假设实体管理器为$this->em

从Symfony2获取教义数据库名称：

$this->em->getConnection()->getDatabase();

从Symfony2取得Doctrine主机名称（服务器名称）：

$this->em->getConnection()->getHost();

您可以从连接访问许多其他参数，如username、port和password。有关详细信息，请参阅connection class

例如：

foreach(Doctrine_Manager::getInstance()->getConnections() as $connection){
  $conn = $connection->getOptions();
  preg_match('/host=(.*);/', $conn['dsn'], $host);
  var_dump($host);
}

DSN中特定连接的dbname：
databases.yml

all:
  conexion1:
    class: sfDoctrineDatabase
    param:
      dsn: 'mysql:host=localhost;dbname=basegestion1'
      username: miusuario
      password: ********
  conexion2:
    class: sfDoctrineDatabase
    param:
      dsn: 'mysql:host=localhost;dbname=baseestadisticas1'
      username: miusuario
      password: ********

在“操作：

$mConexion1Options = Doctrine_Manager::getInstance()->getConnection('conexion1')->getOptions();
preg_match('/dbname=(.*)/', $mConexion1Options['dsn'], $mDbConexion1);

然后，dbname为：

echo $mDbConexion1[1]; //basegestion1

使用此代码：

$myConnection           = Doctrine_Manager::getInstance()->getConnection('doctrine')->getOptions();
$dsnInfo                = $this->parseDsn($myConnection['dsn']);
$settings               = array();
$settings['dbUser']     = (string) $myConnection["username"];
$settings['dbPassword'] = (string) $myConnection["password"];
$settings['dbHost']     = (string) $dsnInfo["host"];
$settings['dbName']     = (string) $dsnInfo['dbname'];

private function parseDsn ($dsn)
{
  $dsnArray            = array();
  $dsnArray['phptype'] = substr($dsn, 0, strpos($dsn, ':'));
  preg_match('/dbname  = (\w+)/', $dsn, $dbname);
  $dsnArray['dbname']  = $dbname[1];
  preg_match('/host    = (\w+)/', $dsn, $host);
  $dsnArray['host']    = $host[1];

  return $dsnArray;
}

试试这个

$conn = Doctrine_Manager::getInstance()->getConnection('doctrine')->getOptions();

$dns_array = split(';', $conn['dsn']);
preg_match('/host=(.*);/', $dns_array, $dbhost);
preg_match('/dbname=(.*)/', $dns_array, $dbname);

$dbname = $dbname;
$dbhost = $dbhost;
$dbuser = $conn['username'];
$dbpass = $conn['password'];

已更新

如Function split() is deprecated那么这里推荐的方式是。

$dns_array = explode(';', $conn['dsn']);
preg_match('/host=(.*)/', $dns_array[0], $dbhost);
preg_match('/dbname=(.*)/', $dns_array[2], $dbname);

$dbhost = $dbhost[1];
$dbname = $dbname[1];
$dbuser = $conn['username'];
$dbpass = $conn['password'];

现代（截至2022年10月）Doctrine DBAL 3.4.5和持久性2.5.4的答案

在Doctrine的现代迭代中，我只能通过注入ManagerRegistry来获得Doctrine连接的名称（如doctrine.yaml文件中所配置的）：

use Doctrine\DBAL\Connection;
use Doctrine\Persistence\ManagerRegistry;
use Doctrine\Persistence\ObjectManager;

// ...

    private function getConnectionName(ManagerRegistry $managerRegistry, Connection $targetConnection): string
    {
        foreach ($managerRegistry->getConnections() as $connectionName => $connection) {
            if ($targetConnection === $connection) {
                return $connectionName;
            }
        }

        return '<unrecognized connection>';
    }

// ...
