How can you combine a namespace with a variable in PHP?

To combine a namespace with a variable in PHP, you can use the concatenation operator (.) to append the variable to the namespace string. This is useful when you want to dynamically access classes or functions within a specific namespace using a variable. Example: 

<?php
namespace MyNamespace;

$className = 'MyClass';
$fullClassName = __NAMESPACE__ . '\\' . $className;

$instance = new $fullClassName();
$instance->someMethod();
?>
