In terms of performance, is it more efficient to pass values to PHP for processing or to perform calculations directly in the database?

When deciding whether to pass values to PHP for processing or to perform calculations directly in the database, it is generally more efficient to let the database handle calculations whenever possible. Databases are optimized for processing large amounts of data quickly and efficiently, so performing calculations within the database can often be faster than retrieving data and processing it in PHP. However, there may be cases where complex calculations or logic are better suited for PHP processing. 

// Example of performing calculations directly in the database
$query = "SELECT SUM(column_name) AS total FROM table_name";
$result = mysqli_query($connection, $query);
$row = mysqli_fetch_assoc($result);
$total = $row['total'];
echo "Total: " . $total;
