  $newAr[] = "<a href='" . base_url() . "note/search/" . $row['id'] . "' class='tag_link'>" . $row['name'] . "</a>";

echo implode(', ', $newAr) . '.';

Функция next(); перемещает внутренний указатель массива на одну позицию вперёд перед тем, как вернуть значение. Цикл foreach тоже перемещает указатель на каждой итерации.
Я думаю, нужно одно из двух устранить. Либо перепишите цикл на while, либо уберите next.

Поддержу @Adamos.
Тоже самое будет, если написать


echo implode(',', $posttags) . '.';
