How it works?

Sioner Metadata Extractor can, before running completely in the determined amount of seconds (explained later), quickly run the search for the determined data and obtain this data without the need to use javascript, thus saving its execution time. To do this, just pass the data you want to obtain as mandatory in the first verification as parameter #4

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, null, null, ['website', 'title', 'image', 'description']);

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);

But if that doesn't happen, it will run the Browser with javascript to get the data. The time for which it will run by default is 3 seconds, but you can change this value by setting parameter #2

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, 2.5); //2.5 seconds

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);

We get og:image by default of 200x200, and if it's not found, the next image larger than that dimension will be returned. If none match, the largest is returned. But you can also set these values.

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, null, [250,300]); //250 width, 300 height

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);

And that way you can pass the parameters you want and build the way you want. Watch

use JeanKassio\Sioner\MetadataExtractor

$YourLink = "https://github.com/jeankassio/Sioner-Metadata-Extractor";

$code = new MetadataExtractor($YourLink, 5, [500,100], ['website', 'title', 'image', 'description']);

$response = $code->ExtractMetadata();

echo json_encode($response, JSON_UNESCAPED_UNICODE);
