What are some alternative approaches to building SQL queries in PHP that are more secure and efficient than the traditional methods shown in the forum thread?

When building SQL queries in PHP, it is important to use parameterized queries to prevent SQL injection attacks and improve efficiency. One alternative approach is to use prepared statements with placeholders for dynamic values, which separate the SQL query from the user input. Another option is to use an ORM (Object-Relational Mapping) library like Doctrine or Eloquent, which abstracts the database interactions and provides a more secure and efficient way to query the database. 

// Using prepared statements with placeholders
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->execute(['username' => $username]);
$results = $stmt->fetchAll();

// Using an ORM like Doctrine
$user = $entityManager->getRepository(User::class)->findOneBy(['username' => $username]);
