Gettext fails me

[redhog]

I can not get gettext to work at all under PHP. I run ubuntu 6.06.1
LTS, and the php5 package there announces that it supports gettext.
Also, php -i sais gettext GetText Support =enabled, so it should be
working. Here follows a minimal example that should be working, but
isn't (gettext and msgfmt are the normal GNU gettext tools):

[redhog@thalari: ~/Projects/DemoWave]$ cat foo.php
#! /usr/bin/php
<?php
bindtextdomain( $argv[1], $_ENV['TEXTDOMAINDIR']);
echo dgettext($argv[1], $argv[2]);
?>
[redhog@thalari: ~/Projects/DemoWave]$ cat

Could someone please help?
Thanks in advance,
