     * Retrieves the value of an array element or object property with the given key or property name.
     * If the key does not exist in the array or object, the default value will be returned instead.
     *
     * The key may be specified in a dot format to retrieve the value of a sub-array or the property
     * of an embedded object. In particular, if the key is `x.y.z`, then the returned value would
     * be `$array['x']['y']['z']` or `$array->x->y->z` (if `$array` is an object). If `$array['x']`
     * or `$array->x` is neither an array nor an object, the default value will be returned.
     * Note that if the array already has an element `x.y.z`, then its value will be returned
     * instead of going through the sub-arrays. So it is better to be done specifying an array of key names
     * like `['x', 'y', 'z']`.

     * $fullName = \yii\helpers\ArrayHelper::getValue($user, function ($user, $defaultValue) {
     *     return $user->firstName . ' ' . $user->lastName;
     * });
     * // using dot format to retrieve the property of embedded object
     * $street = \yii\helpers\ArrayHelper::getValue($users, 'address.street');
     * // using an array of keys to retrieve the value
     * $value = \yii\helpers\ArrayHelper::getValue($versions, ['1.0', 'date']);
     * ```
     *
     * @param array|object $array array or object to extract value from
     * @param string|\Closure|array $key key name of the array element, an array of keys or property name of the object,
     * or an anonymous function returning the value. The anonymous function signature should be:
     * `function($array, $defaultValue)`.
     * The possibility to pass an array of keys is available since version 2.0.4.
     * @param mixed $default the default value to be returned if the specified array key does not exist. Not used when
     * getting value from an object.
     * @return mixed the value of the element if found, default value otherwise
