UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? What happens when I CHMod a file to 444 (read/read/read)?

Dave, a banner rotation script that I want to implement uses a simple text file to pull banner codes from. I just don't want someone to be able to change that file to then inject funny code into the header.

Just wondering what I should chmod that file to. Or maybe leave it at 644?

So what happens if I make it 444? Will I still be able to erase the file using ftp?
