Are you actually running nslookup on the same physical machine that is
serving the failing php code?
I would suspect that somehow there is a configuration problem. Something
strange that they would show different results since the results should
actually be returned from the name server, not the function/program or
machine? Are both machines using the same dns server? Do both have
access to the internet?
