Are there any potential pitfalls in storing query results in arrays before displaying them in a table?

Storing query results in arrays before displaying them in a table can potentially lead to increased memory usage and slower performance, especially for large datasets. To mitigate this, consider using server-side pagination to limit the number of records fetched and displayed at a time. This approach can help improve the overall efficiency of your application by reducing the amount of data stored in memory and enhancing user experience. 

// Example of implementing server-side pagination in PHP
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$records_per_page = 10;
$offset = ($page - 1) * $records_per_page;

$query = "SELECT * FROM your_table LIMIT $offset, $records_per_page";
// Execute the query and fetch results

// Display results in a table
echo '<table>';
foreach ($results as $row) {
    echo '<tr>';
    foreach ($row as $value) {
        echo '<td>' . $value . '</td>';
    }
    echo '</tr>';
}
echo '</table>';

// Pagination links
$total_records = // Get total number of records from the database
$total_pages = ceil($total_records / $records_per_page);

for ($i = 1; $i <= $total_pages; $i++) {
    echo '<a href="?page=' . $i . '">' . $i . '</a>';
}
