ucwords

  • Ruby does not have a built-in method to capitalize all of the words within a string. We can accomplish this using the following example:

    1. String#split the string into individual words
    2. Enumerable#select to iterate through the words
    3. String#capitalize! each word
    4. Array#join the words back into a single string

    PHP

    print ucwords("hello world");
// => Hello World

    Ruby

    "hello world".split(' ').select {|w| w.capitalize! || w }.join(' ')
# => Hello World

    Rails includes a built in String#titleize method as part of ActiveSupport library. This will perform the equivalent of the above Ruby.

    Rails

    "hello world".titleize
# => Hello World
