laravel important concepts and implementation methods

Initialization of Application

$app = new Illuminate\Foundation\Application(
    realpath(__DIR__.'/../')
);

Register basic bindings

$this->instance();

Register the corresponding alias in the instances array

$this->registerBaseBindings();

Bind app and Container to an instance array, and the implementations are both instances of Application

$this->instance('app', $this);
$this->instance('Illuminate\Container\Container', $this);

Register a basic service provider

$this->register()

Put the registered provider in $this->serviceProviders[]

$this->registerBaseServiceProviders()

Put the registered provider in $this->serviceProviders[] and directly trigger the register() method in the provider. If the application has been booted, then trigger the boot method in the provider.

$this->register(new EventServiceProvider($this));
$this->register(new RoutingServiceProvider($this));

Register core container aliases

$this->registerCoreContainerAliases()

Register the class address in $this->aliases, why?

Implementation of facade

is the class name implemented by class_alias

When the app starts, the kernel passes the handle, triggers the bootstrapwith in the app, and triggers the bootstrap method in the class implementation in each list

bootstrapwith loads a list of all bootstrap needs,

A bootstrap is triggered in RegisterFacade in the list, then AliasLoader loads the aliases configuration in config and executes register

register is registered through autoload, and the internal implementation is through class_alias

Loading of helpers helper functions

Through autoload, autoload_files are loaded, and then require directly
