File Permissions

[ericgodfrey]

So I just had a few problems, that turned out to be file permissions stuff. Under the updated server configuration, files with 664 permisions and folders with 775 permissions no longer worked. (Premature header error. Really annoying)

So I don't have a problem with that, and I'm sure it has something to do with security, but I would appreciate if someone explained how they worked, or pointed me towards a resource or two. Thanks.

You are on a shared server and the shared servers are running phpsuexec or suPHP. Both doesn't allow any world writable files/folders. You should set the file permissions to 644 and the folders to 755 and all will work fine.

phpsuexec and suPHP both allow PHP to run scripts under your user id instead of "nobody." Therefore files are accessed as if your were accessing them from FTP or and SSH session and new files are created with you as the owner. You don't need anything world writable anymore, so since world-writable files can be a big security weakness, both phpsuexec and suPHP check for and refuse to access anything that is world writable.
