sybase_close — Closes a Sybase connection
sybase_close() closes the link to a Sybase
database that's associated with the specified link
Note that this isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
sybase_close() will not close persistent links generated by sybase_pconnect().
If the link identifier isn't specified, the last opened link is assumed.
TRUE in caso di successo,
FALSE in caso di fallimento.
