ActionScript 3.0 :: Socket Not Connecting Outside Of Flash?

I was just doing some testing using PHP sockets and Flash. I used several things, one thing is this tutorial:I have the server running, and when I run the swf via Flash it connects fine. But when I run it from the browser it can't connect.. Because that Tutorial is in AS2, I also wrote a quick client to connect with AS3, but I'm having the exact same problem.. it only connects if I run it through flash.Here's an example of the basic code:

Code:
var s:Socket = new Socket('my IP', 5445);
s.addEventListener(ProgressEvent.SOCKET_DATA, getData);
