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\" => \"Somethi

Since PHP 7 it is also possible to directly invoke an anonymous function property:

$obj = new stdClass;
$obj->printMessage = function($message) { echo $message . "\n"; };
echo ($obj->printMessage)('Hello World'); // Hello World

Here the expression $obj->printMessage results in the anonymous function which is then directly executed with the argument 'Hello World'. It is however necessary to put the function expression in paranetheses before invoking it so the following will still fail:

echo $obj->printMessage('Hello World'); 
// Fatal error: Uncaught Error: Call to undefined method stdClass::printMessage()
