Мое отображение HTML-сетки элементов начальной загрузки 5 не отображается в моем php-файле [закрыто]

Я пытаюсь отобразить макет сетки HTML в файле php с именем Gardenshop.php. Внутри контейнера сетки должны находиться элементы сетки в виде карточек Bootstrap 5, которые создаются динамически. Контейнер сетки (a) имеет класс .items-wrapper.
На стороне MySQL я использую Sequelize с таблицей Treeseeds.
Я использую PDO (PHP) Data Object) в файле с именем shopconnect.php, чтобы установить соединение с моей базой данных и запросить данные обратно с помощью запросов выбора MySQL, как обычно.

Есть файл Gardenshop.css, который я включил с помощью тега в Gardenshop.php.
Я попробовал свой код, приведенный выше, через XAMMP (рендеринг php Gardenshop.php с использованием Apache)
Я получаю следующий результат на изображении ниже. Я хотел бы знать, как заставить карты начальной загрузки 5 динамически отображаться в сетке. Динамически в том смысле, что мне не нужно жестко кодировать элементы сетки; если я хочу добавить больше данных о семенах деревьев в свою базу данных, я могу это сделать, а затем, когда веб-страница Gardenshop.php будет загружена (через локальный хост в моем браузере), она автоматически отобразит правильное количество элементов сетки (карточек).

Есть файл Gardenshop.css, который я включил с помощью тега в Gardenshop.php.
Я попробовал свой код, приведенный выше, через XAMMP (рендеринг php Gardenshop.php с использованием Apache)
Я получаю следующий результат на изображении ниже. Я хотел бы знать, как заставить карты начальной загрузки 5 динамически отображаться в сетке. Динамически в том смысле, что мне не нужно жестко кодировать элементы сетки; если я хочу добавить больше данных о семенах деревьев в свою базу данных, я могу это сделать, а затем, когда веб-страница Gardenshop.php будет загружена (через локальный хост в моем браузере), она автоматически отобразит правильное количество элементов сетки (карточек).
