PHP mkdir() permissions

Question

I have a Linux server with appache as the web server. In my PHP script I am making directories with 0777 mode. the code is pretty simple as follows:

mkdir($path,0777)

when I run this script and go to my server file manager, the folder is there but the permission assigned to that folder is 0755. I can't figure out why this is happening!! when the folder is created the user column has apache in it but the permission is 0755.

Solution 1

You should try with the umask

$old = umask(0); 
mkdir($path,0777); 
umask($old); 

Solution 2

You can try:

chmod ( string $filename , int $mode )

See if that can fix the permissions issue.

Normally, umask is 022, which means to ignore any group or other write permissions. So if the permissions requested are 0777, then the permissions granted are 0777 - 022 = 0755.

Changing umask is not the safest way to do this. The approach suggested by Kart Funai here stackoverflow.com/a/7878810/3153786 is safer
