How can the use of prepared statements in PHP scripts improve the efficiency and security of database operations like INSERT and UPDATE?

Using prepared statements in PHP scripts can improve efficiency and security of database operations like INSERT and UPDATE by separating SQL logic from data, which prevents SQL injection attacks. Prepared statements also allow for the reuse of query templates, reducing the overhead of parsing SQL queries each time they are executed. 

// Using prepared statements for INSERT operation
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);
$stmt->execute();
