When you checked uptime via telnet, were you logged in as "nobody", or
whomever PHP runs as?... If not, you haven't really duplicated the
circumstances where PHP exists.
I can't think why "nobody" wouldn'y be allowed to do "uptime", but maybe
there's some security issue involved. Too bad those load numbers aren't
right though :-)
You may have to resort to creating a suid shell script with some "real" user
as owner for PHP to be able to run it to do uptime. See "man suid" for
details.
BE CAREFUL. A mis-configured suid script is a security risk. Actually,
that's like saying a sucking chest wound is a "cut" :-^
