@NogDogJan 25.2005 — #chmod will only work if either (a) you are the owner of the file being changed, or (b) you are the root "superuser". When you run a PHP page via the webserver, the process is normally run under its own user ID, [i]not[/i] your user ID.
One way to deal with this would be to have your sysadmin add you to the same user group that the PHP user belongs to. Then set the permissions on the directory and any files to include read/write for the owner and the group: 664. You may want to change your umask to 002 as well, to make the default permissions include write for the group. (Again, see your sysadmin to help set this up.)@NogDogJan 26.2005 — #umask tells the OS what default permissions should be assigned to newly created files. (Note: I'm not really an expert on this sort of stuff - I would talk with a sysadmin type to help me set this kind of stuff up if I were in your place. I just know enough to be dangerous. ? )
change chmod for overwriting files on remote server
I have set up a folder for uploading images.I want to overwrite some of the images,as and when required.I changed the permissions of the folder on my host to 777 using WS-FTP and then using chmod.
The permission reverts back to 644 and the file does not get overwritten.Is there any PHP script to use to change the permissions?Can anyone tell me what to do.???If I try to change it again,then I am getting ‘550’ “permission denied” .Is there some restriction put by the administrator?
