Simple example of DI autowiring in Laminas MVC

[froschdesign]

Hello and welcome to our forums!

@stark

I am reading in the docs that Laminas-DI supports autowiring out of the box.

If I follow your code examples, you don’t need laminas-di.

In other frameworks like Laravel or Symfony, if I create a new class and I pass it to a constructor of another class it just gets injected. Does it work the same in Laminas?

Sure, use the reflection-based factory of laminas-servicemanager which is already present in a laminas-mvc application. For your controller example this means:

return [
    'factories' => [
        Controller\AdvertController::class => \Laminas\ServiceManager\AbstractFactory\ReflectionBasedAbstractFactory::class,
    ],
];

The second example contains some more preparation therefore a separate factory class is recommended here. Then the configuration can also be cached.

You can find more examples of the usage of the reflection-based factory in the tutorials:

I am kind of evaluating Laminas/Mezzio (among other frameworks) as a candidate to rewrite a ZF1 application…

Then Mezzio is the right candidate, because it has a low entry and can handle the migration from ZF1. See:

Migration de Zf 1.11 vers laminas

Correct, there is no automated migration via script or something else. Some approaches and concepts are too different between version 1 and version 2 of ZF. The topic “dependency injection”, for example, is missing in ZF1. Also the old registry implemented via singleton pattern with global state. These are all old habits and bad practices that have been cut off. My advice for old ZF1 application is to find a way for a soft migration. This means, for example, to clean up all controllers, create…
