最佳实践：在JavaScript代码中包含PHP

I'm a PHP phr34k addicted to JavaScript on the quest for some knowledge. If one were to include php code in their scripts, what would be the best method? I have provided some sample code as an example on how I would go about including PHP in my scripts.

Is this a valid method?

index.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>PHP with JavaScript?</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="test.js.php"></script>
</head>
<body>
</body>
</html>

test.js.php

<?php 

$foo = 'bar';

?>

$(document).ready(function() {
    var foo = '<?php echo $foo; ?>';
    alert(foo);
});

Thanks again!

    Also set the content type header in test.js.php

    header('Content-Type: text/javascript');

    You can also define foo inline like

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>PHP with JavaScript?</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
    var foo = '<?php echo $foo;?>';
</script>
<script type="text/javascript" src="test.js"></script>
</head>
<body>
</body>
</html>

    test.js 

    $(function(){
    alert(foo);
});
