     First, when connecting, the function would first try to find a
     (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

     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
HREF="function.mysql-close.html"
><B
CLASS="function"
>mysql_close()</B
></A
> will not
     close links established by <B
CLASS="function"
>mysql_pconnect()</B
>).
    </P
><P

     This type of links is therefore called 'persistent'.
