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


$old = umask(0);
mkdir($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.
