What are the benefits of using prepared statements and parameter binding in PHP when interacting with a database?

Using prepared statements and parameter binding in PHP when interacting with a database helps prevent SQL injection attacks by separating SQL logic from user input. Prepared statements also improve performance by allowing the database to compile the SQL query only once and reuse it with different parameters. 

// Example of using prepared statements and parameter binding in PHP
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();
$results = $stmt->fetchAll();
