What is the purpose of using PDO Statements in PHP?

Using PDO Statements in PHP allows for secure and efficient interaction with a database. PDO Statements help prevent SQL injection attacks by properly escaping input data and separating SQL logic from data values. Additionally, PDO Statements provide a consistent interface for interacting with different types of databases, making it easier to switch between database systems if needed. 

// Example of using PDO Statements in PHP

// Connect to database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare a SQL statement
$stmt = $pdo->prepare('SELECT * FROM users WHERE id = :id');

// Bind parameters
$stmt->bindParam(':id', $userId, PDO::PARAM_INT);

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

// Fetch the results
$user = $stmt->fetch(PDO::FETCH_ASSOC);
