Returns: TRUE on
success, FALSE on error.
mssql_close() closes the link to
a MS SQL Server database that's associated with the specified
link identifier. If the link identifier isn't specified, the
last opened link is assumed.
Note that this isn't usually necessary, as non-persistent
open links are automatically closed at the end of the
script's execution.
mssql_close() will not close
persistent links generated by
mssql_pconnect().
