Using a php variable with javascript?

Hi,

I'm following a book about php sessions. So I've set myself up to the point where a user on my system can login and is served a page that looks like this:

<?php

session_start();
$username = $HTTP_POST_VARS['username'];
$password = $HTTP_POST_VARS['password'];
?>

Ok so that is great, now the page loads and knows the logged in username and password. I have some javascript functions that need to know the username though at some point:

<script>
var strCurrUserName = $username;
var vParams = strCurrUserName + "," + "something good";
httpAjaxRequest.open("GET", url + vParams, true);
</script>

How can we do that?

Thanks

This question was for 500 points, may I ask one more related question that is also pretty simple? I'm using some AJAX in my script, but the php function I'm calling always returns an extra space character:

<?php
echo "Hello!";
?>

<script>

function waitForAjaxResponse()
{
if (httpResponse.readyState == 4) {
alert("[" + httpResponse.text + "]");
}
}

And the alert box always says:

"[ Hello!]"

Any ideas why the heck I'm always getting that extra space character in there?

Thanks
