What are the best practices for implementing sorting functionality in a PHP-based dynamic table?

When implementing sorting functionality in a PHP-based dynamic table, it is important to handle the sorting logic on the server-side to ensure efficient processing and data manipulation. One common approach is to pass the sorting criteria (such as column name and order) through query parameters in the URL, then use these parameters to modify the SQL query fetching the data. By dynamically adjusting the SQL query based on the sorting criteria, you can easily sort the table data without reloading the entire page. 

// Retrieve the sorting criteria from query parameters
$sort_column = isset($_GET['sort_column']) ? $_GET['sort_column'] : 'default_column';
$sort_order = isset($_GET['sort_order']) ? $_GET['sort_order'] : 'ASC';

// Modify the SQL query based on sorting criteria
$sql = "SELECT * FROM table_name ORDER BY $sort_column $sort_order";

// Execute the SQL query and fetch the data
$result = mysqli_query($conn, $sql);

// Display the table data
echo '<table>';
while ($row = mysqli_fetch_assoc($result)) {
    echo '<tr>';
    echo '<td>' . $row['column1'] . '</td>';
    echo '<td>' . $row['column2'] . '</td>';
    // Add more columns as needed
    echo '</tr>';
}
echo '</table>';
