Does php support gettext web server support?

Question

I am trying to use Apache on Ubuntu 14.04 and it works fine:

<?php
// Set language to Polish
var_dump(setlocale(LC_ALL, 'pl_PL.UTF8'));

echo file_get_contents('/var/www/app/backend/gettext/locale/pl_PL/LC_MESSAGES/app.mo');

// Specify location of translation tables
var_dump(bindtextdomain("app", "/var/www/app/backend/gettext/locale"));

var_dump(bind_textdomain_codeset("app", 'UTF-8'));

// Choose domain
var_dump(textdomain("app"));

echo _('I want translate this!');
echo _('This to!');

But when I try this on PHP built on a web server, I only get the English version and that is the only difference between the two. Is gettext php built into the web server supported? Any way around this?

Thanks for the help!
