What are some best practices for handling namespaces when instantiating objects in PHP?

When instantiating objects in PHP, it is important to handle namespaces correctly to avoid conflicts and ensure proper class resolution. One best practice is to use the fully qualified class name when instantiating objects, especially if the classes are in different namespaces. This helps prevent ambiguity and ensures that the correct class is instantiated.

use Namespace1\ClassA;
use Namespace2\ClassB;

// Instantiate ClassA using the fully qualified class name
$objA = new Namespace1\ClassA();

// Instantiate ClassB using the fully qualified class name
$objB = new Namespace2\ClassB();
