php - php 中与 adodb 连接时出错

Question

您好，尝试连接到数据库，但我无法执行此操作，我使用 laragon 运行程序并显示此错误。数据库连接是adodb和mysql。感谢帮助。

Answer 1

什么 PHP 版本？由于“已弃用”消息和最后一个“致命”错误，我假设此处为 7.x(可能)。

这是一个两部分的问题......

1. 已弃用的:

   PHP 已更改为使用 __construct()(两个前导下划线)作为构造函数，而不是与类本身同名。请参阅PHP 4 style constructors部分(页面的第一部分)了解更多信息。

   例如:在ADOConnection 文件中，有一个已弃用的
构造函数... 构造函数可能如下所示:

   ADOConnection( ... ); // constructors with or without parameters
   

   ...但所有这些都可以替换为:

   __construct( ... );
   

   您可以在本地进行更改以解决已弃用的消息。

2. fatal error :

   在 PHP 7.x 中，基于 mysql_* 的函数是已删除。请参阅this API info .
