problems with chmod (operation not permitted)

[graziano]

Well I am fighting with this problem from hours .

I have a txt file which contain user data , with permission 644 and the owner is
boy boy

I am trying to add a txt line on this file using fopen but I receive permission problems .

If I try to chmod the file 777 with

chmod("$data_file",0777);

but I always receive an "Operation not permitted" error .

So , what have I do to to write a file with chmod 644 using php ?

Safe mode is disabled (off) .

since your server is the actual user running the script ("apache" or whatever your server username is), that user has to be part of the group with ownership of that file. basically, think of it this way: if you were logged into shell under the server user (not root, mind you), would you have access to chmod the file? as long as the server is part of your ownership group, you should be good to go.

understood .. ok the problem is that my php scripts run as nobody
and the script owner/group is boy .

So I have no possibility to write this file with php ?

I don't want leave this file 777 since it's dangerous .

And php 4.x ?
