Description:
------------
The recursive option of mkdir() creates wrong owners for created parents.







Reproduce code:
---------------
Executed file:
-rw-rw-rw- 1 thisuser mygoup  5900 Jun 28 09:32 test.php

saveLocation:
/mnt/shared/

ls -al /mnt/shared/
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 .
drwxr-xr-x 5 root     root     4096 Jun 23 15:11 ..
(note: server is MS Windows 2000 server, executing server is Fedora Core 5. 'thisuser' has read/write permissions on server as well)

Code:
$saveLocation = /mnt/shared/1/2/3/
if (!file_exists($saveLocation) && !is_dir($saveLocation)) mkdir($saveLocation,0777,true);



Expected result:
----------------
ls -al /mnt/shared/
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 .
drwxr-xr-x 5 root     root     4096 Jun 23 15:11 ..
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 1

ls -al /mnt/shared/1/
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 .
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 ..
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 2

ls -al /mnt/shared/1/2/
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 .
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 ..
drwxrwxrwx 1 thisuser mygroup     0 Jun 28 09:21 3


Actual result:
--------------
ls -al /mnt/shared/
drwxrwxrwx 1 thisuser  mygroup    0 Jun 28  2006 .
drwxr-xr-x 5 root         root 4096 Jun 23 15:11 ..
drwxrwxrwx 1 root         root    0 Jun 28  2006 1

ls -al /mnt/shared/1/
drwxrwxrwx 1 root         root    0 Jun 28  2006 .
drwxrwxrwx 1 thisuser  mygroup    0 Jun 28  2006 ..

Errorlog:
[Wed Jun 28 10:58:43 2006] [error] [client xx.xx.xx.xx] PHP Warning:  mkdir() [<a href='function.mkdir'>function.mkdir</a>]: Permission denied in /var/www/html/test.php on line 2, referer: http://xx.xx.xx.xx/test.php

When I execute the same script again, it will create another directory (2), but exits with the same error.

mkdir() has nothing to do with the permissions, it just creates directories.
Not PHP problem.

why does mkdir() create the first dir (1), failes to make the others, when recursive=true?
 [2006-06-29 21:28 UTC] oscar dot de dot lathouder at gmail dot com 
I'm not sure about the 'standard owner' created by PHP(which is 'root'), but the solution was found in using umask().

<?php
$saveLocation= "/testdir/test1/test2/test4";
if (!is_dir($saveLocation)){
        $oldumask = umask(0);
        mkdir($saveLocation,0666,true);
        umask($oldumask);
}
?>

Sorry.
