int mssql_close(int link_identifier);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().
