Are there any best practices for replacing include/require statements with calls to object-oriented libraries in PHP scripts?

When replacing include/require statements with calls to object-oriented libraries in PHP scripts, it is important to ensure that the classes are properly autoloaded using an autoloader. This helps in organizing and managing dependencies efficiently. Additionally, using namespaces can help prevent naming conflicts and make the code more readable.

// Autoloader function to load classes
spl_autoload_register(function($class) {
    $file = __DIR__ . '/classes/' . str_replace('\\', '/', $class) . '.php';
    if (file_exists($file)) {
        require_once $file;
    }
});

// Example of using an object-oriented library
use MyNamespace\MyClass;

$myObject = new MyClass();
$myObject->doSomething();
