How can the PHP script be optimized for better performance when interacting with the database?

To optimize the PHP script for better performance when interacting with the database, you can use prepared statements instead of directly executing SQL queries. Prepared statements can improve performance by reducing the overhead of repeatedly parsing and compiling SQL queries. 

// Using prepared statements to interact with the database
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
