我在本地服务器上安装了打开的购物车,但它在顶部显示一条消息。

已弃用:mysql_connect():mysql 扩展已弃用,将来将被删除:在第 6 行的 D:\new\htdocs\business\system\database\mysql.php 中使用 mysqli 或 PDO 代替

我该如何解决?

此错误是因为您使用的是 PHP 5.5 或更高版本。最好的解决方案是不要像其他人所说的那样抑制错误(因为这会阻止您看到其他问题的错误),而是为 OpenCart 安装 mysqli 扩展/PDO 扩展。这个是免费的,而且效果很好——这是我用的那个

我在 ApacheFriends XAMPP 版本 1.8.3 上使用 opencart-1.5.6.1.zip,我在每个页面上也看到了这个错误消息。

打开 opencart/config.php 和 opencart/admin/config.php。

编辑'mysql'->'mysqli'

例如

//define('DB_DRIVER', 'mysql');
define('DB_DRIVER', 'mysqli');

保存文件,无需重新启动任何东西。错误信息消失了。
