// $schemaReader = SchemaReader::forRdfaLite();
// $schemaReader = SchemaReader::forJsonLd();

// The URL the document was retrieved from. This will be used only to resolve relative
// URLs in property values. No attempt will be performed to connect to this URL.

$things = $schemaReader->readHtml($html, $url);               // An HTML document as a string

            // even if the schema.org property documents a single type (here, Offer).
            // See the Caveats section below for an explanation why.

                // Yes! we do have an offer, let's check its price.
                // Don't forget that all properties have zero or more values, let's take the first one:

                $price = $offer->price->getFirstValue();

                // For the same reason as above (see Caveats), always check the type of the value,
                // it could very well be a nested Thing instance, or null if there is no value.
