In case a second call is made to <function>ibase_connect</function> with
the same arguments, no new link will be established, but instead, the link
identifier of the already opened link will be returned. The link to the
server will be closed as soon as the execution of the script ends, unless
it's closed earlier by explicitly calling <function>ibase_close</function>.
