If you look at the source of the page in your browser (with your first attempt), you see:

<script>
 var t = test
</script>

And from here, you could guess what's amiss.

<?php
    echo "<script type='text/javascript'>var t = '$v';</script>";
?>

Javascript runs clientside and php runs server side so you can't just pass one straight through to the other - they don't run at the same time. You can use php to create javascript to run later though.
