I have a nice plugin idea I'm working on, but I also need to get a list from my WordPress installation first to even begin.
Here's the thing, I need an associative array of function names with a value of the version they were implemented. Now I already have used phpXref to dump 3.3.1's output to my files, but that's not what I want to work with for this project.
I want to implement a PHP script that would check each and every PHP file inside the current WordPress installation within some sort of for.. or while.. loop. I have that much figured out, I just need to get the @since parameter and it's corresponding function.
