What are the advantages of using SQL in conjunction with PHP for managing tournament data compared to plain PHP?

Using SQL in conjunction with PHP for managing tournament data offers several advantages over using plain PHP. SQL allows for efficient storage, retrieval, and manipulation of data, making it easier to organize and query tournament information. Additionally, SQL provides built-in security features to help prevent SQL injection attacks. By combining SQL with PHP, developers can create dynamic and interactive tournament management systems with ease. 

// Example PHP code snippet using SQL to manage tournament data

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

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query to retrieve tournament data
$sql = "SELECT * FROM tournaments";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Tournament ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
