What are the advantages of using SQL queries to retrieve current events compared to other methods in PHP?

Using SQL queries to retrieve current events in PHP allows for efficient and optimized data retrieval from a database. By utilizing SQL queries, you can easily filter and sort data based on specific criteria, making it easier to retrieve only the relevant information. This method also ensures data integrity and security by leveraging SQL injection prevention techniques. 

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

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

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

// Retrieve current events using SQL query
$sql = "SELECT * FROM events WHERE event_date >= CURDATE() ORDER BY event_date ASC";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Event: " . $row["event_name"]. " - Date: " . $row["event_date"]. "<br>";
    }
} else {
    echo "No current events found.";
}

$conn->close();
