In what scenarios is it recommended to perform value manipulation directly during a database query in PHP?

Performing value manipulation directly during a database query in PHP is recommended when you want to retrieve or update data in a specific format before returning it to the application. This can include formatting dates, concatenating strings, or performing calculations on the data directly in the query. 

// Example of performing value manipulation directly during a database query in PHP
$query = "SELECT CONCAT(first_name, ' ', last_name) AS full_name FROM users";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    echo $row['full_name'] . "<br>";
}
