Installation

Perform the following operations in order to use this package

Install via composer

composer require "shweshi/opengraph"

If you do not run Laravel 5.5 (or higher), then add the service provider in config/app.php:

Add Service Provider Open config/app.php and add shweshi\OpenGraph\Providers\OpenGraphProvider::class, to the end of providers array:

'providers' => array(
    ....
    shweshi\OpenGraph\Providers\OpenGraphProvider::class,
),

Next under the aliases array:

'aliases' => array(
    ....
    'OpenGraph' => shweshi\OpenGraph\Facades\OpenGraphFacade::class
),

If you do run the package on Laravel 5.5+, package auto-discovery takes care of the magic of adding the service provider.

Requirements

You need to install the DOM extension.

How to use

After following the above steps,

use OpenGraph;

$data = OpenGraph::fetch("https://unsplash.com/");

this will give you an array like this...

  array (
    'title' => 'Beautiful Free Images & Pictures | Unsplash',
    'description' => 'Beautiful, free images and photos that you can download and use for any project. Better than any royalty free or stock photos.',
    'type' => 'website',
    'url' => 'https://unsplash.com/',
    'image' => 'http://images.unsplash.com/photo-1542841791-1925b02a2bbb?ixlib=rb-0.3.5&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjEyMDd9&s=aceabe8a2fd1a273da24e68c21768de0',
    'image:secure_url' => 'https://images.unsplash.com/photo-1542841791-1925b02a2bbb?ixlib=rb-0.3.5&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjEyMDd9&s=aceabe8a2fd1a273da24e68c21768de0',
  )

You can also pass an optional parameter either true or false along with URL. When set false it will only fetch basic metadata and in case of true it will fetch all the other optional metadata as well like audio, video, music and twitter metatags as well.

$data = OpenGraph::fetch("https://unsplash.com/", true);

this will give you an array like this...

  array (
    'charset' => 'UTF8',
    'viewport' => 'width=device-width, initial-scale=1.0, maximum-scale=1.0, minimal-ui',
    'mobile-web-app-capable' => 'yes',
    'apple-mobile-web-app-capable' => 'yes',
    'apple-mobile-web-app-title' => 'Unsplash',
    'application-name' => 'Unsplash',
    'author' => 'Unsplash',
    'msapplication-config' => 'browserconfig.xml',
    'msapplication-TileColor' => '#ffffff',
    'msapplication-TileImage' => 'https://unsplash.com/mstile-144x144.png',
    'theme-color' => '#ffffff',
    'description' => 'Beautiful, free images and photos that you can download and use for any project. Better than any royalty free or stock photos.',
    'twitter:site' => '@unsplash',
    'twitter:title' => 'Beautiful Free Images & Pictures | Unsplash',
    'twitter:description' => 'Beautiful, free images and photos that you can download and use for any project. Better than any royalty free or stock photos.',
    'twitter:url' => 'https://unsplash.com/',
    'twitter:card' => 'summary_large_image',
    'twitter:image' => 'https://images.unsplash.com/photo-1546486610-e9fe4f1e6751?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjEyMDd9',
    'title' => 'Beautiful Free Images & Pictures | Unsplash',
    'type' => 'website',
    'url' => 'https://unsplash.com/',
    'image' => 'http://images.unsplash.com/photo-1546486610-e9fe4f1e6751?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjEyMDd9',
    'image:secure_url' => 'https://images.unsplash.com/photo-1546486610-e9fe4f1e6751?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjEyMDd9',
)

To fetch the metadata in a specific language you can pass the language as the third argument, this value will be used as the Accept-Language header.

$url = "https://ogp.me",
$allMeta = true, // can be false
$language = 'en' // en-US,en;q=0.8,en-GB;q=0.6,es;q=0.4
$data = OpenGraph::fetch($url, $allMeta, $language);

You can also pass additional Libxml parameters as the fourth argument ($options) https://www.php.net/manual/en/libxml.constants.php. Default options are set to suppress the reporting of errors and warnings

$data = OpenGraph::fetch($url, $allMeta, $language, $options);

You can use the fifth parameter to set the user-agent ($userAgent) of the request. The default is 'Curl'.

$data = OpenGraph::fetch($url, $allMeta, $language, $options, $userAgent);

Exception Handling

The fetch() method, returns a FetchException with aditional data at failure.

    try {
        $data = OpenGraph::fetch($url, true);
    } catch (shweshi\OpenGraph\Exceptions\FetchException $e) {
        $message = $e->getMessage();
        $data = $e->getData();
    }
