提问by Ricardo Raz
I just try symfony 3 and I am on insert data into database using Doctrine ORM. When I try to run my query
我只是尝试了 symfony 3，我正在使用 Doctrine ORM 将数据插入数据库。当我尝试运行查询时
$customer = new Customer();
$customer->setAddress('Some Address');
$customer->setName('Customer 1');
$order->setQuantity('100');
$order->setDate(date('Y-m-d'));
$order->setCustomer($customer);
$em = $this->getDoctrine()->getManager();
$em->persist($customer);
$em->persist($order);
$em->flush();
but it returns an exception :
但它返回一个异常：
Uncaught PHP Exception Doctrine\DBAL\Exception\DriverException: "An exception occurred in driver: could not find driver" at /home/hei/Sites/practice/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/AbstractMySQLDriver.php line 121
Parameters.yml:
参数.yml：
parameters:
database_host: 127.0.0.1
database_port: null
database_name: practice
database_user: root
database_password: null
Config.yml
配置文件
doctrine:
dbal:
driver: pdo_mysql
host: '%database_host%'
port: '%database_port%'
dbname: '%database_name%'
user: '%database_user%'
password: '%database_password%'
I also check if the extension is enabled and loaded via php -m and phpinfo(). It says that PDO & PDO_Mysql is enabled.
我还检查扩展是否通过 php -m 和 phpinfo() 启用和加载。它说 PDO & PDO_Mysql 已启用。
Then add these two lines in php.ini:
然后在php.ini中加入这两行：
extension=pdo.so
extension=pdo_mysql.so
but I still got the same PDO Exception.
但我仍然得到相同的 PDO 异常。

I believe php-mysql package missing in your system. Install the package using the command
我相信您的系统中缺少 php-mysql 包。使用命令安装包
sudo apt-get install php-mysql
I hope this will fix your issue.
我希望这会解决您的问题。
I think you need to restart Apache also in order to fix the issue. After installing php-mysql use the following command to restart Apache
我认为您还需要重新启动 Apache 才能解决此问题。安装 php-mysql 后使用以下命令重启 Apache
sudo service apache2 restart.

First of all you have to change MySQL port number from nullto 3306. That's it.
I think you don't have MySQL password that's why you didn't write anything.
首先，您必须将 MySQL 端口号从 更改null为3306. 就是这样。我认为您没有 MySQL 密码，这就是您没有写任何内容的原因。
Have a good day.

For me I added these 2 lines in /etc/php/5.6/cli/php.inias they were already present in
对我来说，我添加了这两行，/etc/php/5.6/cli/php.ini因为它们已经存在于
/usr/lib/php/5.6/php.ini-development
/usr/lib/php/5.6/php.ini-development
extension=pdo.so
extension=pdo_mysql.so
Then did:
然后做了：
sudo service apache2 restart
I could then flush entity to database.

Hope this works for anyone else in future.

In WAMPServer and possibly other configurations, there may be a separate php.inifor your command line PHP. Ensure that you enabling your modules in the right .ini (ideally both ini's)
在 WAMPServer 和可能的其他配置中，可能有单独php.ini的命令行 PHP。确保在正确的 .ini 中启用模块（最好是两个 ini）
