I'm trying to write to a file in the current directory - no remote

PHP info below shows ...
Test it at:
http://home.no.net/moldevbk/fopen-test/?mode=w(write - fails)
http://home.no.net/moldevbk/fopen-test/?mode=a(append - ok)

http://home.no.net/moldevbk/fopen-test/fopen-test.phps- source code of test script.
I have searched the web and usenet, but not found this problem
mentioned before. I do realize that I can work around the problem by
truncating the file first and then appending to the empty file - but
that is ugly as ...

Just some additional information:
If I delete the file I'm trying to write to, fopen with w mode creates
the file (with owner "nobody") and no errors occurs after that.
Apperently PHP is able to write to the file when it's owned by
"nobody" with permission 644, but not when it's owned by the user
"moldevbk" with permission 666. This is something I would expect to
happen if safe mode was on, but it's not. Append mode works in both
situation. The file is also truncated by the write fopen call in both
situation.
What is going?
Hans
PS! I have contacted the hoster - I'll let you know if they have
some explanation/solution to the issue.
I have investigated this, and there is indeed a problem on our part.
The problem was introduced when we upgraded a web server, and is
caused by incompatibilities with some of the file servers. This does
not affect all of our users.
Thx for the info - I'm glad it wasn't me (or a bug in PHP).
If you want, I can move your account to a different file server. I was
about to do this anyway, but I discovered that you reference absolute
paths in your scripts. I advise you to use relative paths or at least
build the paths from $_ENV['HOME'] or similar.
Feel free to move my account - just send me an e-mail when it's done.
(If the issue is fixed this week without moving, I can wait.)
Hans
PS! I would of course prefer to use $_ENV['HOME'], but $_ENV doesn't
contain HOME because the current user is "nobody" ... The absolute
paths is set in one single file so updating is no problem.
