Best way to document Array options in PHPDoc?

Question

I\'m struggling to write readable and easy to understand documentation that describes the multi-tree structure for Array options that are passed to a function.

Here

Answer 1

A bit too late to the party but this is how I do it instead:

/**
 * Class constructor.
 *
 * @param array $params Array containing the necessary params.
 *    $params = [
 *      'hostname'     => (string) DB hostname. Required.
 *      'databaseName' => (string) DB name. Required.
 *      'username'     => (string) DB username. Required.
 *      'password'     => (string) DB password. Required.
 *      'port'         => (int) DB port. Default: 1433.
 *      'sublevel'     => [
 *          'key' => (\stdClass) Value description.
 *      ]
 *    ]
 */
 public function __construct(array $params){}

Think it's quite clean and easy to understand what $params should be.
