How to check if a record is new in Laravel?

Question

I recently started using Eloquent.

When I used PHP Active Record, there was a nice function that checked if a record was loaded from the database or is a new instan

Answer 1

$article = new Article;
var_dump($article->id); == null

$article = Article::find(1);
var_dump($article->id); == string(1) "1"

so

if ($article->id) {
     // I am existing
} else {
    // I am new
}
