How to use namespace properly in php?

Namespace in PHP is used to avoid name conflicts between classes, functions, and constants. To use namespaces properly in PHP, follow these steps:

1. Define a namespace at the beginning of your PHP file using the namespace keyword:

1

namespace MyNamespace;

1. Use the use keyword to import classes, functions, and constants from other namespaces:

1

use AnotherNamespaceAnotherClass;

1. Use the fully qualified class name when instantiating a class from another namespace:

1

$obj = new AnotherNamespaceAnotherClass();

1. To access classes, functions, and constants within the same namespace, you can use the use keyword as well:

1
2

use MyNamespaceMyClass;
$obj = new MyClass();

1. Use the __NAMESPACE__ magic constant to get the current namespace:

1

echo __NAMESPACE__;

By following these steps, you can effectively use namespaces in PHP to organize and manage your code more efficiently.
