如何从 Doctrine\DBAL\Connection 获取 php-native handle？

Question

给定代码

$connectionParams = array(
    'dbname' => $this->dbname,
    'user' => $this->dbuser,
    'password' => $this->dbpass,
    'host' => $this->dbhost,
    'driver' => 'mysqli',
);

$conn = \Doctrine\DBAL\DriverManager::getConnection($connectionParams);        
var_dump($conn);

如何从 $conn（Doctrine\DBAL\Connection）获取底层的 mysqli 句柄？

我找到了*一种方法*来访问它，但它显然不是它应该完成的方式，所以我愿意提出建议：

$conn = \Doctrine\DBAL\DriverManager::getConnection($connectionParams);        
foreach((array)$conn->getWrappedConnection() as $mysqli){
    // TODO: find official way of getting the handle.
    // here we are casting it to (array) to access its PRIVATE PROPERTIES
    // it's a fugly hack. 
    break;
}
var_dump($mysqli);

您可以这样获取：

$mysqli = $conn->getWrappedConnection()->getWrappedResourceHandle();
