PHP Created file | SSH Can't delete (permission denied)

Question

Linux SSH I create a file in php using ``` if (!is_dir(DIR_FILE)) mkdir(DIR_FILE, 0777); $filename = DIR_FILE . $id . '.txt'; $handle_cf = fopen($filename, 'a'); fwrite($handle_cf, $data . "
"); fclose($handle_cf); chmod($filename, 0777); chown($filename, "usr111"); // usr111 = username chgrp($filename, "usr111"); // usr111 = group that is also attached to apache ``` The file gets the following permissions. ``` -rwxrwxrwx 1 apache apache 1447 Apr 4 12:48 D.txt -rwxrwxrwx 1 apache apache 1447 Apr 4 12:48 E.txt ``` however when I try to delete the file, under the regular user account (usr111). I get the following error ``` [usr111@host session]$ rm D.txt rm: cannot remove `D.txt': Permission denied ``` NOTE: I can delete the file under root. FIX FOUND! even though I was using the mode setting on mkdir for php. For some reason this wasn't working. I added the following. ``` if (!is_dir($dir)) { mkdir($dir, 0777); chmod($dir, 0777); } ```

Accepted Answer

mkdir is working well but the second argument isn't the permission it's a mode that will be used by the system together with your current umask to calculate the permissions to set. From manual:

The mode is also modified by the current umask, which you can change using umask().

You need to change your script to set the permissions without calling the filesystem twice:

```
$oldUmask = umask(0); // disable umask
mkdir($path, 0777);
umask($oldUmask);  // reset the umask
```
