how to reboot vyatta pc router via php?

[torres]

i used vyatta pc router (linux based) and i have installed XAMPP for Linux 1.6.6 web server on my router. I would like to know how to reboot my vyatta via php script... I've tried to do that. Here's the scrpit :
/opt/lampp/htdocs/webvy/reboot.php
<?php
exec (/user/bin/sudo /sbin/reboot);
?>

/opt/lampp/htdocs/webvy/form-reboot.html
<a href="reboot.php">Reboot</a>

/etc/sudoers
apache ALL=/sbin/reboot,/opt/lampp/htdocs/webvy/reboot.php NOPASSWD

My script doesn't work and contain an error in /opt/lampp/logs/error_log :
password :
anybody know what's wrong with my script???

Is Apache really running as the user apache, or is it maybe a different user?
