Hope is not too much OT here.

Can somebody explain me the role of gettext.dll in PHP ()

I run PHP 4.3.10 with apache 2 and extension gettext activated in PHP.ini.

However, a test with PHPESP/admin/test.php (a script that test the
functionality of GNU gettext() required for PHPESP - a PHP "program" to
buid questionnaires), fails, telling that gettext() is "emulated".

Other extensions, such as gd and mysql, do work fine.

What does "emulated" means here?

Please redirect me to the rghie group if there is one more on topic.
