            loader.load(request);

            function _urlSended(e:Event){
            var loader:URLLoader = URLLoader(e.target);
            return loader.data;                     
            }
        }

A few things - firstly, we generally reserve Uppercase variables for Class names in AS.

The problem with your code is that you set up a listener and respond to that listener within the same block. You are attempting to return data back to the listener, as it was the calling object, but listener objects have no way of handling it. So make another function, and deal with your data outside of function login:

private var _loader:URLLoader;
public function login(username:String, password:String){
            _loader = new URLLoader();
            var request:URLRequest = new URLRequest('http://localhost/hosting/index.php');

            request.method = URLRequestMethod.POST;
            var variables:URLVariables = new URLVariables();
            variables.username = username;
            variables.password = password;
            request.data = variables;

            //handlers
            _loader.addEventListener(Event.COMPLETE, urlSended);
            _loader.load(request);
        }

private function urlSended(e:Event):void{
    var data:String = _loader.data;  //e.data may work?

    // now do something with it---
}

First off you cannot return stuff from an event handler.

Secondly, you shouldn't have a function within a function. It may work but it is a bad practice.

I suggest you trigger another method with and send loader.data along with it. Either that or do what you to do with loader.data inside your _urlSended function
