Hi guys..

Lately i've been try so hard convincing company to use open source such PHP.
They are so hard to accept that PHP is a great thing, they only believe in payable things, majority from Microsoft of course. So they dare me to do a presentation why Opensource is better than the payable things, is it secure?safe?worthy?bla..bla..bla..So right now i need help from all of you,where i can get a complete article or information,complete with the comparison between PHP or Opensource world and the payable MS stuffs.
I really dont have much time and i need your help.
i think php.net dont cover all information to brief the managers as it full of theory...
