What are some common pitfalls to avoid when working with PHP classes and methods for escaping strings?

One common pitfall when working with PHP classes and methods for escaping strings is not properly sanitizing user input, which can lead to SQL injection attacks. To avoid this, always use prepared statements or parameterized queries when interacting with a database to prevent malicious code execution. 

// Example of using prepared statements to escape strings
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username);
$stmt->execute();
