### PHP


To authenticate to Cloud SQL for SQL Server, set up Application Default Credentials.
For more information, see

[Set up authentication for a local development environment](https://docs.cloud.google.com/docs/authentication/set-up-adc-local-dev-environment.md.txt).

```php
// Use prepared statements to guard against SQL injection.
$sql = 'INSERT INTO votes (time_cast, candidate) VALUES (GETDATE(), :voteValue)';

try {
    $statement = $conn->prepare($sql);
    $statement->bindParam('voteValue', $value);

    $res = $statement->execute();
} catch (PDOException $e) {
    throw new RuntimeException(
        'Could not insert vote into database. The PDO exception was ' .
        $e->getMessage(),
        $e->getCode(),
