How to change class?

Question

symfony

the system I am working with returns me an object of the Content type,
this class is hardcoded in logic and there is no way to change it through the configuration parameters,
I need to add a couple of methods of the Content-> getChildren () type to it,
which will make an additional request to the database
I did

class myContent extends Content
{
    public function __construct( $obj )
    {
        foreach ($obj as $key => $value)
        {
            $this->$key = $value;
        }
    }

    public function getChildren()
   { . . .}
}

but I got errors when I pass this object to different methods
- because there are somewhere checks for instanceof
how to solve this problem?
maybe you can just replace the autoload of the original class with mine through the composer?

в вашем коде нет вызова родительского конструктора, может быть в этом проблема?
