    'name' => 'Consectetur Adipiscing',
    'description' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor',
    'telephone' => '555-555-5555',
    'openingHours' => 'mon,tue,fri',
    'address' => [

        'postalCode' => '06514',
    ],
    'geo' => [
        'latitude' => '41.3958333',
        'longitude' => '-72.8972222',
    ],
]);

echo $context; // Will output the script tag

    'mainEntityOfPage' => [
        'url' => 'https://google.com/article',

    ],
]);

Using the JSON-LD in a Laracasts Presenter

Even though this example shows using the JSON-LD inside of a Laracasts\Presenter presenter, Laravel is not required for this package., _(*5)

/App/Presenters/BusinessPresenter.php

<?php

namespace App\Presenters;

use JsonLd\Context;
use Laracasts\Presenter\Presenter;

class BusinessPresenter extends Presenter
{
    /**
     * Create JSON-LD object.
     *
     * @return \JsonLd\Context
     */
    public function jsonLd()
    {
        return Context::create('local_business', [
            'name' => $this->entity->name,
            'description' => $this->entity->description,
            'telephone' => $this->entity->telephone,
            'openingHours' => 'mon,tue,fri',
            'address' => [
                'streetAddress' => $this->entity->address,
                'addressLocality' => $this->entity->city,
                'addressRegion' => $this->entity->state,
                'postalCode' => $this->entity->postalCode,
            ],
            'geo' => [
                'latitude' => $this->entity->location->lat,
                'longitude' => $this->entity->location->lng,
            ],
        ]);
    }
}

Generate the Tags

The generator comes with a __toString method that will automatically generate the correct script tags when displayed as a string., _(*6)

Inside of a Laravel View, _(*7)

echo $business->present()->jsonLd();

Inside of a Laravel View, _(*8)

{!! $business->present()->jsonLd() !!}

Custom Context Type

The first argument for the create($context, array $data = []) method also accepts class names. This is helpful for custom context types., _(*9)

<?php

namespace App\JsonLd;

use JsonLd\ContextTypes\AbstractContext;

class FooBar extends AbstractContext
{
    /**
     * Property structure
     *
     * @var array
     */
    protected $structure = [
        'name' => null,
        'description' => null,
        'image' => null,
        'url' => null,
    ];
}

$context = \JsonLd\Context::create(\App\JsonLd\FooBar::class, [
    'name' => 'Foo Foo headline',
    'description' => 'Bar bar article description',
    'url' => 'http://google.com',
]);

echo $context; // Will output the script tag
