MAJOR AMF3 AMFPHP NetConnection BUG in AS3

If anyone is using my phpRemoting package, be aware there is a serious bug in AS3's AMF3 implementation and you need to switch the code in the phpAccess file to AMF0.

Here's what's up: The AMF3 encoder is fine sending an array out, and fine receiving a MySQL result set as an object. But if you try to send an array and receive a MySQL result in the same call, the result comes in as null.

Simple example:

Code:

---

var rs:NetConnection = new NetConnection();

/*uncommenting the following line makes the PHP request return an object. When it is commented, i.e. using AMF3, the PHP request returns null.*/

//rs.objectEncoding = flash.net.ObjectEncoding.AMF0;

rs.connect("http://localhost/~strike/barkNet/barknetamfphp/gateway.php");
var rsResponder:Responder = new Responder(gotResult, handleError);

var v:Array = new Array("a","b","c");
rs.call("genericEvent.arrayTest",rsResponder,v);

function gotResult(re:Object) {
        trace (re); //returns Object under AMF0, null under AMF3
}
function handleError(fe:Object) {
}

---

Note that this has NOTHING to do with the PHP code being run. In fact, the PHP code is just this:

Code:

---

        function arrayTest($arr) {
                $q = "SELECT * FROM users";
                $z = mysql_query($q);
                return ($z);
        }

---

Interestingly, if you have the code return $arr, you actually get the array right back under AMF3.

This is a dirty filthy bug that cost me a lot of time and money. BEWARE.
