Is it possible to add an anonymous function to an object, and call it within the object. See below for example code. Calling closure assigned to object property directly and Anonymous function for a method of an object describe calling it directly, not within the object. Thank you

class myClass
{
    public function go()
    {
        $this->scope;
    }
}

$myObj=new myClass();
$myObj->scope=function()
{
    echo('Print This!');
};
$myObj->go();

Not sure if it is but you need to define your property first – php_nub_qq Jun 5 at 13:40
@php_nub_qq. No effect when defining the property first. – user1032531 Jun 5 at 13:42

$this->scope needs to called/executed within myClass:go. For example: -

<?php
class Example {
    protected
        $callback;

    public function setCallback($callback) {
        $this->callback = $callback;
    }

    public function invoke() {
        call_user_func($this->callback);
    }
}

$example = new Example;

$example->setCallback(function(){
    echo 'Hello World';
});

$example->invoke();
/*
    Hello World
*/

Thanks Anthony, Seems call_user_func() is what I needed. – user1032531 Jun 5 at 13:47
