PHP PDO exception: could not find driver
提问by Absolute?ER?
Does the MySQL-server and PHP5-MySQLi version have to match in order for a connection to be possible? I'm currently receiving the error below: I am running BSD. "Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'..."
MySQL-server 和 PHP5-MySQLi 版本是否必须匹配才能进行连接？我目前收到以下错误：我正在运行 BSD。“致命错误：未捕获异常‘PDOException’，消息‘找不到驱动程序’……”
Here is the the connection info:
这是连接信息：
$info = "mysql:dbname=myDB;host=localhost";
$user = "dbUser";
$pw = "somePW";
return(new PDO($info, $user, $pw));
Here is my MySQL information:
这是我的 MySQL 信息：
mysql-server-5.5.24
mysql-server-5.5.24
php5-mysqli-5.4.3

PDO uses database specific driversto connect to database systems. It looks like you are missing the pdo_mysql driver that is required to connect to a MySQL database. There is some details on installing the driver on the pdo_mysql manualpage, or there may be a BSD package that you can use (I am afraid I'm not familiar enough with BSD to offer specific advice).
PDO 使用特定于数据库的驱动程序连接到数据库系统。看起来您缺少连接到 MySQL 数据库所需的 pdo_mysql 驱动程序。pdo_mysql 手册页上有关于安装驱动程序的一些详细信息，或者可能有您可以使用的 BSD 包（恐怕我对 BSD 不够熟悉，无法提供具体建议）。

I had this same issue on my CentOS install. I had tried to install imagick and hosed my install. When I removed all of my php files and reinstalled something wasn't working right.
我在安装 CentOS 时遇到了同样的问题。我曾尝试安装 imagick 并冲洗了我的安装。当我删除所有 php 文件并重新安装时，某些东西无法正常工作。
I ran:
我跑了：
yum install php-pdo
yum install php-pdo_mysql
After doing those two lines I ran
做了这两行后，我跑了
service httpd restart
and everything came back up and running.
一切都恢复了运行。
