The first version was hard coded to the desired result.
What if, "out of the blue", you wanted to reverse the final table:

instead of you'd like

name bio psych chem grade joe jill john
joe a - - bio a - -
jill - a b psych - a b
john - b a chem - b a


If you got stuck with the simple version you'd have to change it (and
lose the original) or (worse???) make a copy to do about exactly the
same thing.

With the new version, just change the parameters to the function :)

Thank you.

That's a valid point of vue :)
I tend to try and make functions (the ones I think deserve it) work for
everything you can throw at them.


If I need to make a pivot table next month about something, I just
include "pivot.php" and call the function. Hopefully it will work just
like expected on the first run.

As it stands now, it just needs a bit (a lot) more documentation, either
in comments or in a separate file.
