How can PHP be optimized to handle the scoring and tracking of points for players in a tournament system with multiple rounds?

To optimize PHP for scoring and tracking points in a tournament system with multiple rounds, you can create a database structure to store player information, scores, and round results. Use PHP functions to calculate and update scores based on the results of each round. Implement a system for tracking player progress and displaying rankings. 

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "tournament_system";

$conn = new mysqli($servername, $username, $password, $dbname);

// Function to calculate and update player scores
function updateScores($player_id, $round_id, $score) {
    global $conn;

    $sql = "UPDATE player_scores SET score = score + $score WHERE player_id = $player_id AND round_id = $round_id";
    $conn->query($sql);
}

// Function to get player rankings
function getPlayerRankings() {
    global $conn;

    $sql = "SELECT player_id, SUM(score) AS total_score FROM player_scores GROUP BY player_id ORDER BY total_score DESC";
    $result = $conn->query($sql);

    $rankings = array();
    while($row = $result->fetch_assoc()) {
        $rankings[] = $row;
    }

    return $rankings;
}
