fwrite Permission variations from server to server in PHP Coding Help Posted October 5, 2011 (This might be the wrong forum; it might be server-side configuration, but alas it is the code that *calls* fwrite, so I'll start here.) I have written a script, and one thing it does is generate a file to disk using fwrite. No big deal. Here's what interests me: On most servers, the file is written successfully when the folder's permissions are 755 with recursive permissions. On some servers, 755 fails. Only 777 works. How could this be? Are permissions=permissions=permissions? Why will 755 work on one machine but not another? I'm just a logic guy; I know very little of server-side configuration and/or why there would be a difference here. Just trying to learn.
