What considerations should be made when deciding between ORM and Query Builder for handling database operations in PHP projects?

When deciding between ORM and Query Builder for handling database operations in PHP projects, consider factors such as complexity of queries, performance requirements, familiarity with the tools, scalability needs, and maintainability of the codebase. ORM is suitable for simpler queries and faster development, while Query Builder allows for more control over SQL queries and better performance optimization.

// Example of using ORM (Doctrine ORM)
$user = $entityManager->find('User', $userId);
$user->setName('John Doe');
$entityManager->flush();

// Example of using Query Builder (Doctrine Query Builder)
$qb = $entityManager->createQueryBuilder();
$qb->update('User', 'u')
   ->set('u.name', ':name')
   ->setParameter('name', 'John Doe')
   ->where('u.id = :id')
   ->setParameter('id', $userId)
   ->getQuery()
   ->execute();
