У меня есть этот код,
<?php foreach($information as $info) : ?>
<option selected="no" value="<?php echo $info['grade_id'];?>" id="<?php echo $info['grade_id'];?>">
<?php echo $info['grade_desc'];?>
</option>
<?php endforeach; ?>
В основном, это то, что он делает, несмотря на некоторые опции для меню выбора, однако иногда опции выбора дублируются, есть ли способ, так что я только когда-либо выплюнул 1экземпляр каждого значения?Используя то, что у меня уже есть в цикле?Например, проверка $info['grade_id']
не совпадает с предыдущей, и если она пропускает эту итерацию?
Так выглядит информационный массив:

Вы можете увидеть вВ результате получается 2 [grade_desc] того же класса GCSE D по математике, английскому языку и успешному завершению дипломной работы 1 уровня кирпичной кладки или эквивалентной.Однако в базе данных есть только одна запись, могу ли я удалить любые повторяющиеся данные массива?
