chmod chown problems

[Anon]

have I got this in the correct forum this time ;-)

Hi guys I hope you can help me with this:

When I run the below code on my server I get the following errors:

---

Warning: chown failed: Operation not permitted in /home/virtual/battlegrounds/home/httpd/html/mistbook/create.php on line 13

Warning: chmod failed: Operation not permitted in /home/virtual/battlegrounds/home/httpd/html/mistbook/create.php on line 14

As far as I can tell the code is correct and should work, however if I'm getting "failed" does this indicate that something on my hosts server has been set to not allow me to do this?

Is there any reason that these functions should be disabled?

---

$info = "some text to go in the file"
$whatfile = fopen("file.dat", "w");
fwrite($whatfile, $info);
fclose($whatfile);
chown("file.dat", "newowner");
chmod("file.dat", 0777);

"Warning: chown failed: Operation not permitted "

many hosts dont allow chown - try in SSH and see if you get the same message if not try

exec('chown somefile.file someone someone');

Only a superuser can chown (usually root). Your scripts (if PHP is an apache mod) are running as user nobody or apache.

It it not advisable to give apache superuser permissions. You really don't want apache to be able to chown.
