fopen/fwrite and owner/group settings

How to change the owner/group?

[BlackDex]

Hello there,

I Have a problem with some file writeing.

I Use fopen to create a new file, but that file gets the owner and group the same as the apache owner and group.

How can i change it so that the file gets the same owner/group as the files i upload with FTP?

If you think this post belongs to apache then please move this post :).

Thx in advanced,

Why would you want to change the owner/group to the FTP user? Why not keep it as the user that uploaded the file?

Um....

That is what i mend :p

I think i just fraised it wrong..

I Want the owner of the file to be the owner when it gets executed.

And that isn't the way it is now.

exec("chown newowner /path/to/the/file.jpg");

If you do not run your own server
check with your ISP

Quite a few ISPs won't allow you to change ownership

Well...
chown doesn't work...
Only root can change owners (atleast on our server).
But owners can change groups.

Anway..

The only solution i can find is to use suExec or something like that.
But that means i have to use CGI, and then the perferonase goes down.

Is there an other solution for this problem?

Thx in advanced.

But owners can change groups.

Then how about chgrp [php.net]?

[BlackDex]

chgrp is fine, if you want to let the group have write access.
But on a server with multiple hosts this just isn't secure.

i Mabye have found a create tool that works just like suExec for CGI scripts.

Thisone is called suPHP [suphp.org], this together with Safe_Mode should do the trick of what i want :).

It will start the script using the owner/group of the script, and therefor every file created by that script will be of the same owner/group.

I haven't tryed it yet, but i have seen some good posts about it.
