Permission Hell

Anon

I'm using mkdir to create a directory

mkdir ("dir_name", "0751")

when I check the permission of the created file, I see the newly created directory as:

351 ('d-wxr-xr-x')

on the Unix command line, umask shows "22"

when I echo umask from PHP, it say "18" ??

the php scripts is creating the directory with owner "www" and group "admin" , my userid group is "staff"

when I change mkdir to:

mkdir ("dir_name", "0632")

I end up with 150 ("d--xr-x---")

no matter how I do the math, I can figure out how these permissions are being assigned.

Any help is appreciated.

PHP is probably running as "www", from the group "admin" -- ie, the PHP script is not you, so cannot create a file in your name.

You would need to chown the file, but I dont know how to do that in PHP...

Why is this a problem.. what do you need to do? If you mkdir with the right permissions, you should be able to give yourself rw access to the file/directory...

I need the script to create directories on the fly and then move files to them. From there I need to have the script delete the files in said directory at a certain point and then also delete the directory.

I'm not interested in changing the persmissions manually, this is for a web site, so I won't be logging in to change the persmission on 1000s of temp directories. PHP should be able to handle all of this by itself. All I need is for it to create directories and files with consistent permissions so that it can "symlink" files, "unlink" files, and "mkdir" directories without giving me persmission errors as it now does.

hello filmo,

the point is not to use:
mkdir ("dir_name", "0751")
but:
mkdir ("dir_name", 0751)

anyway the permissions cannot exceed
the permissions given to the directory
in which you want to create the new one.
i.e.:
imagine the serveruser is allowed to
create the new directory in bla/
its permissions are like drwxr-xr-x
- so, you couldnt say 0775
- the maximum permissions would be like
0755
OK?

Thanks Chris,

that solved the problem ...

Definitely a "duh-oo!!"

The PHP function reference showed it in quotes, so I just assumed...
