Question

你好尝试连接到数据库，我不能这样做，我用laragon运行程序并显示此错误。数据库连接是使用带有mysql的adodb。感谢帮助。

PHP版本是什么？由于“已弃用”，我在这里（可能）假设7.x消息和最后的致命消息错误。

这是两件事......

已弃用：

PHP已更改使用__construct() （两个前导下划线）作为构造函数，而不是与类本身相同的名称。有关详细信息，请参阅PHP 4 style constructors部分（页面上的第一部分）。

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：

使用PHP 7.x，基于mysql_ *的函数是除去。请参阅this API info。
