【问题描述】：
我在本地主机上运行时收到错误消息。跟随我得到的味精。我还添加了数据库连接代码。
( ! ) Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in C:\wamp\www\common\conf\database.conf.php on line 51

?>【问题讨论】：
-
mysql PHP 扩展已死 -- 停止使用 mysql PHP 扩展。它是旧的，自 PHP 5.5 起已弃用，并在 PHP 7.0 中完全删除。请改用 mysqli 或 PDO_mysql。并且不要混合它们
-
Mysql_* 函数已弃用。此外，它们是不安全的Deprecated features in PHP 5.5.x。您应该使用 mysqli_ 函数或更好的 PDO 与准备好的语句。
