • Across all WordPress versions, 3920 PHP functions have been defined and used
  • On average, each ".X" release (2.1, 2.9…) introduces 225,2 new functions
  • Only one release went on a diet: version 1.2.1 had 23 functions less than its predecessor, version 1.0.2

Have a look at my Excel mad skillz showing the evolution of the total number of functions defined in WordPress:

The following graphs shows how many functions have been added (ie functions added minus functions removed) in each version.

To my surprise, the biggest evolution has been in WordPress 2.8 ; I would have predicted that the inclusion of multisite functions in 3.0 would have a larger impact.

For the curious and nitpickers: data sheet used.
