Hi guys,
I am working on script that will assemble data to create a page and have
come to an interesting conclusion. Its a perfect fit for recursion as
part 1 of the doc will require additional parts and so on.
I wrote it at first with two loops. The first loop gathered data and
the second arranged the data.
For completeness sake, I rewrote it using recursion where I have a
get_data() function that is called within itself if said data needs more
data.
The results were quite suprising. I get about a 80% increase in speed
(using openload with 20 concurrents to test) using the recursion. Now,
at most, I will be recursing 4 or 5 levels deep.
Does PHP optimize recursion in such a way that this is expected or did I
get lucky and I may hit a wall when I am not looking?
