Question 1

How to extract embed code from a YouTube video using Embed?

Accepted Answer

Load the YouTube URL with $embed->get(), then access the embed code via $info->code->html. Embed automatically uses oEmbed or OpenGraph for platforms like YouTube, so no extra setup is needed beyond basic installation.

Question 2

Embed vs Goutte for PHP web scraping: which is better?

Accepted Answer

Use Embed for structured metadata extraction across multiple protocols (oEmbed, OpenGraph) from social media and content sites. Goutte is better for general-purpose web crawling and form interaction, as it's built on Guzzle and Symfony components.

Question 3

How to handle Instagram or Facebook content with Embed when tokens are needed?

Accepted Answer

Provide API tokens via settings: $embed->setSettings(['instagram:token' => 'your_token']). This allows Embed to access oEmbed endpoints reliably, but you'll need to obtain and manage tokens from Meta's developer platforms.

Question 4

Can Embed be integrated with Laravel for generating link previews?

Accepted Answer

Yes, install Embed via Composer in a Laravel project and use it in controllers or services. Ensure a PSR-17 implementation is available; popular ones like Guzzle are auto-detected, but you might need to configure HTTP clients for production.

Question 5

How to add a custom detector in Embed for specific metadata?

Accepted Answer

Create a class extending Embed\Detectors\Detector, implement the detect() method, and register it with $embed->getExtractorFactory()->addDetector(). The README provides an example for extracting robots tags from headers or meta tags.

Question 6

Does Embed work with custom websites that don't use oEmbed or OpenGraph?

Accepted Answer

Yes, Embed can scrape HTML from any website using its default detectors and the Document object for XPath queries. For better results, you can create custom adapters to handle site-specific structures or APIs.

Question 7

What are common errors when using Embed and how to troubleshoot them?

Accepted Answer

Common issues include missing PSR libraries, Curl errors, or timeout settings. Ensure dependencies are installed, check network connectivity, and adjust settings like 'timeout' in CurlClient. For specific sites, verify if API tokens or custom adapters are required.
