does php interpret the file or not?
you can decide it if you request the css file directly with a browser.
if you see <?php and code in it, it is not interpreted.
a possible solution for that:
"Use .htaccess to force your .css files to *really* be PHP files:
<Files ~.css>
ForceType application/x-httpd-php
</Files>"
(quoted from Richard Lynch's earlier post)
another problem may be if you do not send correct content-type header.
the first line should be something like
<?php header('Content-type: text/css'); ?>
before the css stuff.
hope that helps
