PHP 爬蟲庫：Goutte

Goutte 是一個抓取網站數據的 PHP 庫。它提供了一個優雅的 API，這使得從遠程頁面上選擇特定元素變得簡單。

Require the Goutte phar file to use Goutte in a script:

require_once '/path/to/goutte.phar'; 

Create a Goutte Client instance (which extends SymfonyComponentBrowserKitClient):

use Goutte\Client; $client = new Client(); 

Make requests with the request() method:

$crawler = $client->request('GET', 'http://www.symfony-project.org/'); 

The method returns a Crawler object (SymfonyComponentDomCrawlerCrawler).

點擊鏈接：

$link = $crawler->selectLink('Plugins')->link(); $crawler = $client->click($link); 

提交表單：

$form = $crawler->selectButton('sign in')->form(); 
$crawler = $client->submit($form, array('signin[username]' => 'fabien', 'signin[password]' => 'xxxxxx')); 

$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());
