<function>sybase_connect</function> establishes a connection to a
Sybase server.
</para>

In case a second call is made to
<function>sybase_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.
</para>
<para>
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>sybase_close</function>.

This allow you to make separate connections in the same script to the
same database. This may come handy when you have started a transaction
in your current connection, and you need to be able to do a separate
query which cannot be performed inside this transaction.
