namespace LibraryName\SubNamespace; class ClassName { // class definition }
use LibraryName\SubNamespace\ClassName; $obj = new ClassName();In this example, we use the "use" statement to import the class "ClassName" from the namespace "LibraryName\SubNamespace". We can then create a new instance of the class using the imported namespace. Package Library: The package library in this example would be the library or package that contains the namespace "LibraryName\SubNamespace". This could be a custom PHP library developed specifically for the project or an external library installed through Composer.
