Establishes a new connection to an Oracle server and logs on.

Unlike <function>oci_connect</function> and
<function>oci_pconnect</function>, <function>oci_new_connect</function>
does not cache connections and will always return a brand-new freshly
opened connection handle. This is useful if your application needs
transactional isolation between two sets of queries.
