### Google+ Snippet
[Google indexes Open Graph protocol markup](https://developers.google.com/+/plugins/+1button/#plus-snippet) to populate a Google+ activity post.
+
+## Sample code
+
+### Core Open Graph protocol
+
+Support for structured properties for image, video, and audio objects.
+
+ $image = new OpenGraphProtocolImage();
+ $image->setURL( 'http://example.com/image.jpg' );
+ $image->setSecureURL( 'https://example.com/image.jpg' );
+ $image->setType( 'image/jpeg' );
+ $image->setWidth( 400 );
+ $image->setHeight( 300 );
+
+ $video = new OpenGraphProtocolVideo();
+ $video->setURL( 'http://example.com/video.swf' );
+ $video->setSecureURL( 'https://example.com/video.swf' );
+ $video->setType( OpenGraphProtocolVideo::extension_to_media_type( pathinfo( parse_url( $video->getURL(), PHP_URL_PATH ), PATHINFO_EXTENSION ) ) );
+ $video->setWidth( 500 );
+ $video->setHeight( 400 );
+
+ $audio = new OpenGraphProtocolAudio();
+ $audio->setURL( 'http://example.com/audio.mp3' );
+ $audio->setSecureURL( 'https://example.com/audio.mp3' );
+ $audio->setType('audio/mpeg');
+
+Declare a new `OpenGraphProtocol` object and set some properties. Add structured media objects.
+
+ $ogp = new OpenGraphProtocol();
+ $ogp->setLocale( 'en_US' );
+ $ogp->setSiteName( 'Happy place' );
+ $ogp->setTitle( 'Hello world' );
+ $ogp->setDescription( 'We make the world happy.' );
+ $ogp->setType( 'website' );
+ $ogp->setURL( 'http://example.com/' );
+ $ogp->setDeterminer( 'the' );
+ $ogp->addImage($image);
+ $ogp->addAudio($audio);
+ $ogp->addVideo($video);
+
+Output your OpenGraphProtocol object as HTML `` elements. Default configuration uses the `property` attribute from RDFa. Change to `name` if you prefer HTML specification compliance and consuming agents support the `name` attribute as a `property` fallback.
+
+ $ogp->toHTML();
+
+### Global objects
+
+Build global objects and attributes. Set time values using either an ISO 8601 formatted string or a DateTime object. DateTimes will be converted to the UTC timezone before output for consistency.
+
+ $article = new OpenGraphProtocolArticle();
+ $article->setPublishedTime('2011-11-03T01:23:45Z');
+ $article->setModifiedTime(new DateTime('now', new DateTimeZone('America/Los_Angeles')));
+ $article->setExpirationTime('2011-12-31T23:59:59+00:00');
+ $article->setSection('Front page');
+ $article->addTag('weather');
+ $article->addTag('football');
+ $article->addAuthor('http://example.com/author.html');
+
+Convert a global object to `` elements just as you would with `OpenGraphProtocol.`
+
+ $article->toHTML();
+
+### Combined
+
+A common use case might be storing Open Graph protocol objects in a Controller for use by your web application. You can add each object to an array and later iterate through the array for `` and `` outputs.
+
+ $ogp_objects = array($ogp,$article);
+ $prefix = '';
+ $meta = '';
+ foreach ( $ogp_objects as $ogp_object ) {
+ $prefix .= $ogp_object::PREFIX . ': ' . $ogp_object::NS . ' ';
+ $meta .= $ogp_object->toHTML() . PHP_EOL;
+ }
+
+ ?>
