Goutte 介绍
Goutte 是一个抓取网站数据的 PHP 库。它提供了一个优雅的 API，这使得从远程页面上选择特定元素变得简单。
示例代码：
require_once '/path/to/goutte.phar';
use Goutte\Client;
//发送请求
$client = new Client();
$crawler = $client->request('GET', 'http://www.oschina.net/');
//点击链接
$link = $crawler->selectLink('Plugins')->link();
$crawler = $client->click($link);
//提交表单
$form = $crawler->selectButton('sign in')->form();
$crawler = $client->submit($form, array('signin[username]' => 'fabien', 'signin[password]' => 'xxxxxx'));
//提取数据
$nodes = $crawler->filter('.error_list');
if ($nodes->count())
{
die(sprintf("Authentication error: %s\n", $nodes->text()));
}
printf("Nb tasks: %d\n", $crawler->filter('#nb_tasks')->text());
