Remote access

I tried using :

&?php

require_once &/usr/local/cpanel/Cpanel/Accounting.php.inc&;
$host = &localhost&;
$user = &myusername&;
$accesshash = 'the long access hash here';

$accts = listaccts($host,$user,$accesshash,0);
print_r($accts);
$pkgs = listpkgs($host,$user,$accesshash,0);
print_r($pkgs);

?&
but it did not bring any output, Can anyone help?

Thanks
