use Rack::Legacy::Php, Dir.getwd
use Rack::Legacy::Cgi, Dir.getwd
run Rack::File.new Dir.getwd

Im getting the following error

NoMethodError: undefined method `script_path' for #<Rack::Legacy::Php:0x007ff9dc155a30>

any ideas?

My guess is that since that was written against Rack::Legacy v.0.2.1, that function has been removed since then. I ended up uninstalling pow due to difficulties with RVM, so I'm afraid I won't be much help.

No problem man, thanks though. I actually just dropped rvm and started using rbenv, might wanna give that go. I love the ease of use of pow.

this does the trick:

module Rack
  module Legacy
    class Php
      def run(env, path)
        config = {'cgi.force_redirect' => 0}
        config.merge! HtAccess.merge_all(path, public_dir) if @htaccess_enabled
        config = config.collect {|(key, value)| "#{key}=#{value}"}
        config.collect! {|kv| ['-d', kv]}

        script, info = *path_parts(path)
        env['SCRIPT_FILENAME'] = script
        env['SCRIPT_NAME'] = strip_public script
        env['PATH_INFO'] = info
        env['REQUEST_URI'] = strip_public path
        env['REQUEST_URI'] = env['POW_ORIGINAL_REQUEST'] unless env['POW_ORIGINAL_REQUEST'].nil?
        super env, @php_exe, *config.flatten
      end
    end
  end
end
