php 中与 adodb 的连接出错

Question

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

Answer 1

什么 PHP 版本？由于 'deprecated' 消息和最后一个 'fatal' 错误，我在这里（可能）假设 7.x。

这是一个两部分的问题...

已弃用：

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 class 本身同名。有关详细信息，请参阅 PHP 4 style constructors 部分（页面的第一部分）。

例如：在 ADOConnection has a deprecated constructor... 的文件中，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。
致命错误：

和PHP 7.x，基于mysql_*的函数是删除。见 this API info.
