mkdir($name, 0777) results in 755 permissions

This is in an account (shared server) on Pair Networks. When I use PHP to create a directory using mkdir and specify 777 permissions, the created directories are 755.

Never had a problem with this (the permissions being 755) until yesterday, when suddenly I couldn't upload images to, or change permissions of, some directories that had been created using PHP. Pair told me the directories were owned by "nobody" and that I should run PHP under something called php-cgiwrap, which would make the owner me instead of nobody.

That makes me nervous, especially for an otherwise mature content management system. I'd hate to break or slow down a lot of other things. Plus these directories were writeable by the CMS until - well - yesterday anyway.

Can't understand what could have changed - seemingly spontaneously. Or why the permissions I set when creating via PHP aren't actually set for the directories.

Perhaps someone with more knowledge about all this can enlighten me...

I had this happen to me at work. I was working with Magento and looking at the image uploader for products and realizing that folders were being created as "nobody". My problem was that the actual Apache server was on one box while the files being served were on my local machine. So Apache was creating folders under a user that wasn't on my machine (www-data).

Something to think about is using [man]umask/man and setting it to 0 to see if that will create the folders in 777 mode. Not sure precisely where you could track it down. I would pull the code you have running out for a second into a test script and strip it down to just a very basic mkdir() call. Then inspect the results. I'd then add code back in to see what could be causing it.

I never did find the issue, so I just had to deal with it; however, if worse comes to worse, you could create your own mkdir function which calls mkdir, then chmod, then chown.

On the other hand....

Running PHP in cgi mode isn't going to kill your server; however, it may run slower than normal. How much slower depends upon precisely how much load the server is getting.

Sorry I can't be of more help.
