The expression $this->servicesArray of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using empty($expr) instead to make it clear that you intend to check for an array without elements.

            if (empty($providerArray)) {
                throw new MissingConfigException("There is no services entry for $providerName");
