array_fill_keys

  • This function’s solution uses a Ruby Hash object since Ruby arrays don’t use associative key/value pairs. See Array for more details.

    There is no direct equivalent of the array_fill_keys method in Ruby. We can achieve the same results by building a new hash from existing array information using the Enumerable#inject method.

    PHP

    $keys = array('peel', 'eat');
    $result = array_fill_keys($keys, 'orange');
    var_export($result);
    // => array('peel' => 'orange', 'eat' => 'orange')

    Ruby

    keys = ['peel', 'eat']
    result = keys.inject({}) do |hash, key| 
      hash[key] = 'orange'
      hash 
    end
    p result
    # => {"eat"=>"orange", "peel"=>"orange"}
