use DrupalnodeEntityNode;



function abc($v) {

  $node = DrupalnodeEntityNode::load($v);

  print_r($node);

}

The array structure of $node is as given below

DrupalnodeEntityNode Object (

[in_preview] => 



[values:protected] => Array

    (





   [nid] => Array

        (

            [x-default] => 166

        )



    [vid] => Array

        (

            [x-default] => 180

        )



    [type] => Array

        (

            [x-default] => sections

        )



    [uuid] => Array

        (

            [x-default] => 7759efc9-cfff-4d58-b392-8d60b9903323

        )



    [langcode] => Array

        (

            [x-default] => en

        )

As mentioned in the comment of @Hudri Node is an object not an array.

In Drupal 8 there are two ways to get the value of a field.

1. 
   $node->field_name->value


2. $node->get("field_name")->getValue()

In your case you can get the nid and title like below:

$nid = $node->id();

$title = $node->label();

or

$title = $node->getTitle();

To read about objected-oriented programming conventions In Drupal 8 check this blog article: Drupal 8 API: objected-oriented programming conventions.

you can get the node id like this :

$nid = $node->id();

and for the title :

$title = $node->label();

You can get the node id and node title values by using Node::load function.

use DrupalnodeEntityNode;

function abc($v)
{

$node = Node::load($v);



$strNodeId =  $node->nid->value;



$strNodeTitle = $node->title->value;



echo 'Id: '.$strNodeId;



echo 'Title: '.$strNodeTitle;

exit();

}
