Долго пробую сделать вывод переменной из массива, но не выходит. Я новичок. чуть более месяца как начал разбираться. Извиняюсь заранее, возможно, тут решение банальное, но у меня упорно не выходит.
Опишу проблему. Есть на сайте рейтинг в виде звезд. Нужно что бы в нужном месте можно было вывести результат рейтинга в числовом виде. Код вывода переменной примерно такой <?php echo rating_bar('id1',''); ?>, но этом коде выводится все составные рейтинга. Переменная $count, отвечает за средний рейтинг всех голосов, эту переменную нужно вывести? нужно выводить по id, у каждого id разное значение переменной.
Ниже приведу код из двух файлов, которые отвечают за вывод. Я не пойму к чему в коде обращаться.
