msql_close — Close mSQL connection
msql_close() closes the non-persistent connection to the mSQL server that's associated with the specified link identifier.
Using msql_close() isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution. See also freeing resources.
TRUE in caso di successo,
FALSE in caso di fallimento.
