fruit = %w[apple banana orange]
last_fruit = nil

fruit.each do |f|
print “#{f}, ”
last_fruit = f
end

print last_fruit

which would be near php method:

fruits = %w[apple banana orange]
fruit = nil

fruits.each do |fruit|
print “#{fruit}, ”
end

print fruit

It’s nicer than method with “last_fruit”. But it’s only a hint.

“Dynamic scoping” has a very specific meaning. PHP appears to use dynamic scoping; Ruby uses lexical scoping, not dynamic scoping.

I’m not sure what you mean by “more dynamic”. If you mean the dictionary definition (roughly, “energetic”), I’m not sure how that applies. If you mean the computer science definition, it sounds exactly backwards.
