Binding an Instance 166 Binding a Singleton to the Service Container 166 Introduction 167 Using the Service Container as a Dependency Injection Container 167 Chapter 57: Socialite 168 Examples 168 Installation Create a new Eloquent model class make:policy Create a new policy class make:provider Create a new service provider class make:request Create a new form request class make:seeder Create a new seeder class will be available in all views under the name $shareddata. View::share is typically called in a service provider, or perhaps in the constructor of a controller, so the data will be shared in views returned

function getTypeName() has been dropped. Use PHP’s get_debug_type() instead. The dependency on league/container was updated to 4.x. This will require the addition of typehints to your ServiceProvider implementations version 4.4.0: The ServerRequest is available via DI. So you can get it from container or use it as a dependency for your service. Some of the duties ServerRequest performs include: Processing the GET, address. Trusting Proxy Headers If your application is behind a load balancer or running on a cloud service, you will often get the load balancer host, port and scheme in your requests. Often load balancers

calling this process Experimental Features. Core Experimental support for a Dependency Injection container was added. Console ConsoleIo::comment() was added. This method formats text with a blue foreground and IntegrationTestCaseTrait. This method enables services injected with the Dependency Injection container to be replaced with mock or stub objects. View Context classes now include the comment, null, CakePHP’s dependency on league/container was bumped to ^4.1.1. While the DI container is marked as experimental, this upgrade could require you to upgrade your service provider definitions. Database
