I've written a tutorial/review on ruby blocks and closures with code examples, be sure to check it out: ruby blocks and closures

PHP minimal version:
echo implode(“,”, $fruits = array(‘apple’,'banana’,'orange’)); echo end($fruits);

The MIM — Wed, 16 Sep 2009 15:42:27 +0000

minimal version: f = nil ['apple', 'bannana', 'orange'].each {|f| print "#{f}, "}; puts f

fruit = %w[apple banana orange]
string = fruit.join(‘, ‘)
puts “#{string}, #{fruit.last}”

But I’ve found some other solution for this:

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.
