When designing a PHP application, what are some strategies for handling rankings or positions that are calculated based on other fields in the database?

When designing a PHP application that requires calculating rankings or positions based on other fields in the database, one strategy is to use SQL queries to calculate the rankings dynamically based on the desired criteria. This can be achieved by using functions like `ROW_NUMBER()` or `RANK()` in SQL queries to assign rankings based on specific fields. Another approach is to retrieve the data from the database and then calculate the rankings in PHP code by sorting and iterating through the results. 

// Example using SQL query to calculate rankings based on a specific field
$query = "SELECT id, name, score, 
          ROW_NUMBER() OVER (ORDER BY score DESC) AS ranking
          FROM players";
$result = mysqli_query($connection, $query);

while($row = mysqli_fetch_assoc($result)) {
    echo "Player: " . $row['name'] . " - Score: " . $row['score'] . " - Ranking: " . $row['ranking'] . "<br>";
}
