This is a revision of George Mihailhoff's PHP Anonymous Object Class. I stumbled upon this class as I was looking for a way to attach functions to properties in a stdClass. This is not directly possible as there is no __call function inbuilt. And I found this code on a stackoverflow post that George had answered. However the implementation didn'…

AnObj-v2.php

<?php

class AnObj
{
  protected $methods = array();

	public function __construct(array $options)
	{
		
		foreach($options as $key => $opt) {
			//integer, string, float, boolean, array
			if(is_array($opt) || is_scalar($opt)) {
				$this->properties[$key] = $opt;
				unset($options[$key]);
			}
		}

		$this->methods = $options;
		 foreach($this->properties as $k => $value)
      		$this->{$k} = $value;
	}
 
	public function __call($name, $arguments)
	{
		$callable = null;
		if (array_key_exists($name, $this->methods))
			$callable = $this->methods[$name];
		elseif(isset($this->$name))
			$callable = $this->$name;
 
		if (!is_callable($callable))
			throw new BadMethodCallException("Method {$name} does not exists");
 
		return call_user_func_array($callable, $arguments);
	}
}

$person = new AnObj(array(
	"name" => "nick",
	"age" => 23,
	"friends" => ["frank", "sally", "aaron"],
    	"sayHi" => function() {return "Hello there";}
));

echo $person->name . ' - ';
echo $person->age . ' - ';
print_r($person->friends) . ' - ';
echo $person->sayHi();

No you don't. You just need to bind $this to the function. I modified this gist to do this here.
