What are some potential pitfalls or security risks when using mysql_escape_string in PHP?

Using mysql_escape_string in PHP can lead to SQL injection vulnerabilities if not used properly. It is recommended to use parameterized queries or prepared statements with mysqli or PDO instead for better security. This will help prevent malicious users from injecting harmful SQL code into your queries. 

// Example of using prepared statements with PDO to prevent SQL injection
$pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $username);
$stmt->execute();
$result = $stmt->fetchAll();
