英文:

Error comes after updating PHP version in IIS PHP manager

问题 {#heading}

网站在我将PHP版本从v7.4.24更改为v7.4.33后，在IIS PHP管理器中不响应。

错误如下：

PHP致命错误：在E:\inetpub\wwwroot\intranet\includes\database\mysql\database.inc的第56行中未定义的类常量'MYSQL_ATTR_USE_BUFFERED_QUERY'。

#1 在E:\inetpub\wwwroot\intranet\includes\database\mysql\database.inc的第56行中。

我尝试在PHP.ini文件中添加了PDO extension_dir="path"，因为之前未分配目录路径。但结果仍然相同。 英文:

The website is not responding after I change the PHP version from v7.4.24 to v7.4.33 in IIS PHP manager.

The error is as follows:

I tried adding PDO extension_dir="path" in PHP.ini file as there was no path assigned to the directory earlier. But the results were same.

1. 检查你的php.ini配置文件。
2. 寻找这些行并确保它们没有被注释掉：extension=pdo_mysql。
3. 另一个方法是更新Drupal。

英文:

1. check your php.ini configuration file.
2. Look for lines and make sure they are not commented extension=pdo_mysql
