Add method in an std object in php

Question

Is it possible to add a method/function in this way, like

$arr = array(
    "nid"=> 20,
    "title" => "Something",
    "value" => "Something else",
    "my_method" => function($arg){....}
);

or maybe like this

$node = (object) $arr;
$node->my_method=function($arg){...};

and if it's possible then how can I use that function/method?

Answer 1

This is now possible to achieve in PHP 7.1 with anonymous classes

$node = new class {
    public $property;

    public function myMethod($arg) { 
        ...
    }
};

// and access them,
$node->property;
$node->myMethod('arg');
