Here's my suggestions:

    session.auto_start      Off
    session.use_cookies     On
    session.use_trans_sid   Off
    magic_quotes_runtime    Off   [1]
    magic_quotes_gpc        Off   [2]
    register_globals        Off   [3]
    display_errors          On for debugging, Off for production [4]
    session.cookie_lifetime 0

1.  The setting for magic_quotes_runtime generally doesn't matter;
    PmWiki forces magic_quotes_runtime to 'off' when it runs.

2.  Similarly, the actual setting of magic_quotes_gpc isn't important,
    as PmWiki knows how to accommodate either setting.

3.  Register globals should always be off, if at all possible.

4.  Generally I leave the php.ini setting for this alone, and manually
    set the value of display_errors in local/config.php if I'm
    interested in troubleshooting a problem.

        ini_set('display_errors', 0);    # disable error display
        ini_set('display_errors', 1);    # enable error display

Hope this helps,
