It is weird that it would work in the admin interface, if that is
running in the exact same instance of your server. Might indeed be a
PHP problem. Can you try doing a lookup from the cmdline (with dig)
when it fails in PHP to see if everything resolves correctly?

The contents of /etc/nsswitch.conf might be interesting too.
