Goutte, a simple PHP Web Scraper

Goutte is a screen scraping and web crawling library for PHP.

Goutte provides a nice API to crawl websites and extract data from the HTML/XML responses.

Requirements

Goutte depends on PHP 5.5+ and Guzzle 6+.

Tip

If you need support for PHP 5.4 or Guzzle 4-5, use Goutte 2.x (latest phar).

If you need support for PHP 5.3 or Guzzle 3, use Goutte 1.x (latest phar).

Installation

Add fabpot/goutte as a require dependency in your composer.json file:

composer require fabpot/goutte

Usage

Create a Goutte Client instance (which extends Symfony\Component\BrowserKit\Client):

use Goutte\Client;

$client = new Client();

Make requests with the request() method:

// Go to the symfony.com website

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

The method returns a Crawler object (Symfony\Component\DomCrawler\Crawler).

Fine-tune cURL options:

$client->getClient()->setDefaultOption('config/curl/'.CURLOPT_TIMEOUT, 60);

Click on links:

// Click on the "Security Advisories" link

$link = $crawler->selectLink('Security Advisories')->link();

$crawler = $client->click($link);

Extract data:

// Get the latest post in this category and display the titles

$crawler->filter('h2 > a')->each(function ($node) {

print $node->text()."\n";

});

Submit forms:

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

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

$form = $crawler->selectButton('Sign in')->form();

$crawler = $client->submit($form, array('login' => 'fabpot', 'password' => 'xxxxxx'));

$crawler->filter('.flash-error')->each(function ($node) {

print $node->text()."\n";

});
