Questions[mkdir](server)

I am writing a PHP script for a client which will be installed on a server which I do not have back-end access to. I only have access to a particular folder and database.

My script will upload files and create folders. However I get a permission denied error when I try run mkdir() and move_uploaded_file(). Here are the conditions:

Server running IIS 6 and PHP 5.1.2 (a bad, ancient mixture, I know) Folder where I try to make a directory and upload a file has 777 permissions Folder all the way up to the web root has 777 permissions File uploads are on Uploaded file is very small, within the upload_max_filesize range Any ideas on why this isn't working?

Thank you for your time.

Ok all my files and folders are set as owner of vsftpd:nogroup. FTP program can upload and create and do everything. But when I use the PHP command mkdir, I get a Permission Denied even though the folder its creating it in is set to chmod 777. IF i set the base folder to user www-data and group www-data, PHP mkdir will work. However, I can't use FTP to delete or upload to that folder.

/uploads is base folder.

I use PHP mkdir to create a directory in there:

if (!is_dir($_SERVER['DOCUMENT_ROOT'] . "/uploads/" . $_REQUEST['clientID'] . '/video/')) {
    @mkdir($_SERVER['DOCUMENT_ROOT'] . "/uploads/" . $_REQUEST['clientID'] . '/video/', 0777);
}

If /uploads is vsftpd:nogroup then PHP mkdir will give a Permission Denied error.

If /uploads is www-data:www-data then PHP mkdir WILL work, but I cant continue to FTP anything in that folder that was just created.

If /uploads is vsftpd:www-data then PHP mkdir will give a Permission Denied error.

How can I create a directory with PHP and still be able to access it via FTP?

We're running an application on RHEL and it is trying to write a mysterious log file to a directory that doesn't exist. I'm trying to determine a find command that could go through each sub-directory in development and mkdir log without creating a recursive indefinite loop in the process. So if my folder structure from a very basic redacted view was similar to:

-dir1
--dir11
--dir12
-dir2
--dir21
--dir22
-dir3
--dir31
--dir32

I would want the end result to be

-dir1
--dir11
---log
--dir12
---log
--log
-dir2
--dir21
---log
--dir22
---log
--log
-dir3
--dir31
---log
--dir32
---log
--log

what bash command could create this structure?

for /f %d in (listfile) do md %d works for contiguous folder names (even if more than 8 characters long but not if there is a space in what will be the folder name.

Is it dangerous to have several parallel jobs create the same directory using mkdir -p? (This is under Linux.)

In my case, I send many jobs to a SUN grid to process them in parallel, and some of these jobs start by creating a certain directory foo. So, the execution of the different mkdir commands might happen at exactly the same time ...
