Fatal Error: Silex Application::share()

Question

I am developing an API in Silex and while trying to test it on my server, I am encountering following error:

Fatal error: Call to Undefined method Silex Application::share() in /var/www/App/Config/config.php on line 24

And the function share is a function of the Silex but I don’t know the reason for this mistake.

The line of code he’s pointing at is this one:

'users' => $app->share(function($app) {
       $em = $app['orm.em'];
       return $em->getRepository('\App\Model\Entity\User');
})

I would like to apologize in advance: I’m not a Portuguese speaker, I’m just using Google Translate to translate my answer.

As other people have indicated that you seem to be reading the documentation for Silex 1.x, but what you have installed is Silex 2.x.

One of the main differences between the two versions is that the dependency injection container that Silex uses - Pimple - was incorporated into Silex itself in 1.0, while in 2.0 it is treated as a separate application (and probably this is a good idea). Share is actually a Pimple method, not a Silex method.

Well, I say it’s a Pimple method ... era a Pimple method. In Pimple 1.x, all dependencies were transient objects, unless the method was specifically used share to make it a Singleton. In the current version of Pimple (3.x), the default has been changed and all dependencies are automatically singletons by default, so the method share is redundant.

What you need to do is follow the Silex 2.x and Pimple 3.x documentation when configuring your application.

References:

(Silex 1.x / Pimple 1.x) By default, each time you receive a service, Pimple returns a new instance. If you want the same instance to be returned for all calls, involve your anonymous function with the method share()

(Silex 2.x / Pimple 3.x) By default, each time you receive a service, Pimple returns the same instance.
