Since the tables are in the same database, it's not necessary to keep closing and re-opening the database. 由于这些表位于同一数据库中，因此不必保持关闭状态并重新打开数据库。 Use mysql_connect the first time, and then subsequent calls to eg mysql_query will reutilize that same connection, if you don't provide a new one. 第一次使用mysql_connect ，然后，如果不提供新的连接，则对mysql_query的后续调用将重新利用该连接。
