我尝试启动:cfx run但我收到以下错误:

(C:\Users\michal smoczyk\Downloads\addon-sdk-1.14) C:\Users\michal smoczyk\Downloads\addon-sdk-1.14\my-addon>cfx run

我有这部分代码:

class FTPClient
{
    public function __construct() {
        $args_num=func_num_args();
        echo $args_num;
        $this->{"__construct".($args_num===0 ? '' : $args_num)}(func_get_args());
    }

    function __call($name,$args) {
        echo $name,count($args),'<br/>';
    }

    public function open() {
        echo 'open';
    }
}
    $o = new FTPClient('127.0.0.1','user','pass');
    $o = new FTPClient();
    $o = new FTPClient('127.0.0.1','user');
    $o->close();

输出看起来像这样:

3__construct31
01__construct11 //Don't understand how this output came together?!
2__construct21
close0

有人会这么善良,可以解释一下这个输出的第二行吗？

是否可以以编程方式在 Magento2 中创建分组产品？有 Magento1 的示例，但没有 Magento2 的示例。

你能提供一些例子吗？

在这样的代码的safari扩展中是否有任何等价物:

chrome.tabs.getSelected(null,function(tab) { 
        chrome.tabs.reload(tab.id);
    });
This code comes from Chrome. 

我想将此代码放到global.html中.我希望在扩展安装后立即重新加载页面.
