<?php

// set a value 
$theCount = 123;
// set a string that happens to be the same name as the 
// previous (unrelated) value
$someString = 'theCount';
// print out the string... oh... WAT.
echo $$someString; // echo's 123
echo "\n";


class Foo {
  public function bar(){
    return "hello world";
  }

// intended usage
$foo = new Foo();
echo $foo->bar();
echo "\n";

// assign some strings
$klass = 'Foo';
$method = 'bar';
// make a new... wait...wtf... that didnt exist so you must
// want me to make a new Foo instance, ok, lets do that.
$foo2 = new $klass();
// attempt to call an arbitrary string method on the 
// auto-loaded instance (which was also pulled from a string)
echo $foo2->$method();
