What are best practices for sorting data in PHP queries based on calculated values?

When sorting data in PHP queries based on calculated values, it is best to perform the calculation within the SQL query itself rather than in PHP code. This ensures that the sorting is done efficiently at the database level. You can use SQL functions to calculate values and then sort the data based on those calculated values. 

// Example PHP code snippet for sorting data based on calculated values in SQL query

// Connect to database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare SQL query with calculation and sorting
$stmt = $pdo->prepare("SELECT *, (column1 + column2) AS calculated_value FROM mytable ORDER BY calculated_value DESC");

// Execute query
$stmt->execute();

// Fetch and display results
while ($row = $stmt->fetch()) {
    echo $row['column1'] . ' ' . $row['column2'] . ' ' . $row['calculated_value'] . '<br>';
}
