Непрограммисту интересно, не является ли это вредоносным кодом в пост-шаблоне Wordpress

Это находится в моем файле пост-шаблона в папке include (Wordpress), и мне интересно, есть ли это злонамеренный. Обнаружено с помощью подключаемого модуля файлового монитора, который показал изменение файла, но я не знал, может ли это быть результатом какого-то не вредоносного процесса. Извините, если я не ввожу как следует. Цените вашу помощь. Пожалуйста, примите, что я ничего не знаю, потому что не знаю.
