rawurlencode

• In Ruby, we use the CGI class to encode a URL. We first need to require the CGI library using require "cgi". This is similar to using require_once to include a class in PHP.

  To get the closest equivalent of the result of PHP’s rawurlencode function, we’ll use the CGI.escape class method.

  The rawurlencode function in PHP encodes according to the RFC 1738 spec, and
  uses %20 to encode spaces instead of a plus (+) character. If you want to encode your URLs according to RFC 1738, you’ll need to use String#gsub to replace the + character with %20.

  PHP

  $result = rawurlencode("Hello <b>there!</b>");
  var_export($result);
  // => 'Hello%20%3Cb%3Ethere%21%3C%2Fb%3E'

  Ruby

  require 'cgi'
   
  p CGI.escape("Hello <b>there!</b>").gsub("+", "%20")
  # => "Hello%20%3Cb%3Ethere%21%3C%2Fb%3E"
