note 16386 added to function.mkdir

What can I do if I want to use "mkdir()" funkction in my php files but system says - "I haven't Permissions" because I am not webmaster but a simpe user with my /~user/file.php. When I am using MkDir, the web server is trying to create directory with web's default username and graupname (nobody or else) in my directory with permisions only for me. Is there a problem in Apache web server configuration? -- http://www.php.net/manual/en/function.mkdir.php http://master.php.net/manage/user-notes.php?action=edit+16386 http://master.php.net/manage/user-notes.php?action=delete+16386 http://master.php.net/manage/user-notes.php?action=reject+16386
