get protected attribute by parameter referencing name?

Question

lets say:

class myclass{
     protected $info;
     protected $owner;
     __construct(){
        $this->info = 'nothing';
        $this->owner = 'nobody';
    }
    function getProp($string){
        return $this->$string;
    }
}

But its not working, is it not posible? its not returning anything or showing errors

It works fine, but you're missing the function keyword in front of __construct. This outputs "nothing":

<?php

class myclass{
     protected $info;
     protected $owner;

    function __construct(){
        $this->info = 'nothing';
        $this->owner = 'nobody';
    }
    function getProp($string){
        return $this->$string;
    }
}

$test = new myclass();
echo $test->getProp('info');
