maile excell som vedhæftet fil fra debiansrv

Hej alle jer eksperter. Jeg har nu siddet og rodet med at få vedhæftet fil fra excell der er uploaded til min debian.
Jeg bruger et script, tror det er fra zend...
Upload delen har jeg på plads. Ønkser f.eks at vedhæfte filen /home/bruger/data/regneark.xls
Kan nogen vise med et eks. hvordan filen vedhæftes.
Her følger scriptet:
<?php
// smtp_client class -------------------------------------------------------
// use:
//        $smtp=smtp_client();
//        $smtp->email($from, $to[0], $to_name[0], $header[0], $subject[0], $body[0]);
//        $smtp->email($from, $to[1], $to_name[1], $header[1], $subject[1], $body[1]);
//        $smtp->send();
