-	* Method for chmodding directories and files for internal use.
-	*
-	* This function determines owner and group whom the file belongs to and user and group of PHP and then set safest possible file permissions.
-	* The function determines owner and group from common.php file and sets the same to the provided file.
-	* The function uses bit fields to build the permissions.
-	* The function sets the appropiate execute bit on directories.
-	*
-	* Supported constants representing bit fields are:
-	*
-	* phpbb::CHMOD_ALL - all permissions (7)
-	* phpbb::CHMOD_READ - read permission (4)
-	* phpbb::CHMOD_WRITE - write permission (2)
-	* phpbb::CHMOD_EXECUTE - execute permission (1)
-	*
-	* NOTE: The function uses POSIX extension and fileowner()/filegroup() functions. If any of them is disabled, this function tries to build proper permissions, by calling is_readable() and is_writable() functions.
-	*
-	* @param string	$filename	The file/directory to be chmodded
-	* @param int	$perms		Permissions to set

-	* @return bool	true on success, otherwise false
