[Haskell-beginners] PHP vs Haskell... a challenge!

Thank you everybody for your responses, I am going to print them out and
study them hard, particularly the use of left folds. I think I skipped
that in RWH book... .I need to go back and re-cover the basic again I
think... it's a tendency of mine to graze through stuff picking up what
I need and sometimes you just can't beat learning the basics.
As a still beginner after about eight months of (somewhat intermittent)
usage I would say that in order to truly get to grips with Haskell as a
concept let alone a language you need to know and understand ...
* currying, which helped me to truly understand the signature notation
used, a -> b -> c etc. I have used haXe, which is written in ocaml, and
the notation is the same but now makes more sense!
* function composition leading to point-less notation, this is better
understood the currying penny has dropped
* lazy versus strict evaluation and the concept of lazy I/O and why it
can sometimes leave you scratching your head for a while!! LMAO! :)
* monads: of course, for me the best video I've seen is this one.
As a reluctant Drupal/PHP developer and wannabe FP developer for about
six years now, each time I find myself coding some rubbish or other in
PHP I have lots of 'ahah!' moments as I think that it would be nice to
be able to express some idiom or form more succinctly in PHP and then I
realise what X Y or Z is for in Haskell... that's the upside, the
downside is I then have to continue the job in PHP!
