Get page contents with PHP+CURL

I need to get the content from the site [login to view URL] using PHP. This page has no captcha, but there is a security system and need to be logged. To register user access: [login to view URL] You can logged using facebook or direct. I'll pay US$ 40,00 to first one who can do this. There is a file attached, that could be the security system js file. Another freelancer tried with no sucess and wrote this: - ok, but [login to view URL] is some harder than just php+curl, because it validates every request with a javascript function, if you can get someone to translate it from javascript to php, I'll send you the code to translate. - yes it works. It's a kind of challenge, with a set of values from the server generates a string code to send with all the rest of the data. - I'm not sure, but in every you request you get the javascript as response. It submits a generated code and then shows the content. It's possible to emulate the generated code, but it's necessary to translate the javascript to php. - I added a comment in the file. I don't how the code is generated, once having that, the rest is no problem.
