     (persistent) link that's already open with the same host,
     username and password.  If one is found, an identifier for it
     will be returned instead of opening a new connection.
    </P

>&#13;     Second, the connection to the SQL server will not be closed when
     the execution of the script ends.  Instead, the link will remain
     open for future use (<A

><B

     close links established by <B

      Note, that these kind of links only work if you are using
      a module version of PHP. See the
      <A

>Persistent
      Database Connections</A
> section for more information.
