Enabling Sybase on PHP5 in WIndows

Hello all, I've recently installed Sybase ASE15 Express on a Linux installation on VMWare. Now, I'd like to connect through PHP to the Sybase database server. So, after searching a bit I read that I needed to install the Sybase Open Client. Installed that, it connected fine through Sybase Central, but PHP still refused to load the php_sybase_ct.dll. It's in the folder all my other extentsions are in. Yet when I start Apache I get an error that PHP couldn't load php_sybase_ct.dll. Any idea on how to enable this? I'd try ODBC, but that's just messy in my opinion when you should be able to use the Sybase library. Thanks, Ben
