you can also save functions in an array:

arrayFuncs[$name] = $function;
    }
    //
    public function callFunc($namefunc,$params=false){
        if(!isset($this->arrayFuncs[$namefunc])){
            return 'no function exist';
        }
        if(is_callable($this->arrayFuncs[$namefunc])){
            return call_user_func($this->arrayFuncs[$namefunc],$params);
        }
    }

}
$foo = new Foo();

//Save function on array variable with params
$foo->addFunc('my_function_call',function($params){
    return array('data1'=>$params['num1'],'data2'=>'qwerty','action'=>'add');
});
//Save function on array variable
$foo->addFunc('my_function_call2',function(){
    return 'a simple function';
});
//call func 1
$data = $foo->callFunc('my_function_call',array('num1'=>1224343545));
var_dump($data);
//call func 2
$data = $foo->callFunc('my_function_call2');
var_dump($data);
?>
