create_function

  • Creating lambda style anonymous methods in Ruby is very convenient with the help of Ruby blocks. We create an anonymous method in Ruby by passing a block to the Kernel#lamda method. This will result in a Proc object instance. While PHP’s create_function takes strings as arguments, the arguments and code for an anonymous function in Ruby are specified as block arguments, and the block body respectively.

    We can execute an anonymous method in Ruby using Proc#call on our anonymous method.

    PHP

    $add = create_function('$num1,$num2', 'return $num1 + $num2;');
print $add(2, 3);
// => 5

    Ruby

    add = lambda do |num1, num2|
  num1 + num2
end
 
p add.call(2, 3)
# => 5
