Quick question about open_basedir

Question

Hello,

On my server, I have following setting:

open_basedir    

    /home/
    :/usr/lib/php
    :/usr/local/lib/php
    :/tmp/
    :/usr/local/
    :/usr/bin

Now, I am little bit confused about ending / in the / home / setting, does that mean that all subfolders inside home have same rights? or does it mean that only home files can be accessed?

So, basically what is the main difference between:

/home/

and

/home

With example if possible

Thank you in advance.
