Are there any specific PHP functions or methods that are recommended for handling summed data from a database query?

When handling summed data from a database query in PHP, the `SUM()` function in SQL can be used to calculate the total sum of a column. Once the sum is retrieved from the query result, it can be accessed and displayed using PHP. Additionally, the `mysqli_fetch_assoc()` function can be used to fetch the summed data from the query result set.

// Assuming $conn is the mysqli connection object

$query = "SELECT SUM(column_name) AS total_sum FROM table_name";
$result = mysqli_query($conn, $query);

if ($result) {
    $row = mysqli_fetch_assoc($result);
    $totalSum = $row['total_sum'];
    
    echo "Total Sum: " . $totalSum;
} else {
    echo "Error: " . mysqli_error($conn);
}
