How to extract youtube video link?

Question

YouTube

There is a page with a link to the youtube video - https://www.youtube.com/channel/UCXzMQPQhtyWZJl0XJ... This link does not open the video that is on the page at all, but, it seems, the first video of this channel. Hence the question: how to determine the real link to the video using PHP?

Answer 1

In the first link, the channel is generally indicated.
And in the second one, you can parse using Curl + SimpleHTMLDom.
There in the iframe you can get the link of the video itself on YouTube.
Or, in the iframe, already track the Youtube button (go to the video on YouTube itself) and receive a link from there.
