PHP mySql fetch all items from table

I'm really new to PHP and mySql, but I'm trying to figure out how to fetch all items from a table. In my item handler class I'm doing

static function getAllItems(){

        $items = array();
        $db = new Database();

        $result = $db->query("SELECT * FROM items");

        while($row = $result->fetch_assoc()){
            $items[] = $row;
        }

        return $items;
}

and then on the client side I'm doing this to iterate through the items returned and display them, but keep getting an error

"Fatal error: Call to a member function getTitle() on a non-object"

What am I doing wrong?

<div class="table-responsive">
        <?php
        $allItems = ItemHandler::getAllItems();

        if(empty($allItems)){
            echo '<p class="lead text-center">No listings in this category yet.</p>';
        } else {
            echo '<table class="table">

            <tr>
            <th>Image</th>
            <th>Item Name</th>
            <th>Quantity</th>
            <th>Description</th>
            <th>Seller</th>
            <th>Price</th>
            <th>Purchase</th>
            </tr>';


            foreach($allItems as $item){
                echo "<tr>
                <td>blank</td>
                <td>{$item->getTitle()}</td>
                <td>1</td>
                <td>{$item->getDescription()}</td>
                <td>test seller</td>
                <td>{$item->getPrice()}</td>
                <td><a href='#'><button type='button' class='btn btn-primary'>Buy</button></a></td>
                </tr>";
            }

            echo '</table>';
        }

        ?>

</div>
