用Goutte抓取时PHP返回数组

Question

我正在尝试使用goutte返回一个项目数组,我可以将它们打印出来但我希望它们在数组中,就像API一样.这是示例代码.我正在使用Laravel 5.1.

public function index()
{
    $posts = array();
    $client = new Client();
    $crawler = $client->request('GET', 'http://www.icetimux.com');

    $crawler->filter('h2 > a')->each(function ($node) use ($posts){
        // print $node->text(); //this prints them, needs to return as an array :(
        array_push($posts, $node->text());
    });
    return $posts;
}

我得到的只是一个空数组.

public function index()
{

    $crawler = $client->request('GET', 'http://www.icetimux.com');

    return $result = $crawler->filter('h2 > a')->each(function ($node){
        return $posts[] = $node->text();
    });
}
