# Scraping Social Media Meta Tags

Scraping social media sharing tags from a website can be done using the following methods. The exact result set depends on the provided tags. All tags are included, as long as these are in the prefixed namespace (e.g. twitter: for Twitter Cards).

# Open-Graph (OG) Data

Fetching open-graph data can be done:

$web = new \spekulatius\phpscraper();

/**
 * Navigate to the test page. Page contains:
 *
 * <!-- open graph example -->
 * <meta property="og:site_name" content="Lorem ipsum" />
 * <meta property="og:type" content="website" />
 * <meta property="og:title" content="Lorem Ipsum" />
 * <meta property="og:description" content="Lorem ipsum dolor etc." />
 * <meta property="og:url" content="https://test-pages.phpscraper.de/lorem-ipsum.html" />
 * <meta property="og:image" content="https://test-pages.phpscraper.de/assets/cat.jpg" />
 *
 * @see https://test-pages.phpscraper.de/og/example.html
 */
$web->go('https://test-pages.phpscraper.de/og/example.html');

// Should print 'Lorem Ipsum'
echo $web->openGraph['og:title'];

// Should print 'Lorem ipsum dolor etc.'
echo $web->openGraph['og:description'];

// the whole set:
$data = $web->openGraph;

/**
 * $data now contains:
 *
 * [
 *     'og:site_name' => 'Lorem ipsum',
 *     'og:type' => 'website',
 *     'og:title' => 'Lorem Ipsum',
 *     'og:description' => 'Lorem ipsum dolor etc.',
 *     'og:url' => 'https://test-pages.phpscraper.de/lorem-ipsum.html',
 *     'og:image' => 'https://test-pages.phpscraper.de/assets/cat.jpg',
 * ]
 */

TIP

If not data was found, the array will be returned empty.

# Twitter Card

Parsing the Twitter Card works similarly:

$web = new \spekulatius\phpscraper();

/**
 * Navigate to the test page. The page contains the following Twitter Card:
 *
 * <!-- Twitter card -->
 * <meta name="twitter:card" content="summary_large_image" />
 * <meta name="twitter:title" content="Lorem Ipsum" />
 * <meta name="twitter:description" content="Lorem ipsum dolor etc." />
 * <meta name="twitter:url" content="https://test-pages.phpscraper.de/lorem-ipsum.html" />
 * <meta name="twitter:image" content="https://test-pages.phpscraper.de/assets/cat.jpg" />
 *
 * @see https://test-pages.phpscraper.de/twittercard/example.html
 */
$web->go('https://test-pages.phpscraper.de/twittercard/example.html');

// Should print out 'summary_large_image'
echo $web->twitterCard['twitter:card']);

// Should print out 'Lorem Ipsum'
echo $web->twitterCard['twitter:title']);

// The whole set.
$data = $web->twitterCard;

/**
 * $data contains now:
 *
 * [
 *     'twitter:card' => 'summary_large_image',
 *     'twitter:title' => 'Lorem Ipsum',
 *     'twitter:description' => 'Lorem ipsum dolor etc.',
 *     'twitter:url' => 'https://test-pages.phpscraper.de/lorem-ipsum.html',
 *     'twitter:image' => 'https://test-pages.phpscraper.de/assets/cat.jpg',
 * ]
 */

In similar fashion to Open Graph, the array will be empty if no Twitter Card tags have been found.
