> creates a new connection to an
     Oracle 8 database and logs on.  The optional third parameter can
     either contain the name of the local Oracle instance or the name
     of the entry in tnsnames.ora to which you want to connect.  If
     the optional third parameter is not specified, PHP uses the
     environment variables ORACLE_SID (Oracle instance) or TWO_TASK
     (tnsnames.ora) to determine which database to connect to.

>&#13;     <B
CLASS="function"

> forces a new connection.  This
     should be used if you need to isolate a set of transactions.  By
     default, connections are shared at the page level if using
     <B
CLASS="function"
>OCILogon()</B
> or at the web server process level
     if using <B
CLASS="function"
>OCIPLogon()</B
>.  If you have multiple
     connections open using <B
CLASS="function"
>OCINLogon()</B
>, all
     commits and rollbacks apply to the specified connection only.
