What suggestions can be provided to improve the efficiency and effectiveness of the PHP code for updating the MySQL database?

Issue: To improve the efficiency and effectiveness of updating the MySQL database using PHP, it is recommended to use prepared statements to prevent SQL injection attacks and improve performance. 

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Prepare the SQL statement
$stmt = $mysqli->prepare("UPDATE table_name SET column1 = ? WHERE id = ?");

// Bind parameters
$stmt->bind_param("si", $value1, $id);

// Set the parameters
$value1 = "new_value";
$id = 1;

// Execute the statement
$stmt->execute();

// Close the statement and connection
$stmt->close();
$mysqli->close();
