What potential issue arises when trying to use an object of type mysqli_result as an array?

When trying to use an object of type mysqli_result as an array, you may encounter an error because mysqli_result objects do not directly support array operations like accessing elements by index. To solve this issue, you can fetch the rows from the mysqli_result object and store them in a regular PHP array. This way, you can access the data using array syntax.

// Assuming $result is a mysqli_result object
$rows = array();
while ($row = $result->fetch_assoc()) {
    $rows[] = $row;
}

// Now $rows is a regular PHP array containing the fetched rows
// You can access the data using array syntax, for example:
echo $rows[0]['column_name'];
