Code

public static final function parseConnectionInfo(array $info) {

  // If there is no "driver" property, then we assume it's an array of
  // possible connections for this target. Pick one at random. That allows
  // us to have, for example, multiple replica servers.
  if (empty($info['driver'])) {
    $info = $info[mt_rand(0, count($info) - 1)];
  }

  // Parse the prefix information.
  // @todo in Drupal 10, fail hard if $info['prefix'] is an array.
  // @see https://www.drupal.org/project/drupal/issues/3124382
  if (!isset($info['prefix'])) {

    // Default to an empty prefix.

    unset($info['prefix']['default']);

    // If there are keys left besides the 'default' one, we are in a
    // multi-prefix scenario (for per-table prefixing, or migrations).
    // In that case, we put the non-default keys in a 'extra_prefix' key
    // to avoid mixing up with the normal 'prefix', which is a string since
    // Drupal 9.1.0.
    if (count($info['prefix'])) {
      $info['extra_prefix'] = $info['prefix'];
    }
