基于 drupal 的网站突然出现 pdo_mysql 错误？
我的基于 drupal 的网站直到昨天都工作正常，但今天突然从哪里出现错误
Fatal error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY' in /.../includes/database/mysql/database.inc on line 43
，从昨天开始我什至没有更改或更新任何内容，它突然从任何地方出现，在此之前它工作正常
在 database.inc 的第 43 行这是我写的，
PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => TRUE,
我用谷歌搜索并得到一些想法，这是某种 PDO_MYSQL 错误，我不太清楚为什么这个错误突然出现
任何人都可以帮助我

My drupal based website was working fine till yesterday but suddenly from no where today an error appeared
Fatal error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY' in /.../includes/database/mysql/database.inc on line 43
I didn't even changed or updated anything since yesterday, it suddenly appears from no where, before that it was working fine
On line 43 of database.inc this was written
PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => TRUE,
I googled and got some idea that this is some sort of PDO_MYSQL error, i have not much idea why this error suddenly arrived
Can anyone please help me out

根据许多不同的来源，您的 PHP 安装中一定缺少 pdo_mysql 扩展。将其添加到 php.ini 中或要求您的托管提供商为您执行此操作。

他们都说同样的事情...安装 pdo_mysql 扩展。听起来您的托管提供商已禁用它！
According to a lot of different sources the pdo_mysql extension must be missing from your PHP installation. Either add it in php.ini or ask your hosting provider to do it for you.

They all say the same thing...install the pdo_mysql extension. Sounds like your hosting provider has disabled it!
这也可能是由于权限问题造成的。有时，考虑到使用 SuPHP 或其他配置，其中 apache（或其他服务器）用户无法运行文件，您会收到此类错误，并且 PDO_MYSQL: 将已安装并可运行。
如果您具有该框的 root 访问权限，请尝试执行 a
或递归 chown 目录到适当的 apache 用户（通常是 apache 或 www-data）或文件所在主目录的用户（大多数共享服务器中的情况）。
This can also be due to a permissions issue. Sometimes, given the use of SuPHP or other configurations in which the apache (or other server) user can't run a file, you'll get this sort of error and PDO_MYSQL: will already be installed and operational.
If you have root access to the box, try doing a
or recursively chown the directory to the appropriate apache user (usually apache or www-data) or the user who's home directory your files are resting in (the case in most shared servers).
我有完全相同的问题。我的网站突然瘫痪了。
我开始考虑按照上面的建议从 cPanel PHP PEAR 安装 php 扩展 php_pdo_mysql.dll，但这失败了。
我开始与我的主机 (Justhost) 进行实时聊天，结果发现他们已经升级了 php 版本。他们在 2 分钟内就把它修好了。
I had exactly the same problem. My site suddenly went down.
I started looking at installing php extension php_pdo_mysql.dll from cPanel PHP PEAR as suggested above, but this failed.
I started a live chat with my host (Justhost) and it tuned out they had upgraded their php version. They fixed it in 2 minues.
