mkdir() permission unaltered

Question

I am creating a image upload functionality using php.

I was working on Windows using vagrant and everything worked fine. Now, I moved to Ubuntu (still using vagrant) and the script does not work anymore.

I create two folders, before I upload the image and just the first one is created at the moment.

$folder_name = Config::get('PATH_IMAGES') . Session::get('user_id') . '/';
$profile_folder = $folder_name . 'profile/';

// create a folder for the user's images
if (!(is_dir($folder_name) || is_writable($folder_name))) {
    mkdir($folder_name, 0777);
}           

if (!(is_dir($profile_folder) || is_writable($profile_folder))) {
    mkdir($profile_folder, 0777, true);
}

This creates one folder with the following permissions:

drwxrwxr-x 2 user user 4096 Aug 9 21.33 folder_name

Not drwxrwxrwx!

Now, if I change the permissions manually (chmod -R 777 folder_name), I get the following:

drwxrwxrwx 2 user user 4096 Aug 9 21.33 folder_name

Running my script again, will create the second directory. Repeating this process with the second directory I am able to finally upload the image.

What I tried so far:

$folder_name = Config::get('PATH_IMAGES') . Session::get('user_id') . '/';
$profile_folder = $folder_name . 'profile/';

// create a folder for the user's images
if (!(is_dir($folder_name) || is_writable($folder_name))) {
    umask(0); <------
    mkdir($folder_name, 0777);
}           

if (!(is_dir($profile_folder) || is_writable($profile_folder))) {
    umask(0); <------
    mkdir($profile_folder, 0777, true);
}

This did not solve the problem. Running (umask();) returns 18.
Running chmod() after mkdir() did not help either.

My php user is www-data.
My apache user is 'user'.
There are no error messages.

I do not know where else to look for solutions. I would be very thankful for any help.

EDIT:

Putting it all in one statement does not solve the problem either.

    $folder_name = Config::get('PATH_IMAGES') . Session::get('user_id') . '/profile/';

    // create a folder for the user's images            
   if (!(is_dir($folder_name) || is_writable($folder_name))) {
        mkdir($folder_name, 0777, true);            
   }

@Chalotte Dunosis I tried using chmod() after mkdir() as well, but that did not change anything... — Schwesi, Aug 09 '15 at 19:55
which are the permissions for the folder that contains folder_name? — Juan Girini, Aug 09 '15 at 19:56
@Juancho Ramone Fully unrestricted (drwxrwxrwx 3 user user 4096 Aug 9 21.52 images) — Schwesi, Aug 09 '15 at 19:58
Can't you create both folders in the same instruction by setting the recursive parameter to TRUE instead? — Juan Girini, Aug 09 '15 at 20:04
the second part is necessary, because I reuse this function in my project. A couple of times, therefore now it is 'profile' (for profile images) somewhere else it will be 'post' (for images uploaded in posts) etc. — Schwesi, Aug 09 '15 at 20:07
When you used `chmod()` did it return true? Check for that and if it does, check the folders permissions in FTP or SSH. — Charlotte Dunois, Aug 09 '15 at 20:09
It looks like mkdir() sometimes does not like the trailing slashes https://bugs.php.net/bug.php?id=42739 I'd try without them — Juan Girini, Aug 09 '15 at 20:10
@Juancho Ramone that sounds very promising, but how could I create a path without the slashes? (Sorry, I am really new to all this) — Schwesi, Aug 09 '15 at 20:15
you only need to remove the last slash, change `$folder_name = Config::get('PATH_IMAGES') . Session::get('user_id') . '/'; $profile_folder = $folder_name . 'profile/';` to `$folder_name = Config::get('PATH_IMAGES') . Session::get('user_id'); $profile_folder = $folder_name . '/' . 'profile';` — Juan Girini, Aug 09 '15 at 20:19
@JuanchoRamone That did not work, unfortunately. Same result. First folder, without unrestricted permissions. — Schwesi, Aug 09 '15 at 20:22
@CharlotteDunois using ssh to check the permissions gives me the same result. I am not quite sure how to check if chmod returns true, but I do not get any error message running chmod. — Schwesi, Aug 09 '15 at 20:23
@kringeltorte Add after the first if clausel `die(var_dump(chmod($folder_name, 0777))); `, it will stop script execution and output the return of the chmod(). — Charlotte Dunois, Aug 09 '15 at 20:27
@CharlotteDunois Thank you for the details! It returns bool(true). Folder permission is still restricted. — Schwesi, Aug 09 '15 at 20:30
Can you try changing the PHP's user to the same user as Apache and then try again? — Charlotte Dunois, Aug 09 '15 at 20:32
@CharlotteDunois Apache completely stopped working after changing the php user (Invalid Mutex directory in argument file:${APACHE_LOCK_DIR}). Therefore, I guess I will have to reprovisioion and reinstall vagrant. I will get back to you as soon as I managed to achieve this. Thank you so much for all your help up until here!! — Schwesi, Aug 09 '15 at 20:52

use chmod($folder,0755) (or 0777) after mkdir()

Thank you! I tried that back then. I actually never found a solution for it, I think it was something very weird, which was not directly related to the code. – Schwesi Nov 25 '16 at 19:57
