This function behaves exactly like <A
HREF="function.ifx-connect.html"
><B
CLASS="function"
>ifx_connect()</B
></A
>
when PHP is not running as an Apache module.
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
><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.ifx-close.html"
><B
CLASS="function"
>ifx_close()</B
></A
> will not
close links established by <B
CLASS="function"
>ifx_pconnect()</B
>).
</P
><P
>
This type of links is therefore called 'persistent'.
