I am trying to get and display two values from the database, 'cat_name', and 'cat_description' and display those in a table. A far as I can tell the code is fine. I am pretty new to PHP and have little experience with it.

I have tried going through many questions, and tried many possible answers. I cant really tell how many attempts I have tried to fix this issue.

    $query = $con->prepare("SELECT cat_id, cat_name, cat_description FROM categories");

    $result = $query->fetchAll(PDO::FETCH_ASSOC);
        //something went wrong, display the error
        echo 'Error'; 
        if($result == 0)
            echo 'No categories defined yet.';
            echo '<table border ="1">
                    <th>Last Topic</th>


            while($row = mysqli_fetch_array($result)){
            echo '<tr>';
            echo '<td class="leftpart">';
                echo '<h3><a href="category.php?id">' . $row['cat_name'] . '</a></h3>' . $row['cat_description'];
            echo '</td>';
            echo '<td class="rightpart">';
                echo '<a href="topic.php?id=">Topic subject</a> at 10-10';
            echo '</td>';
            echo '</tr>';


I am supposed to expect a table showing two columns one showing Categories (hyperlinked) with a small description of the category taking from the database. And another column for topics within that category but have not been able to get that far as of yet.

Expected outcome:

When I run this code all I seem to achieve is an error.

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, array given
