To anyone reading comp.lang.php - sorry reposting here.
I'm trying to write to a file in the current directory (which has been
uploaded by FTP, not created by PHP) - no remote files involved. The
subject says it all - I can add that both the directory and the file
is world-writable. This happens on a (quite good) free hoster in Norway
which doesn't use safe mode, running PHP 5.1.6 as the 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/p.php - PHP info
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 ...
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", the webserver user, but not when it's owned by the user
"moldevbk" even if the 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.)
What is going? How can fopen truncate the file, but not being able to
write any content to it?
Hans
