What are the advantages and disadvantages of performing calculations directly in MySQL queries versus using PHP for easier debugging?

Performing calculations directly in MySQL queries can be more efficient as it leverages the database's processing power. However, it can make the queries more complex and harder to debug. On the other hand, using PHP for calculations allows for easier debugging and more flexibility in handling errors or edge cases. 

// Example of using PHP for calculations instead of MySQL queries

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Query the database
$query = "SELECT * FROM table";
$result = $mysqli->query($query);

// Fetch the data and perform calculations in PHP
while ($row = $result->fetch_assoc()) {
    $result = $row['column1'] * $row['column2'];
    
    // Debugging
    echo "Result: " . $result . "<br>";
}

// Close the connection
$mysqli->close();
