PHP :: Flash - How To Capture Textarea With Linebreaks

I'm trying to experiment with taking text from a textarea in a flex project and open it up in a php page. But the php isn't line breaking where it should be. An Example of the text i'd like to bring over to php would be:

You: Hi there
Them: Hello
You: This is a great example
Them: I know right?

Here's my php:
<?php
$text= $_GET['text'];
echo $text;
?>

Right now I came up with something like this in the actionscript...
var chatBox:String=chat_box.text;
navigateToURL(new URLRequest("savelog.php?text="+chatBox), '_blank');

I also tried something like:
var chatBox:String=chat_box.text.valueOf().replace("
","<br/>");
and
var chatBox:String=chat_box.text.toString().valueOf().replace("
","<br/>");

But apparently the isn't translating over no matter how I get the chatBox var so its not even making a <br/>. But, even if i did get that to work it wouldnt be ideal. Because eventually in the end I want to be able to just incorporate the pastebin API to paste this GET data and post it on there. And I don't think it would look too pretty with having <br/> after every line...Is it possible to bring this text over to php and recognize the line breaks in a way that would work well with what im eventually trying to accomplish?
