rawurldecode

  • In Ruby, we use the CGI class to decode 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 equivalent result of PHP’s rawurldecode function, we’ll use the CGI.unescape class method.

    PHP

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

    Ruby

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