Comment on array_change_key_case by Boris Barroso

hash = {’FirSt’ => 1, ‘SecOnd’ => 4}
p Hash[hash.keys.map(&:upcase).zip(hash.values)]
# => {”FIRST”=>1, “SECOND”=>4}

Another way
p1 = ['python', 'lisp', 'perl']
p2 = ['PY', 'LI', 'PE']
Hash[p1.zip(p2)]

RUBY:

puts ‘There are %d monkeys in the %s’ % [5, 'tree']

This is what you would do if you want to flip a Ruby array into a Ruby hash:

a = ["apple", "orange", "banana"]
flipped = {}
a.each_with_index { |e, i| flipped[e] = i }

p flipped
=> {”apple”=>0, “orange”=>1, “banana”=>2}

With a hash

a = {}
5.times{|i| a[i+3] = ‘php’}
puts a
# => {3=>”php”, 4=>”php”, 5=>”php”, 6=>”php”, 7=>”php”}

Why the bleep is this so complicated?
Try this:

result = {}
keys.each{|k| result[k] = ‘code’}

hey my comment went corrupted!

I wanted to add in the two class fields:

[in php]
if($cond) echo ‘myclass’;

[in ruby]
concat ‘myclass’ if cond

I think “concat” is actually the real conversion for “echo”.

Please consider the following:

…

The converted:

…

“puts” and “print” are -if i’m not wrong- for background usage (eg. terminal, logs, file, …)

When you’re merging arrays with different keys you can also use “+” in PHP:

$user = $user_details + $account_details;

the point of this function is to create
