在 symfony2 中为 Doctrine DBAL 配置设置 driverOptions 的正确方法

Question

I have set driverOptions in the config file as mentioned in the doctrine DBAL documentation.

But this gives an error

1/1 InvalidConfigurationException: Unrecognized options "driverOptions" under "doctrine.dbal.connections.pdoDevCon"

My config file is

dbal:
  default_connection: pdoDevCon
  connections:
    pdoDevCon:
      driver:   %dev_database_driver%    # <
      host:     %dev_database_host%      # |
      port:     %dev_database_port%      # | Defined in
      user:     %dev_database_user%      # |
      password: %dev_database_password%  # <   
      charset:  UTF8
      driverOptions: {3: 2}
      mapping_types:
        enum: string
        set: string

orm:
    auto_generate_proxy_classes: %kernel.debug%
     pdoDevCon:
        connection: pdoDevCon
        mappings:
          AcmeDemoBundle: ~
          AcmeHelloBundle: ~ 

I am using PDO::ATTR_ERRMODE as 3 PDO::ERRMODE_EXCEPTION as 2 , it does not work even if i use the strings.

From http://symfony.com/doc/master/reference/configuration/doctrine.html#doctrine-dbal-configuration

DoctrineBundle supports all parameters that default Doctrine drivers accept, converted to the XML or YAML naming standards that Symfony enforces . See the Doctrine DBAL documentation for more information.

There is no driverOptions in symfony yml configuration file, just options

I'm not using Symfony but I was using Doctrine\\DBAL\\DriverManager::getConnection() .

I had to side step the DriverManager and do this song and dance to specify a connection timeout ( ATTR_TIMEOUT ):

function buildDbConn($config, $timeout) {
    $params = $config->toArray();
    $params['driverOptions'] = [
        PDO::ATTR_TIMEOUT => intval($timeout),
        PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
    ];
    $driver = new Doctrine\DBAL\Driver\PDOMySql\Driver;
    return new Doctrine\DBAL\Connection($params, $driver);
}

I always need a pdo_mysql driver, this could be configurable.

You can set this option from the yml. The thing is that you nezd to use the const value:

The option param will be copied as driver option dont worry

The int is 2

options 2: 10

works for me i. Symfony 3.4 and 4.2
