how instantiation of a class works for different routes in - Laravel

Perhaps my question is vague, so let me make it clear. I've created a controller file, say, SomeController.php and here in my LoginController I have:

use SomeController;

private $instance;

public function someRouteDefinedInRouteFile() {
   $this->instance = new SomeController; // now $this->instance must have SomeController instance
   return $this->instance;
}

public function someOtherRoute() {
   return $this->instance;  // it must return the instance but it's null
}

If someRouteDefinedInRouteFile() is called $this->instance must have the instance of SomeController. But after calling someAnotherRoute(), $this->instance is null

If you want use a instance in all methods it must be set in constructor or create setter method and call this method in each method that want use instance.

Examples:

1: 

`public function someRouteDefinedInRouteFile(SomeController $instance) {
   $this->instance = $instance; // now $this->instance must have SomeController instance
   return $this->instance;
}

2:

function getInstanceSomeController(){
   return new SomeController;
}

But i don't understand why you need to other controller instance? maybe you will can use library or general class.

This is because these methods are executed during separate requests. If you want to use the same instance, use IoC to inject the class in controller constructor.

protected $istance;
public function __construct(Instance $instance)
{
    $this->instance = $instance;
}

Then you'll be able to use it in any controller's methods.
