Well, array_walk() lets you use a callback function to treat your data,
which is a totally different approach to the structure of your script;
whereas yes, it's always possible (I guess) to do things with 'classic'
loops.
I don't pretend, it remains a good question; but IMO there isn't any
deeper reasoning behind it.
Anyway, concerning your doubts about what to use and when, I recently
found some really good reading here:

I don't know if it answers your question correctly, but you should take
a look, it's worth it ;).
