Graby helps you extract article content from web pages

Why this fork ?

Full-Text RSS works great as a standalone application. But when you need to encapsulate it in your own library it's a mess. You need this kind of ugly thing:

$article = 'http://www.bbc.com/news/entertainment-arts-32547474';
$request = 'http://example.org/full-text-rss/makefulltextfeed.php?format=json&url='.urlencode($article);
$result  = @file_get_contents($request);

Also, if you want to understand how things work internally, it's really hard to read and understand. And finally, there are no tests at all.

That's why I made this fork:

  1. Easiest way to integrate it (using composer)
  2. Fully tested
  3. (hopefully) better to understand
  4. A bit more decoupled

How to use it

Note These instructions are for development version of Graby, which has an API incompatible with the stable version. Please check out the README in the 2.x branch for usage instructions for the stable version.


  • PHP >= 7.4
  • Tidy & cURL extensions enabled


Add the lib using Composer:

composer require 'j0k3r/graby dev-master' php-http/guzzle7-adapter

Why php-http/guzzle7-adapter? Because Graby is decoupled from any HTTP client implementation, thanks to HTTPlug (see that list of client implementation).

Graby is tested & should work great with:

  • Guzzle 7 (using php-http/guzzle7-adapter)
  • Guzzle 5 (using php-http/guzzle5-adapter)
  • cURL (using php-http/curl-client)

Note: if you want to use Guzzle 6, use Graby 2 (support has dropped in v3 because of dependencies conflicts, which does not happen with Guzzle 5 🤷)

Retrieve content from an url

Use the class to retrieve content:

use Graby\Graby;

$article = 'http://www.bbc.com/news/entertainment-arts-32547474';

$graby = new Graby();
$result = $graby->fetchContent($article);

var_dump($result->getResponse()->getStatus()); // 200
var_dump($result->getHtml()); // "[Fetched and readable content…]"
var_dump($result->getTitle()); // "Ben E King: R&B legend dies at 76"
var_dump($result->getLanguage()); // "en-GB"
var_dump($result->getDate()); // "2015-05-01T16:24:37+01:00"
var_dump($result->getAuthors()); // ["BBC News"]
var_dump((string) $result->getResponse()->getEffectiveUri()); // "http://www.bbc.com/news/entertainment-arts-32547474"
var_dump($result->getImage()); // "https://ichef-1.bbci.co.uk/news/720/media/images/82709000/jpg/_82709878_146366806.jpg"
var_dump($result->getSummary()); // "Ben E King received an award from the Songwriters Hall of Fame in …"
var_dump($result->getIsNativeAd()); // false
var_dump($result->getResponse()->getHeaders()); /*
  'server' => ['Apache'],
  'content-type' => ['text/html; charset=utf-8'],
  'x-news-data-centre' => ['cwwtf'],
  'content-language' => ['en'],
  'x-pal-host' => ['pal074.back.live.cwwtf.local:80'],
  'x-news-cache-id' => ['13648'],
  'content-length' => ['157341'],
  'date' => ['Sat, 29 Apr 2017 07:35:39 GMT'],
  'connection' => ['keep-alive'],
  'cache-control' => ['private, max-age=60, stale-while-revalidate'],
  'x-cache-action' => ['MISS'],
  'x-cache-age' => ['0'],
  'x-lb-nocache' => ['true'],
  'vary' => ['X-CDN,X-BBC-Edge-Cache,Accept-Encoding'],

In case of error when fetching the url, graby won't throw an exception but will return information about the error (at least the status code):

var_dump($result->getResponse()->getStatus()); // 200
var_dump($result->getHtml()); // "[unable to retrieve full-text content]"
var_dump($result->getTitle()); // "BBC - 404: Not Found"
var_dump($result->getLanguage()); // "en-GB"
var_dump($result->getDate()); // null
var_dump($result->getAuthors()); // []
var_dump((string) $result->getResponse()->getEffectiveUri()); // "http://www.bbc.co.uk/404"
var_dump($result->getImage()); // null
var_dump($result->getSummary()); // "[unable to retrieve full-text content]"
var_dump($result->getIsNativeAd()); // false
var_dump($result->getResponse()->getHeaders()); // […]

The date result is the same as displayed in the content. If date is not null in the result, we recommend you to parse it using date_parse (this is what we are using to validate that the date is correct).

Retrieve content from a prefetched page

If you want to extract content from a page you fetched outside of Graby, you can call setContentAsPrefetched() before calling fetchContent(), e.g.:

use Graby\Graby;

$article = 'http://www.bbc.com/news/entertainment-arts-32547474';

$input = '<html>[...]</html>';

$graby = new Graby();
$result = $graby->fetchContent($article);

Cleanup content

Since the 1.9.0 version, you can also send html content to be cleanup in the same way graby clean content retrieved from an url. The url is still needed to convert links to absolute, etc.

use Graby\Graby;

$article = 'http://www.bbc.com/news/entertainment-arts-32547474';
// use your own way to retrieve html or to provide html
$html = ...

$graby = new Graby();
$result = $graby->cleanupHtml($html, $article);

Use custom handler & formatter to see output log

You can use them to display graby output log to the end user. It's aim to be used in a Symfony project using Monolog.

Define the graby handler service (somewhere in a service.yml):

    # ...
        class: Graby\Monolog\Handler\GrabyHandler

Then define the Monolog handler in your app/config/config.yml:

            type: service
            id: graby.log_handler
            # use "debug" to got a lot of data (like HTML at each step) otherwise "info" is fine
            level: debug
            channels: ['graby']

You can then retrieve logs from graby in your controller using:

$logs = $this->get('monolog.handler.graby')->getRecords();

Timeout configuration

If you need to define a timeout, you must create the Http\Client\HttpClient manually, configure it and inject it to Graby\Graby.

  • For Guzzle 5:

    use Graby\Graby;
    use GuzzleHttp\Client as GuzzleClient;
    use Http\Adapter\Guzzle5\Client as GuzzleAdapter;
    $guzzle = new GuzzleClient([
        'defaults' => [
            'timeout' => 2,
    $graby = new Graby([], new GuzzleAdapter($guzzle));
  • For Guzzle 7:

    use Graby\Graby;
    use GuzzleHttp\Client as GuzzleClient;
    use Http\Adapter\Guzzle7\Client as GuzzleAdapter;
    $guzzle = new GuzzleClient([
        'timeout' => 2,
    $graby = new Graby([], new GuzzleAdapter($guzzle));

Full configuration

This is the full documented configuration and also the default one.

$graby = new Graby([
    // Enable or disable debugging.
    // This will only generate log information in a file (log/graby.log)
    'debug' => false,
    // use 'debug' value if you want more data (HTML at each step for example) to be dumped in a different file (log/html.log)
    'log_level' => 'info',
    // If enabled relative URLs found in the extracted content are automatically rewritten as absolute URLs.
    'rewrite_relative_urls' => true,
    // If enabled, we will try to follow single page links (e.g. print view) on multi-page articles.
    // Currently this only happens for sites where single_page_link has been defined

    'singlepage' => true,
