Is there any official documentation in the PHP manual that explains the behavior of namespaces in relation to global scope and object instantiation from strings?

To understand the behavior of namespaces in relation to global scope and object instantiation from strings, you can refer to the official PHP manual on namespaces and object instantiation. The manual provides detailed explanations and examples on how namespaces affect global scope and how to instantiate objects using strings with namespaces.

// Example code demonstrating object instantiation from strings with namespaces

// Define a class within a namespace
namespace MyNamespace;
class MyClass {
    public function __construct() {
        echo 'MyClass instantiated from MyNamespace';
    }
}

// Instantiate an object using a string with the namespace
$className = 'MyNamespace\\MyClass';
$obj = new $className();
