Permission denied to make directory

[NotionCommotion]

I am sure it is a silly mistake, but don't see it.  Can anyone tell me why I cannot create a directory?  Thanks

echo('filepath1: '.$filepath1.'<br>');
echo('filepath2: '.$filepath2.'<br>');
echo('fileowner: '.posix_getpwuid(fileowner($filepath1))['name'].'<br>');
echo('fileperms: '.substr(sprintf('%o', fileperms($filepath1)), -4).'<br>');
echo('current_user: '.get_current_user().'<br>');
echo('filepath1 exists: '.(file_exists($filepath1)?'Yes':'No').'<br>');
echo('filepath1 is a directory: '.(is_dir($filepath1)?'Yes':'No').'<br>');
echo('filepath2 exists: '.(file_exists($filepath2)?'Yes':'No').'<br>');
if(!file_exists($filepath2)){mkdir($filepath2, 0755);}

filepath1: /var/www/main/user_resources/documents/30
filepath2: /var/www/main/user_resources/documents/30/01
fileowner: NotionCommotion
fileperms: 0755
current_user: NotionCommotion
filepath1 exists: Yes
filepath1 is a directory: Yes
filepath2 exists: No

An error occurred in script '/var/www/main/
application/classes/application.php' on line 197: mkdir(): Permission denied (error no: 2). [12.34.56.789]

The answer is right in the error message: Permission denied

 

You need to set the correct permissions on the directory you are trying to make directory's in for the user trying to make the directory.

Yes, I recognize that permission is denied.  Why?  As I showed on the original post, the parent directory is 0755 and is owned by the PHP user.

[benanamen]

From the manual - mkdir

http://php.net/manual/en/function.mkdir.php

 

 

The mode is 0777 by default, which means the widest possible access. For more information on modes, read the details on the chmod() page.

 

Most likely Php is running as user nobody, not who you think it is.

get_current_user() is not returning the user PHP is running as. Its returning the owner of the script, this is not the user PHP is running as.

 

 

To see who PHP is running as you maybe able to use

echo `whoami`; // yes those are backticks not quotes

@NotionCommotion: Your code checks the permissions of the script owner, but you need to know the UID of the process:

var_dump( posix_getuid() );

That most definitely isn't “NotionCommotion”, rather something like “www-data”.

 

If you want PHP to create directories, you need to make www-data (or whatever the user is called) the owner of the parent directory.

Well, I feel silly.  PHP is being ran as apache.  Probably better to use something like www-data so it is simpler to change websevers if desired.

 

Still odd that I earlier wasn't able to create the directory.  I changed permissions to 0775, and apache belonged to the NotionCommotion group.  Oh well, all is good now, and probably best not to use groups like I did for this.
