$this->arg = $arg;
}
function __get($name) {
if ($this->data === false) {
$this->data = call_user_func_array($this->func, $this->arg);

return $this->data->$name;
}
}
<?php
require_once "./util/async.class.php";
class Goods {
public $g1 = 'hello world';

function __construct($str) {
$this->g2 = $str;
}
}
class Dev {
public $d1 = 'this is d1';
public $d2 = 'this is d2';
function __construct($str) {
$this->goods = new _async(function($arg){return new Goods($arg);}, [$str]);
}
}
