Laminas View Helper

No need to say, just follow these steps below:

Code

namespace MyApp;

class MyHelper extends \Laminas\View\Helper\AbstractHelper {
    public function __invoke() {
        return $this;
    }

    public function say() {
        return 'Bonjour!';
    }
}

Configuration

'view_helpers' => [
    'aliases' => [
        'myhelper' => \MyApp\MyHelper::class
    ],
    'factories' => [
        \MyApp\MyHelper::class => \Laminas\ServiceManager\Factory\InvokableFactory::class
    ]
]

Note

You can create your own factory class so as your object can access the service manager or do some special prepare for thereof. To make a factory class, just create a class with postfix Factory and implements from interface FactoryInterface.

namespace MyApp;

class AbcFactory implements \Laminas\ServiceManager\FactoryInterface {
    public function __invoke(\Interop\Container\ContainerInterface ContainerInterface $container, $requestedName, array $options = null) {
        ///$container is the service manager
        
        return new MyHelper();
    }
}

Usage

In view scripts:

$this->myhelper();//return MyHelper object
$this->myhelper()->say();//quick access to member function

In other view helpers:

$this->view->myhelper();//return MyHelper object
$this->view->myhelper()->say();//quick access to member function

Happy coding!
