ucwords

The ucwords() function turns the first character of each word in a string to upper-case, if the first character is alphabetic.

PHP

echo ucwords("ruby is easy.");
=> // Ruby Is Easy.

Ruby doesn’t have a function which can capitalize all the words in a string - so to accomplish this it’s a little bit harder. You need to split the string into words, then capitalize the first character of each word, and then finally join all the words back into a string.

Ruby

puts "ruby is easy.".split(' ').select {|w| w.capitalize! || w }.join(' ');
=> # Ruby Is Easy.
