Read the manual:

http://www.php.net/manual/en/configuration.php#ini.open-basedir

Limit the files that can be opened by PHP to the specified directory-tree.

When a script tries to open a file with, for example, fopen or gzopen, the
location of the file is checked. When the file is outside the specified
directory-tree, PHP will refuse to open it. All symbolic links are resolved,
so it's not possible to avoid this restriction with a symlink.

The special value . indicates that the directory in which the script is
stored will be used as base-directory.

Under Windows, separate the directories with a semicolon. On all other
systems, separate the directories with a colon. As an Apache module,
open_basedir paths from parent directories are now automatically inherited.

The restriction specified with open_basedir is actually a prefix, not a
directory name. This means that "open_basedir = /dir/incl" also allows
access to "/dir/include" and "/dir/incls" if they exist. When you want to
restrict access to only the specified directory, end with a slash. For
example: "open_basedir = /dir/incl/"
