How can PHP developers ensure secure database operations, such as deleting records, using modern database connection methods like mysqli or PDO?

To ensure secure database operations like deleting records, PHP developers should use prepared statements with parameterized queries when interacting with the database. This helps prevent SQL injection attacks by separating SQL code from user input. By using modern database connection methods like mysqli or PDO, developers can easily implement this security measure. 

// Using PDO for secure database operations
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$id = $_POST['id']; // Assuming this is the record ID to be deleted

$stmt = $pdo->prepare("DELETE FROM mytable WHERE id = :id");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
