我有这段代码:
require ('vendor/autoload.php');
use Goutte\Client;
use GuzzleHttp\Client as GuzzleClient;
$goutteClient = new Client();
$guzzleClient = new GuzzleClient(array(
'timeout' => 6000,
));
$goutteClient->setClient($guzzleClient);
$crawler = $goutteClient->request('GET', http://www.cophieu68.vn/stockonline_node.php?stcid=1);
// Get the latest post in this category and display the titles
$news = $crawler->filter('table#board_online>tbody>tr')->nextAll()->nextAll()->each(function ($node) {
// print_r($node->text());
return [
'v1' => $node->filter('td')->eq(0)->text(),
'v2' => $node->filter('td')->eq(1)->text(),
'v3' => $node->filter('td')->eq(2)->text(),
'v12' => $node->filter('td')->eq(3)->text(),
'v14' => $node->filter('td')->eq(4)->text(),
'v16' => $node->filter('td')->eq(5)->text(),
'v12' => $node->filter('td')->eq(6)->text(),
'v13' => $node->filter('td')->eq(7)->text(),
'v15' => $node->filter('td')->eq(8)->text(),
'v16' => $node->filter('td')->eq(9)->text(),
'v17' => $node->filter('td')->eq(10)->text(),
'v18' => $node->filter('td')->eq(11)->text(),
];
});
print_r($news);
显示消息:
