What role does the namespace statement play in PHP classes and how can it impact autoloading?

The namespace statement in PHP classes helps to organize and differentiate classes with the same name. When using namespaces, it is important to ensure that the namespace corresponds to the directory structure of the files. This can impact autoloading as the autoloader needs to correctly map the namespace to the file path for classes to be autoloaded successfully. 

// Example of using namespaces in PHP classes to organize and autoload classes

// File: MyClass.php
namespace MyNamespace;

class MyClass {
    public function __construct() {
        echo "MyClass instantiated!";
    }
}

// File: autoload.php
spl_autoload_register(function($class) {
    $file = str_replace('\\', '/', $class) . '.php';
    require_once $file;
});

// File: index.php
require_once 'autoload.php';

use MyNamespace\MyClass;

$myClass = new MyClass();
