How to unset scoped instances from the DI Container in laravel 5.3?
In Laravel, the Dependency Injection (DI) container is used to manage and provide instances of services, bindings, and interfaces to the application. When you define a scoped instance in Laravel, it means that the container will create a new instance of the given class each time the container is asked for an instance of that class within the given scope.
To unset or remove a scoped instance from the DI container in Laravel 5.3, you can follow these steps:
- First, you need to get the instance of the container from the application instance. You can do this by using the
app()
helper function:
$container = app();
- Once you have the container instance, you can use the
instance()
method to get the scoped instance that you want to unset. This method returns the current instance of the given class from the container:
$scopedInstance = $container->instance('App\Services\ScopedService');
Replace App\Services\ScopedService
with the actual class name of the scoped instance that you want to unset.
- To unset the scoped instance, you can use the
bind()
method of the container and pass the class name and a null value as arguments. This will effectively remove the binding for the given class and any future requests for instances of that class within the given scope will result in a new instance being created:
$container->bind('App\Services\ScopedService', null);
- Finally, you can verify that the scoped instance has been unset by checking if the container returns a new instance when asked for it:
$newInstance = $container->make('App\Services\ScopedService');
if ($newInstance !== $scopedInstance) {
// The scoped instance has been unset
}
By following these steps, you can unset or remove scoped instances from the DI container in Laravel 5.3. Keep in mind that unseting a scoped instance will affect any future requests for instances of that class within the given scope, so make sure that you understand the implications of this action before proceeding.
