metaphone

  • This function’s solution requires the text gem.

    We can calculate the metaphone key of a string in Ruby with the help of the text gem. To install this gem:

    $> sudo gem install Text
Successfully installed Text-1.1.2
1 gem installed

    Once this gem is installed, we can calculate the metaphone using

    PHP

    $result = metaphone("hello world");
var_export($result);
// => 'HLWRLT'

    To get the equivalent of the string in PHP, we need to first strip whitespace from the string.

    Ruby

    require 'rubygems'
require 'text'
 
text = "hello world".gsub(/\s/, '')
p Text::Metaphone.metaphone(text)
# => "HLWRLT"
