Add {} around $run[1]: This uses an anonymous class which is available since PHP >= 7.0

<?php
$run = [];
$run[0] = new Class {

    public function myMethod(){
        return 'Hello world';   
    }

};
$run[1] = 'myMethod';


$class = new $run[0]();
echo $class->{$run[1]}(); //Returns Hello world

@123onetwothree Yes it will work. The thing that won't work is how I created the anonymous class in $run[0]

and if i have an array with parameters how can i pass that array to the function ? can i use call_user_func_array() ?

@SagarGuhe What do you mean this might not work in PHP7 ? The only version in which above code will work is PHP 7.

@123onetwothree I would use the splat operator.
