        'title' => 'MetaHelper Rocks',
        'type' => 'website',
        'image' => array(
            'url' => 'http://example.com/logo.png',
            'secure_url' => 'https://example.com/logo.png',
            'type' => 'image/jpeg',
            'width' => '300',
            'height' => '500'
        )
    );
    $metaHelper->og($ogConfig)->view();

This would display the following meta tags: <meta charset="UTF-8"><meta property="og:title" content="MetaHelper Rocks">

`<meta property="og:type" content="website">`

`<meta property="og:image:url" content="http://example.com/logo.png">`

`<meta property="og:image:secure_url" content="https://example.com/logo.png">`

`<meta property="og:image:type" content="image/jpeg">`

`<meta property="og:image:width" content="300">`

`<meta property="og:image:height" content="500">`

Twitter Cards

Finally MetaHelper can also take care of Twitter Cards. MetaHelper caters for all the different cards which Twitter Cards provide (Summery Card, Summery Image Card, Photo Card, Gallery Card, App Card, Product Card, Player Card).

//To Create a Summery Card
$metaHelper = new MetaHelper();

$metaHelper->card('SummerCard', [
        'title' => 'This is a title',
        'description' => 'This is a description',
        'image' => 'http://example.com/logo.png',
    ]
);

//You can also change individual attributes
$metaHelper->setCard()->title("A New Title");

All attribute names of all the Twitter Cards available follow the below convention:

Twitter Card Attribute Style MetaHelper Style
twitter:app $helper->app()
twitter:app:name:googleplay $helper->appNameGoogleplay

The only exception is the Summery Card with Large Image where for its twitter:image:src the normal image attribuet is used.
