PHP mkdir 0777 fail chmod 0777 works

Question

using PHP 5.2.14, this is what happens

[user@VE213 public_html]$ php -r "mkdir('directory', 0777);"
[user@VE213 public_html]$ ls -lt
drwxrwxr-x  2 rankranger rankranger 4096 Dec  8 17:28 directory

[user@VE213 public_html]$ php -r "chmod('directory', 0777);"
[user@VE213 public_html]$ ls -lt
drwxrwxrwx  2 rankranger rankranger 4096 Dec  8 17:28 directory

Did not find any related bugs in the php bug list, any idea?

What's your umask? (Does mkdir use umask?) – Rup Dec 08 '10 at 17:32 — Rup, Dec 08 '10 at 17:32

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

Read this, http://php.net/manual/en/function.mkdir.php

Additional, Check the top directory that you make new directory.

Example)

pwd /data/log

$dir="/data/log/query";
$old = umask(0); 
mkdir($dir,0777); 
umask($old);

/data/log must 0777.

This is not a bug. See http://php.net/umask - you probably have an umask of 0002. The permission of what you create is yourmode & ~umask, so it takes the write-bit for everyone away from 0777.

Working as documented. mkdir respects umask, chmod doesn't.

It might work at it is supposed to, but the whole principle of umask is usually not what you would expect. – Bjarke Freund-Hansen Dec 08 '10 at 19:11
